1970 Lincoln Cent Errors: Value Guide & Rare Varieties
What is your 1970 penny worth? Complete error & variety guide: 1970-S Small Date ($20–$2,464+), DDO FS-101 ($38,400 record), RPM, off-center strikes, clipped planchets, and Floating Roof trap. Free value lookup.
Most 1970 pennies are worth face value, but the rare 1970-S Small Date and legendary Doubled Die Obverse FS-101 can reach $38,400 — if you know exactly what to look for.
- • 1970-S DDO FS-101 (Doubled Die Obverse): $1,500–$38,400 — only ~50 specimens known
- • 1970-S Small Date: $20–$60 circulated; $70–$2,464+ uncirculated Red
- • 1970-S Small Date Proof: $50–$450+ (DCAM); PR69 DCAM record: $18,400
- • 1970-D RPM (Repunched Mint Mark): $15–$100
- • 1970-P & 1970-D standard: Face value to ~$5 uncirculated
⚠️ Warning: Machine doubling and the "Floating Roof" are massively overhyped online — realistic value is $5–$50, not the hundreds some eBay listings claim. The guide below shows you how to tell the difference.
1970 Lincoln Cent Errors Error Checker
Check your coin for valuable errors and varieties
Values shown are typical retail estimates as of 2025-01. Actual market prices fluctuate based on demand, eye appeal, and economic conditions.
Color designation (Red, Red-Brown, Brown) dramatically affects value for copper coins. Red (RD) examples command exponentially higher premiums.
The 1970-S DDO FS-101 is extremely rare (~50 known). Professional authentication by PCGS or NGC is mandatory before buying or selling.
Machine Doubling (flat, shelf-like) is NOT a valuable Doubled Die error. Do not confuse with the FS-101.
The Floating Roof is a common die state caused by die polishing. Despite high online asking prices, realistic value is $5–$50. Do not overpay.
Professional grading (PCGS/NGC) is recommended for any coin believed to be a Small Date or error variety.
Copper melt value (~$0.03) provides a floor for all 1970 bronze cents, but melting U.S. coins is prohibited by law.
That 1970 penny in your change jar could be extraordinary. Among the nearly five billion Lincoln cents struck that year at three mint facilities, two varieties stand apart as genuine numismatic treasures: the 1970-S Small Date, a modern key date that retains real value even worn, and the 1970-S Doubled Die Obverse FS-101 — one of only approximately 50 known examples — which set a world record of $38,400 at Heritage Auctions in August 2024. This guide gives you the exact diagnostics to identify every valuable variety and error before you spend it. For standard (non-error) 1970 cent values, see our complete 1970 Lincoln Cent value guide.
1970 Lincoln Cent: Specifications & Mintage
| Series | Lincoln Memorial Cent (1959–2008) |
| Composition | 95% Copper, 5% Zinc/Tin (solid bronze — not copper-plated zinc like modern cents) |
| Weight | 3.11 grams |
| Diameter | 19.00 mm |
| Copper Content | ~2.95 grams per coin |
| Melt Value | ~$0.03 (floor above face value; melting U.S. coins is prohibited by law) |
Mintage by Facility
| Mint | Mark | Mintage | Key Notes |
|---|---|---|---|
| Philadelphia | None | 1,898,315,000 | Common; often weak strike. Circulated: face value. Uncirculated Red: $0.50–$5.00. Check for off-center & clipped errors. |
| Denver | D | 2,891,438,900 | Most common; typically better luster. Circulated: face value. Uncirculated Red: $0.50–$5.00. MS67+ RD sold $2,820. Check for RPM. |
| San Francisco | S | 690,560,004 | Lowest business-strike mintage. Contains Small/Large Date varieties — see section below. Final year S-mint Lincoln cents entered regular circulation. |
| San Francisco (Proof) | S | 2,632,810 | Mirror-like finish; sold in annual Proof Sets. Both Small/Large Date varieties exist. Small Date Proof PR69 DCAM: $18,400. |
The 1970 cent's solid bronze composition means even common examples carry a copper melt premium of about $0.03 — a floor above face value. Standard circulated Philadelphia and Denver cents are generally worth face value only, with uncirculated Red examples reaching $0.50–$5.00. The real opportunity lies entirely in San Francisco varieties and error coins across all mints. For non-error values, see our 1970 Lincoln Cent value guide.
1970-S Small Date vs. Large Date: How to Tell Them Apart
The single most important distinction in 1970 Lincoln Cent collecting is the Small Date versus Large Date variety. Both exist only on San Francisco (S-mint) coins — both business strikes and proofs — produced from two different master hubs used during the year. Getting this right is worth anywhere from $20 to thousands of dollars on the same coin.
Small Date (top row) vs. Large Date (bottom row): all four diagnostic markers shown side by side.
The Four Diagnostic Tests
Use all four tests — never rely on just one. Worn or polished dies can make any single marker ambiguous.
| Feature | Small Date ✓ (Scarce) | Large Date (Common) |
|---|---|---|
| "7" Alignment (Primary Test) | High: Top of 7 aligns level with 1, 9, and 0 | Low: Top of 7 sits visibly below the other digits |
| "9" Shape (Expert Test) | Hooked: Inner loop curves sharply up, pointing to the middle of the 7 | Blunt: Inner loop points down or is squared off |
| LIBERTY (Support Only) | Weak: "TY" and "E" often barely visible or missing | Strong: Usually bold (unless die is polished) |
| "7" Surface (Fail-Safe) | Smooth: Diagonal stroke of 7 has no line | Creased: A horizontal ridge runs across the diagonal of the 7 |
High 7 (Small Date, left) vs. Low 7 (Large Date, right) — the primary identification test.
Hooked 9 (Small Date, left) vs. Blunt 9 (Large Date, right) — the most definitive diagnostic.
⚠️ LIBERTY Weakness Is Not Enough Alone
A weak LIBERTY can appear on Large Date coins struck from polished or worn dies — it is a necessary but not sufficient condition. Always confirm with the "High 7" and "Hooked 9" tests before drawing any conclusion.
Weak LIBERTY on Small Date (left) vs. bold LIBERTY on Large Date (right). Use this as supporting evidence only.
1970-S Small Date Business Strike: Values by Grade
The Small Date is considered a modern key date — unlike most modern cents, it holds genuine numismatic value even in worn condition. The Red (RD) color designation (original copper luster intact) is critical for top prices.
- Circulated BN/RB:$20–$60
- MS64–MS65 RD:$70–$120
- MS66 RD:~$160+
- MS67 RD:$600–$2,464(auction record: PCGS MS67 RD, 2008)
1970-S Large Date Business Strike: Values by Grade
The Large Date represents the vast majority of the ~690 million S-mint business strikes. Value is driven almost entirely by condition — and even a common Large Date can conceal the valuable DDO FS-101 error.
- Circulated:$0.10–$0.30
- MS65 RD:$10–$15
- MS67+ RD:$1,500(condition rarity only)
💡 Always Check Your Large Date for the DDO
The FS-101 Doubled Die Obverse exists on Large Date coins. Even a circulated Large Date worth $0.10 is worth examining under a loupe — a confirmed DDO FS-101 is worth $1,500 minimum.
1970-S Small Date Proof Values
Proof coins were struck on polished planchets with polished dies, sold in annual Proof Sets. The Cameo (CAM) and Deep Cameo (DCAM) designations — referring to frosted devices against mirror-like fields — multiply value dramatically on Small Date proofs.
- Impaired Proof:$30–$60
- Brilliant Proof:$50–$80
- PR67 DCAM:~$250
- PR68 DCAM:~$450
- PR69 DCAM:$18,400(PCGS, 2005 — auction record)
Professional grading by PCGS or NGC is essential for any Small Date Proof — the DCAM designation alone can multiply value many times. Note: the "weak LIBERTY" diagnostic is sometimes less pronounced on proofs due to careful die preparation; rely primarily on the High 7 and Hooked 9 tests.
1970-S Large Date Proof Values
The standard Large Date Proof is the coin found in most original 1970 Proof Sets. Affordable for all collectors, with value driven purely by condition perfection.
- Impaired Proof:$5–$15
- PR69 RD:$20–$35
- PR70 (perfect):$2,530(condition rarity)
Always check Large Date Proofs for the DDO FS-101 variety — even proof dies can produce the doubling error.
1970 Lincoln Cent Quick Checks: Do You Have Something Valuable?
Run through these five checks before spending your 1970 penny. Each takes under two minutes with a 10x loupe — a small magnifying glass designed for coin inspection — and a precision scale for the weight check.
Check #1: Doubled Die Obverse FS-101 — S-Mint Only
The mottoes LIBERTY and IN GOD WE TRUST on the front of the coin, and the date. Examine with a 10x loupe in bright, direct light.
Strong, widely separated doubling with a clockwise spread — most dramatic on IN GOD WE TRUST (all letters show distinct secondary images) and LIBERTY. Visible to the naked eye for experienced collectors. This is a Class I Rotated Hub variety.
Flat, shelf-like doubling (machine doubling) has zero value. Do NOT confuse with FS-103, a minor DDO showing only slight doubling on the "0" of the date — FS-103 is worth a tiny fraction of the FS-101.
Check #2: Repunched Mint Mark (D/D) — D-Mint Only
The D mint mark below the date on the front of the coin. Mint marks were hand-punched until 1990, creating opportunities for human error and multiple punches.
A secondary shadow D visible beneath, to the side of, or overlapping the primary D — with distinct, well-defined edges. The WRPM-004 variety shows a bold D over D South. Split serifs on the D letterform confirm the RPM.
A fuzzy or mushy-looking mint mark from normal die wear is NOT a Repunched Mint Mark (RPM). Look for a secondary image with distinct, clear separation — not just general blurriness.
Check #3: Wrong Planchet / Off-Metal Error — All Mints
The overall color, size, and weight of the coin. A cent struck on a dime planchet (copper-nickel clad) will appear silver-colored and is slightly smaller than a normal penny. A precision scale is required for confirmation.
A silver-colored 1970 cent weighing approximately 2.27 grams (standard 1970 cent is 3.11 grams). The color difference from bronze is distinct and unmistakable under normal light.
Plated or coated novelty coins (sold in gift shops or online) that have been silver-plated after leaving the mint. Environmental discoloration or chemical toning. Always verify with a precision scale — weight is the definitive test.
Check #4: Off-Center Strike — All Mints
The overall design. Part of Lincoln and the surrounding lettering will be missing, replaced by a blank crescent of unstruck metal along one edge — this happened when the planchet was off-center inside the striking chamber.
A clear blank crescent with the design clearly shifted. The date "1970" MUST be visible for maximum value. Higher percentages off-center command higher prices — a 1970-D struck 80% off-center with visible date was listed at approximately $90.
A weak area from a worn die (which affects detail, not positioning). Misaligned die errors show the full design slightly shifted but no blank crescent. Post-mint damage (bent, filed, or ground edges) is NOT an error coin.
Check #5: Clipped Planchet — All Mints
The rim and edge of the coin. A curved, straight, or ragged bite will be missing from the planchet — this happened when the blanking punch overlapped a previously punched hole in the metal strip.
A smooth, unstruck edge at the clip location, plus a corresponding weak rim area directly opposite (called the Blakesley effect). Multiple clips on the same coin increase value significantly.
Post-mint damage from pliers, vise grips, or deliberate cutting produces rough, irregular edges. An authentic clip has a smooth, unstruck edge and the design shows weakness opposite the clip — without both features, it is likely damaged.
1970 Lincoln Cent: Complete Error & Variety Value Table
| Error / Variety | Designation | Mint | Rarity | Value Range | Auction Record |
|---|---|---|---|---|---|
| DDO FS-101 | FS-101 | S | Extremely Rare (~50 known) | $1,500–$38,400+ | $38,400 (MS66+ RD, Aug 2024) |
| Small Date Business Strike | — | S | Scarce (Key Date) | $20–$2,464+ | $2,464 (MS67 RD, 2008) |
| Small Date Proof | — | S | Scarce | $50–$18,400+ | $18,400 (PR69 DCAM, 2005) |
| Repunched Mint Mark (RPM) | WRPM-004 | D | Uncommon | $15–$100 | — |
| Wrong Planchet / Off-Metal | — | All | Extremely Rare | $1,000+ | $1,000+ |
| Off-Center Strike | — | All | Uncommon | $75–$500 | ~$90 (80% off-center) |
| Clipped Planchet | — | All | Uncommon | $20–$50 | $43.20 (1970-S) |
| Large Date Business Strike | — | S | Very Common | $0.10–$15 | $1,500 (MS67+ RD) |
| Large Date Proof | — | S | Common | $5–$35 | $2,530 (PR70) |
| Minor DDO FS-103 | FS-103 | S | Uncommon | Fraction of FS-101 | — |
| Floating Roof | — | All | Common Die State | $5–$50 | — |
Values are typical retail estimates as of January 2025. Red (RD) color designation dramatically increases value for all uncirculated copper examples. Machine doubling and post-mint damage carry no numismatic premium.
1970 Lincoln Cent Jackpots: Detailed Variety & Error Guide
1970-S Doubled Die Obverse FS-101 — The King of 1970 Errors
Normal 1970-S (left) vs. DDO FS-101 (right), showing dramatic doubling on IN GOD WE TRUST and LIBERTY.
Origin & Background
The 1970-S DDO FS-101 (formerly cataloged as FS-029) ranks as the third most important doubled die in the entire Lincoln Cent series, surpassed only by the legendary 1958 DDO and the 1969-S DDO. The error occurred during the hub-pressing process: when a working die received multiple impressions from the master hub in slightly different rotational positions, a doubled image was permanently imprinted onto the die. Every coin subsequently struck by that die carries the error. The misalignment follows Class I (Rotated Hub) mechanics, which concentrates the most dramatic doubling at the coin's periphery.
How to Identify
- IN GOD WE TRUST — The strongest doubling on the coin. All letters show distinct, widely separated secondary images with a strong clockwise spread.
- LIBERTY — Dramatic doubling with clear separation across all letters.
- Date "1970" — Also doubled, though less pronounced than the peripheral mottoes.
- The doubling is unmistakable under a 10x loupe and perceptible to the naked eye for experienced collectors.
True DDO FS-101 (left) with round, separated doubling vs. machine doubling (right) — flat, shelf-like, worthless.
False Positives to Avoid
FS-103 (Minor DDO): This is the critical pitfall. FS-103 shows only minor doubling on the "0" of the date and carries a small fraction of FS-101's value. Confusing the two can cost thousands of dollars. Machine doubling (MD) is flat and shelf-like — no numismatic value. Die Deterioration Doubling (DDD) from worn dies is mushy and indistinct. True hub doubling has rounded, fully separated secondary images.
Rarity Note
Only approximately 50 examples are known. Most survivors are Mint State Red — suggesting a specific batch was set aside by a collector or speculator in 1970. Brown (circulated) examples are paradoxically rarer, with fewer than an estimated 10 known, though Red examples command higher prices due to superior aesthetics.
Market Values
- MS64 RD (entry level):$1,500–$1,800
- MS65 RD:$2,500–$6,500(eye appeal and CAC approval affect price within range)
- MS66 RD:$13,200
- MS66+ RD (world record):$38,400
Auction Record
$38,400 for PCGS MS66+ RD (Heritage Auctions, August 2024).
1970-D Repunched Mint Mark (D/D)
WRPM-004: bold secondary D visible south of the primary D mint mark under magnification.
Origin & Background
Until 1990, mint marks on Lincoln cents were hand-punched individually into each working die — a manual process prone to misalignment and double strikes. A Repunched Mint Mark (RPM) occurs when the punch was applied more than once in slightly different positions. Several RPM varieties are cataloged for the 1970-D; the most notable, WRPM-004 (also known as RPM #2 in CONECA files), shows a bold D over D South alignment.
How to Identify
- Under 10x magnification, look for a secondary D visible beneath, to the side of, or overlapping the primary D.
- The shadow D should have defined, sharp edges — not just general blurriness from die wear.
- Split serifs on the D letterform are a strong indicator.
- WRPM-004 shows a bold secondary D positioned south of the primary.
False Positives to Avoid
Normal die deterioration can make a mint mark appear fuzzy or doubled, but without the distinct secondary edges of a true RPM. Die polishing can also soften mint mark edges. Always look for a second, defined D — not just a blurry one.
Market Values
- Most examples:$15–$100(depending on variety strength and grade)
1970 Lincoln Cent on Wrong Planchet (Off-Metal Error)
A 1970 cent struck on a dime planchet (right) appears silver-colored and smaller than a normal bronze cent (left).
Origin & Background
Wrong planchet errors occur when a planchet (blank coin disc) intended for a different denomination accidentally enters the penny press and receives a cent design. A 1970 cent struck on a clad dime planchet is silver-colored (copper-nickel alloy) and significantly lighter than a normal bronze cent — a spectacular and immediately visible error.
How to Identify
- Coin appears distinctly silver-colored (not just toned or discolored).
- Weighs approximately 2.27 grams — significantly below the standard 3.11 grams. Use a precision scale.
- May appear slightly smaller than a normal penny due to the dime planchet diameter.
False Positives to Avoid
Silver-plated novelty cents (sold commercially) are the most common source of confusion. Environmental chemicals can cause dramatic color changes. Always verify weight with a precision scale — post-mint plating adds weight rather than reducing it.
Market Values
- Dime planchet:$1,000+
1970 Lincoln Cent Off-Center Strike
Off-center 1970 Lincoln Cent with visible date — both conditions required for maximum value.
Origin & Background
Off-center strikes occur when the planchet is not properly centered within the coin collar (the ring that holds the blank in place) when the dies come together. The resulting coin has a blank crescent of unstruck metal on one side and a portion of the design missing on the other.
How to Identify
- A clear crescent of smooth, blank, unstruck metal is visible along one edge.
- The design (Lincoln's portrait and mottoes) is visibly shifted away from center.
- Date visibility is critical — a coin without a visible date cannot be attributed to a specific year and loses most of its premium value.
- Higher percentages off-center are rarer and more valuable.
Market Values
- 10%–50% off-center (date visible):$75–$500
- ~80% off-center (date visible):~$90(1970-D example)
1970 Lincoln Cent Clipped Planchet
Clipped planchet with the curved bite at top and Blakesley effect (weak rim) visible at the bottom opposite edge.
Origin & Background
Clipped planchets result from the blanking process, where a moving strip of metal is punched to create coin blanks. If the strip does not advance far enough, the next punch overlaps a previously punched hole, cutting a curved (or straight, or ragged) section from the blank. The coin is struck with this pre-existing clip.
How to Identify
- A smooth, rounded (curved clip), straight, or ragged missing section along the coin's edge.
- The Blakesley effect: a weak or flat area on the rim directly opposite the clip — the definitive authentication marker. Without this, the clip may be post-mint damage.
- Multiple clips on the same coin increase value significantly.
Auction Record
$43.20 for a 1970-S clipped planchet example.
Market Values
- Single curved clip:$20–$50
- Multiple clips (same coin):Significantly higher — each additional clip adds rarity
1970 Lincoln Cent Traps: Common Mistakes That Cost Collectors Money
These three "errors" generate enormous online hype but little real value. Knowing them saves you from overpaying — or from embarrassment when a dealer turns down your "rare" find.
⚠️ Machine Doubling (Mechanical Doubling / Strike Doubling)
The date, lettering, or Lincoln's profile appears doubled, with a secondary image shifted in one direction.
A loose or bouncing die produces a secondary impression during the striking process — after the design is already on the coin. This is a mechanical (striking) phenomenon, not a die manufacturing error.
- Machine doubling is flat and shelf-like — the secondary image appears as a raised platform, not a separate rounded element.
- True hub doubling (like FS-101) has fully rounded, three-dimensional secondary letters with visible space between them.
- Machine doubling is one-directional; hub doubling shows rotational spread.
Value: No numismatic premium. Worth face value only.
⚠️ Floating Roof — Reverse Die State (Massively Overhyped)
On the reverse Lincoln Memorial, the roof appears visually disconnected from the columns — it seems to "float" above the building.
Mint employees routinely polished dies to remove clash marks. Because the incuse lines forming the roof connection are very shallow, heavy polishing abraded them away entirely. This is a die state — a natural result of routine die maintenance, not an error.
Floating Roof: roof of the Lincoln Memorial appears disconnected from the columns — a common die state, not a rare error.
- Despite eBay listings asking $350 or more, professional numismatists value raw circulated examples at $5–$15 and certified high-grade examples up to $50 at most.
- This is a common die state — not a scarce error with a fixed population.
- The effect can appear on any 1970 cent from any mint with a heavily polished die.
Value: $5–$50 (certified high-grade). Do not overpay.
⚠️ Post-Mint Damage & Cleaned Coins
A shiny, bright-looking coin that appears uncirculated, OR a coin with unusual marks, bends, or altered surfaces that might look like an error.
Coins are cleaned with household chemicals, polished with abrasives, or physically damaged after leaving the mint. Copper is highly reactive and can be dramatically altered by chemicals, creating bizarre color effects that mimic errors.
- Cleaned coins show hairline scratches under magnification — parallel fine lines from abrasive cleaning.
- Genuine uncirculated Red coins have an even, natural copper glow; cleaned coins have a harsh, unnatural brightness or artificial rainbow toning.
- Any coin that was bent, cut, ground, or altered after minting is worth face value only — grading services will return it as "Altered."
Value: Face value only. Cannot be certified by PCGS or NGC.
1970 Lincoln Cent Grading: How Grade & Color Affect Value
For 1970 Lincoln cents, two factors determine value above all others: grade (amount of wear) and color designation (how much original copper luster remains). Understanding the color system is essential — it is unlike any other series.
The Three Color Designations
- RD (Red)Original copper color intact — 95% or more. The most valuable designation. A 1970-S Small Date in MS65 RD is worth $70–$120; the same coin in MS65 BN might fetch $15–$25.
- RB (Red-Brown)Mixed original red and brown toning — 5–94% red. Intermediate value. Common in lightly circulated or improperly stored uncirculated examples.
- BN (Brown)Fully oxidized — less than 5% red remaining. Lowest value. Standard for circulated examples.
Grade Thresholds That Matter
- MS65 RD is the primary investment-grade threshold for the Small Date variety ($70–$120).
- MS67 RD is a population rarity for 1970 cents — coins were dumped into bags and typically suffer contact marks. Expect to pay $600+ for a genuine example.
- For the DDO FS-101, all grades are significant — even a Brown circulated example is historically rare.
Do not clean your 1970 cents. Even gentle cleaning destroys the original surface and reduces value by 50–90%.
1970 Lincoln Cent Authentication: When & Why to Get Certified
Professional grading by PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Company) is not just for ultra-rare coins — for the 1970 Lincoln Cent, it is often the difference between selling for $30 and selling for $300.
Submit for Grading If:
- You believe you have a 1970-S Small Date in any uncirculated grade (RD surface required for top value).
- You believe you have the DDO FS-101 — authentication is mandatory before any sale. The ~50-coin population means buyers require a PCGS or NGC holder.
- You have a Small Date Proof with strong cameo contrast — a DCAM designation can add hundreds to thousands of dollars in value.
- You have any mechanical error (off-center, wrong planchet, clipped planchet) in uncirculated condition.
Strategy Tips
- For the DDO FS-101 specifically, submit to PCGS — the coin is listed in their CoinFacts registry and buyers specifically seek PCGS-certified examples.
- Handle suspected valuable coins only by the edges. Store in a protective flip or 2x2 holder before submission.
- Do NOT clean, dip, or wipe the coin before submission. Any sign of cleaning results in a "Details" designation that dramatically reduces value.
- Consider CAC (Certified Acceptance Corporation) sticker verification for DDO FS-101 examples — CAC approval further increases buyer confidence and realized prices.
For local coin dealer referrals and specialist contacts for 1970 Lincoln Cent varieties, consult the American Numismatic Association (ANA) dealer directory at money.org.
1970 Lincoln Cent Errors: Frequently Asked Questions
How do I know if my 1970-S cent is a Small Date or Large Date?
Use these four checks: (1) High 7 — on a Small Date, the top of the 7 aligns level with the 1, 9, and 0. On a Large Date, the 7 sits noticeably lower. (2) Hooked 9 — the inner loop of the 9 curls sharply upward on a Small Date; it is blunt and squared on a Large Date. (3) Weak LIBERTY — the Small Date typically shows faint or missing "TY" and "E," but this alone is not conclusive. (4) Creased 7 — a horizontal ridge runs across the diagonal of the 7 on Large Date coins only. Confirm with at least two tests.
What is the 1970-S DDO FS-101, and how do I spot it?
The Doubled Die Obverse FS-101 is one of only approximately 50 known examples — the third most important doubled die in the entire Lincoln cent series. It shows strong, widely separated doubling on LIBERTY and IN GOD WE TRUST, with a clockwise spread caused by a rotational hub misalignment during die manufacture. The doubling is dramatic and visible to the naked eye for experienced collectors. Do not confuse it with FS-103 (minor doubling on the "0" only) or machine doubling (flat, shelf-like — no value).
Is the "Floating Roof" on my 1970 penny worth anything?
Very little, despite what eBay listings claim. The Floating Roof is a common die state caused by Mint employees polishing away the shallow die lines that connect the Memorial roof to its columns. Professional numismatists value raw circulated examples at $5–$15 and certified high-grade examples at up to $50. It is not a major error, its supply is not fixed, and it should not command hundreds of dollars.
Why is the "Red" (RD) color designation so important for 1970 cents?
The 1970 cent is 95% copper, which oxidizes over time from red to red-brown to brown. Grading services designate uncirculated coins as Red (RD), Red-Brown (RB), or Brown (BN). A 1970-S Small Date in MS65 Red may be worth $70–$120; the same coin in MS65 Brown might bring only $15–$25. For investment-grade coins, Red designation is essentially mandatory. Never clean a 1970 cent — even gentle cleaning permanently destroys the surface and the value.
My 1970 penny looks silver-colored. Is it worth anything?
Possibly — but verify first. A 1970 cent struck on a clad dime planchet would appear silver-colored and weigh approximately 2.27 grams (vs. the standard 3.11 grams). Weigh it on a precision scale immediately. If it weighs 3.11 grams, it has likely been plated or chemically altered after leaving the mint — a common novelty with no numismatic value. Only a confirmed underweight silver-colored coin is a genuine wrong-planchet error worth $1,000+.
Does the 1970-S Small Date only apply to business strikes?
No — the Small Date and Large Date varieties exist in both business strike and Proof format. Proof Small Dates are highly desirable. Standard brilliant proofs trade for $50–$80, while Deep Cameo (DCAM) examples can reach $250–$450+. The record for a Proof Small Date is $18,400 for a PCGS PR69 DCAM example in 2005. The same four diagnostic tests (High 7, Hooked 9, Liberty weakness, and 7 surface crease) apply to proofs, though the Liberty diagnostic may be less pronounced due to careful die preparation.
Are 1970 Philadelphia and Denver cents worth anything?
Standard circulated examples are worth face value, with the 95% copper content providing a melt floor of about $0.03 (though melting U.S. coins is prohibited by law). Uncirculated Red examples can reach $0.50–$5.00. However, both mints produced mechanical errors — off-center strikes, clipped planchets, and wrong-planchet errors — that can be worth $20 to $1,000+. Denver cents are also worth checking for Repunched Mint Mark (RPM) varieties, worth $15–$100. A 1970-D in exceptional MS67+ RD has sold for $2,820.
Should I submit my 1970-S Small Date to PCGS or NGC before selling?
Yes — for any uncirculated Small Date, professional grading is strongly recommended. The grade and especially the Red/Red-Brown/Brown designation will have an enormous impact on realized price. For the DDO FS-101, certification is not just recommended — it is essentially required by serious buyers. The population is so small (~50 known) that unattributed raw examples face extreme buyer skepticism.
