Check your coin for valuable errors and varieties
Values shown are typical retail estimates for certified (PCGS/NGC) coins as of 2025-01. Raw (uncertified) coins generally trade at a 30–50% discount due to authentication risk.
Error coin values vary significantly based on grade, eye appeal, Cameo/Deep Cameo designation, and current market conditions.
Professional authentication (PCGS/NGC) with variety attribution is mandatory for high-value die varieties (FS-101, FS-102, FS-103, FS-801). Standard grading does not automatically attribute FS numbers.
Machine Doubling (flat, shelf-like doubling) is extremely common on 1967 Kennedy Half Dollars and has ZERO numismatic premium. It is the single most common reason for grading service rejection on 1967 submissions.
All 1967 Kennedy Half Dollars lack mintmarks (suspended 1965–1967). The presence of a 'D' or 'S' mintmark on a 1967 coin indicates a counterfeit or altered date.
Silver melt value fluctuates with the spot price of silver. The bullion value noted is approximate and serves as a price floor for circulated specimens.
The SMS vs. Business Strike distinction is critical for accurate variety attribution. FS-101 exists only on SMS coins; FS-102, FS-103, and FS-801 exist only on Business Strikes.
In 1967, the U.S. Mint struck nearly 300 million Kennedy Half Dollars at emergency speeds to ease a national coin shortage — and the pressure shows. A transitional 40% silver clad composition, an experimental Special Mint Set program, and overworked dies created the perfect conditions for dramatic errors and rare varieties. One SMS coin with a Quadrupled Die Obverse has sold for over $12,600. The question is whether yours hides the same secret — and this guide will tell you exactly where to look.
1967 Kennedy Half Dollar Specifications & Mintage
Before hunting for errors, you need to know what a standard 1967 Kennedy Half Dollar looks like. Any deviation from the specs below is a potential error.
| Specification | Standard Value | Why It Matters for Errors |
|---|---|---|
| Composition | 40% Silver Clad (outer layers: 80% Ag / 20% Cu; core: 21% Ag / 79% Cu) | This layered "silver sandwich" is why Missing Clad Layer errors exist |
| Weight | 11.50 grams (tolerance: 11.10g–11.90g) | Coins under 10.1g are Missing Clad candidates; coins over 12.0g may be wrong-planchet |
| Diameter | 30.61 mm | Significantly larger = broadstrike; significantly smaller = struck on wrong planchet |
| Edge | Reeded (150 reeds) | Smooth edge = broadstrike or severe post-mint damage |
| Silver Content | 0.1479 troy ounces | Establishes the melt-value price floor (~$3.50–$4.00) |
| Mintmark | None — suspended 1965–1967 | Any "D" or "S" mintmark = counterfeit or altered date |
| Business Strike Mintage | 295,046,978 | Massive volume caused die overuse → Machine Doubling and die deterioration |
| SMS Mintage | 1,863,344 | Lower mintage + careful handling makes high-grade SMS coins scarcer and more valuable |

🔍 Critical: How to Tell SMS From Business Strike
All 1967 halves lack mintmarks. The only way to tell them apart is surface finish — and it matters enormously because the most valuable varieties (FS-101) exist only on SMS coins, while FS-102, FS-103, and FS-801 exist only on Business Strikes.
- Rotating "cartwheel" spokes of light when tilted under a single light source
- Slightly rounded or beveled rims from high-speed ejection
- Common bag marks and contact dings even on uncirculated examples
- Associated varieties: FS-102, FS-103, FS-801
- Smooth satin or mirror-like fields — no cartwheel spokes
- Characteristically sharp, square rims — the clearest tell
- Frosted devices + mirrored fields = Cameo or Deep Cameo designation
- Associated varieties: FS-101 (QDO)

1967 Kennedy Half Dollar Quick Checks: Do You Have a Valuable Error?
Use a 10x loupe (a magnifying glass that shows 10× magnification — available for a few dollars at any coin shop or online) and a single direct light source. Work through these checks in order.
Check 1 — SMS Quadrupled Die Obverse (FS-101)
The word TRUST in the motto "IN GOD WE TRUST." Also check Kennedy's lips and chin, and the date. SMS coins only — satin or mirror finish with sharp square rims.
Four distinct sets of serifs on the letters of TRUST — they look like shingled or stacked layers slightly offset. Kennedy's lips and chin show multiple extra outlines (a double or triple profile). The date shows quadrupling.
Machine Doubling (flat, shelf-like steps with no rounded relief). This variety does NOT exist on Business Strikes — a polished or "whizzed" business strike is not an SMS coin.
Check 2 — Doubled Die Obverse FS-102 / CONECA DDO-007 (Business Strikes)
IN GOD WE TRUST and the hair strands at the very top (crown) of Kennedy's head. Also check the date "1967."
Distinct notching (split corners) on the serifs of "IN GOD." Hair strands at the crown show a "spaghetti" effect — each strand appears doubled. The date shows thickening and notching. Class V Pivoted Hub doubling.
Not FS-103 (which focuses on LIBERTY, not hair detail). Machine Doubling shows flat shelves, not rounded split serifs. SMS coins cannot have this variety.
Check 3 — Doubled Die Obverse FS-103 / CONECA DDO-001 (Business Strikes)
LIBERTY along the top rim — specifically the letters "RTY." Also check "IN GOD" and look under Kennedy's ear and across the nose for a ghostly jagged line.
Triple spread on "RTY" — three overlapping impressions. Split serifs on B, E, and R. On Stage B coins: a die clash visible as a ghostly eagle-wing outline under Kennedy's ear. Class I Rotational doubling.
Not FS-102 (which focuses on hair and IN GOD, not LIBERTY). Machine Doubling has flat, shelf-like steps — no rounded serifs or split terminals.
Check 4 — Doubled Die Reverse FS-801 / CONECA DDR-001 (Business Strikes)
The ring of stars above the eagle's head on the reverse. Also check "UNITED STATES OF AMERICA."
Star points show distinct notching — like a "V" shape cut into the tip of each star, especially those directly above the eagle. Serifs of "OF AMERICA" show clear splitting. Notching is crisp and well-defined. Class II Distorted Hub doubling.
Mushy, undefined flattening on star points is Machine Doubling or die deterioration — not a true Doubled Die. Normal star points are sharp and singular with no notching.
Check 5 — Missing Clad Layer (Scale Required)
Both faces of the coin. Is one side fully copper-red while the other is silver? Then weigh the coin immediately on a digital scale.
One copper-red face AND a weight of 9.4g–10.1g. The copper side may show weak detail due to planchet thinness. The transition from silver to copper at the rim edge is sharp and mechanical.
An acid-dipped or copper-plated coin will weigh the normal ~11.5g. If it looks copper but weighs ~11.5g, it is environmental damage or a novelty plated coin — not a genuine error.
Trap Check — Machine Doubling (Extremely Common, Zero Value)
The date "1967," Kennedy's profile, and all lettering. If you see doubling anywhere on a 1967 half, this check comes first.
Flat, shelf-like steps alongside letters that make letters look narrower. The secondary image has no rounded relief. Extremely common because 1967 dies ran at maximum emergency speeds and would loosen in their chucks.
True Doubled Dies (FS-101, 102, 103) show split serifs and a rounded secondary image that widens the letter. Machine Doubling is flat and reduces letter width. If the secondary image looks like a step, it is MD. See Traps section →

SMS Coin Varieties
1967 SMS Quadrupled Die Obverse — FS-101 / CONECA DDO-006
TRUST on a normal SMS coin (left) vs. FS-101 showing four stacked sets of serifs (right).
Origin & Background
SMS dies were hubbed multiple times to ensure a sharp image. For the FS-101, the working die received at least four separate hub impressions, and the hub was misaligned — rotated or pivoted slightly — for each subsequent impression. This is a Class II/V spread and is the "King" of all 1967 Kennedy Half Dollar varieties. It can only exist on SMS coins because SMS and Business Strike dies were made separately.
How to Identify
- Primary pickup: Four distinct sets of serifs on the "T" of TRUST — they look like stacked shingles or papers fanned out
- Kennedy's lips and chin show multiple extra outlines — a double or even triple profile
- The date "1967" shows quadrupling on the numerals
- The coin must be an SMS (satin/mirror finish, sharp square rims, no cartwheel luster)
- Die polish lines (fine raised lines on the coin surface from die preparation) are often visible on SMS specimens
False Positives to Avoid
Machine Doubling on SMS coins shows flat, shelf-like steps — not rounded quadrupling with stacked serifs. Any doubling that reduces letter width rather than widening and layering it is not the FS-101. Polished or "whizzed" business strikes are sometimes sold as SMS coins — verify the sharp square rim and absence of cartwheel luster before proceeding.
Market Values
- MS63: $300–$450
- MS65: $600–$900
- MS66/67: $1,500–$3,500+
- Superb Gem with Deep Cameo: $10,000+
Auction Record
$12,600 for an MS-69 Ultra Cameo specimen (Heritage Auctions / Stack's Bowers). Deep Cameo SMS examples — frosted devices over fully mirrored fields — are a rarity within a rarity on this date. See the PCGS CoinFacts page for FS-101 and the Variety Vista diagnostic page for die markers.
Business Strike Varieties
1967 Doubled Die Obverse — FS-102 / CONECA DDO-007
FS-102: split serifs on "IN GOD" (top) and "spaghetti" doubled hair strands (bottom).
Origin & Background
This is a Class V Pivoted Hub Doubled Die — the pivot point is near the rim (approximately the 6 o'clock position), so the spread increases as you move away from that point. The doubling is therefore most dramatic on the upper elements of the obverse, which are farthest from the pivot.
How to Identify
- Primary pickup: Distinct notching on the corners of "IN GOD" — serifs split like a snake's tongue
- Hair strands at the crown of Kennedy's head show clear duplication — individual strands appear doubled, creating a "spaghetti" effect
- Date "1967" shows distinct thickening and notching on numeral edges
- Must be a Business Strike (cartwheel luster, slightly rounded rims)
- Cross-referenced as CONECA DDO-007 and Wexler DDO-007
False Positives to Avoid
Do not confuse with FS-103, which shows its strongest doubling on LIBERTY (not the hair or IN GOD). Machine Doubling on the hair area looks like flat, featureless shelving — not the rounded, strand-by-strand separation of FS-102. SMS coins cannot have this variety.
Auction Record
An NGC MS-64 example was sold at GreatCollections — see the GreatCollections lot #1800882. MS66/67 examples are extreme condition rarities with populations often in single digits. See PCGS CoinFacts for FS-102.
1967 Doubled Die Obverse — FS-103 / CONECA DDO-001
FS-103: triple spread on "RTY" in LIBERTY (left); die clash ghost line under Kennedy's ear on Stage B (right).
Origin & Background
A Class I Rotational Doubled Die — the die rotated around its center point between hubbings, creating a uniform rotational spread that affects the entire obverse. Unlike the FS-102 pivot doubling, FS-103 creates a spread that distributes evenly across the coin rather than increasing toward one area. An advanced Stage B die state adds a dramatic die clash as a confirmatory marker.
How to Identify
- Primary pickup: Triple spread on "RTY" — the letters R, T, and Y in LIBERTY each show three overlapping images
- Split serifs on B, E, and R at the base of LIBERTY are clearly visible
- Stage B confirmatory marker: a ghostly jagged line (eagle-wing die clash impression) visible under Kennedy's ear and across the nose — if you see this clash, check LIBERTY immediately
- Cross-referenced as CONECA DDO-001 and Wexler DDO-001
False Positives to Avoid
Not FS-102, which focuses on hair strands and IN GOD. Machine Doubling on LIBERTY shows a flat, shelf-like step — not the rounded triple spread with split terminals. The die clash under the ear is unique and is not present on any other 1967 variety. See Variety Vista's FS-103 diagnostic page for die photos.
Auction Record
No single record-setting auction documented. High-grade certified examples (MS65+) are seldom offered. Circulated examples offer excellent value entry points at $40–$70.
1967 Doubled Die Reverse — FS-801 / CONECA DDR-001
FS-801: normal star point (left) vs. V-shaped notching on star tips diagnostic of the DDR (right).
Origin & Background
A Class II Distorted Hub Doubled Die on the reverse. Reverse varieties are generally scarcer for the 1967 date, making the FS-801 the premier reverse collectible of this year. The distortion affected the working die before any coins were struck, so every coin struck from that die carries the variety.
How to Identify
- Primary pickup: Stars above the eagle show crisp "V"-shaped notching at their points — like a notch cut into the tip of each star
- Serifs of "OF AMERICA" show clear splitting
- The notching must be crisp and well-defined — not mushy or vague
- Check multiple stars; if only one is affected, it may be a contact mark rather than the variety
- Cross-referenced as CONECA DDR-001 and Wexler DDR-001
False Positives to Avoid
Mushy, undefined flattening on star points is Machine Doubling or die deterioration — extremely common on 1967 high-mintage business strikes. Normal coins have sharp, singular star points. The FS-801 notching is crisp, bilateral, and present on multiple stars simultaneously. See PCGS CoinFacts for FS-801 and Variety Vista's 1967 DDR page.
Auction Record
A PCGS AU-58 example sold at GreatCollections lot #156115. MS65 examples have been described as "Super Rare" by specialist dealers.
Planchet & Striking Errors
1967 Kennedy Half Missing Clad Layer
Missing Clad Layer: silver face (left) vs. exposed copper-red face (right) on the same coin.
Edge profiles: normal 40% silver clad (left), genuine missing clad layer (center), and copper-nickel fake (right).
Why This Happens on 1967 Halves
The 1967 Kennedy Half's "silver sandwich" — 80% silver outer layers bonded to a 21% silver copper core — was manufactured using immature bonding technology. Gas pockets or oxidation on the metal surfaces prevented solid bonding. During blanking (punching the coin blanks), stress would cause the weakly bonded outer layer to delaminate, creating a planchet that was silver on one side and bare copper core on the other. When struck, the thinner planchet produced a weak image on the copper side.
How to Authenticate
- Weight is mandatory: A genuine missing clad layer coin must weigh 9.4g–10.1g
- Smooth metal flow lines are visible on the copper side (weak strike, but not pitted)
- The transition from silver to copper at the rim edge is sharp and mechanical — not gradual or chemically eroded
- A "Red" copper face (original luster retained) commands a higher price than a "Brown" (oxidized) face
False Positives to Avoid
Acid-dipped coins have pitted, rough surfaces and weigh ~11.5g. Copper-plated novelty coins weigh ~11.5g or more. Environmental (ground) finds may have a brownish copper color but will show pitting and weight close to 11.5g. The scale is the ultimate arbiter — if it weighs ~11.5g, it is not a genuine missing clad error.
1967 Kennedy Half Off-Center Strike
How to Identify
- The design is shifted off the planchet, leaving a crescent of blank metal on one side
- Critical requirement: Because 1967 halves have no mintmarks, the date "1967" MUST be visible to attribute the coin to this year — without it, the coin is a generic "Kennedy Half Off-Center" worth less
- Higher percentages off-center with date visible are exponentially more valuable
False Positives to Avoid
A broadstrike (design spreads beyond normal diameter but stays centered) is a different error type. Post-mint damage from coin dryers or other machinery can create irregular edges — look for uniform wear on the existing rim sections; a true off-center has crisp, sharp metal on the shifted portion.
1967 Kennedy Half Struck on Wrong Planchet
Kennedy Half design struck on a quarter-sized planchet — design is cut off at the smaller diameter edge.
How to Identify
- Coin is significantly smaller in diameter with parts of the design cut off at the edges
- Quarter planchet: weight ~5.67g; edge shows a stark orange-red copper core of copper-nickel clad — very different from the grey/silver core of the 40% half dollar
- Nickel planchet: weight ~5.0g; solid cupronickel composition throughout
- The metallurgical mismatch proves planchet feed line contamination between the quarter and half dollar production lines — a historically documented phenomenon
False Positives to Avoid
A normal 1967 half that has been ground down or damaged post-mint. Check for complete, undamaged reeding on remaining rim sections. A genuine wrong planchet shows full, sharp reeds on its smaller circumference.
1967 Kennedy Half Clipped Planchet
Clipped planchet with the Blakesley Effect — the rim is weak exactly opposite the missing clip.
How to Identify
- A curved section (curved clip) or straight section (straight clip) of the coin is missing — the planchet was incomplete before striking
- Blakesley Effect: Check the rim directly opposite the clip — the rim should be weak, tapered, or fading out at that exact point. This is the key authenticator because an incomplete planchet cannot fill the collar on the opposite side
False Positives to Avoid
Post-mint damage from grinding, vise marks, or pliers. If the rim is strong and sharp directly opposite the "clip," it is almost certainly post-mint damage, not a genuine clipped planchet. Multiple clips and larger percentages missing command the higher end of the value range.
1967 Kennedy Half Dollar Traps: Common Mistakes That Cost Collectors Money
Machine Doubling (left, worthless flat shelf) vs. a true Doubled Die (right, rounded widened serif).
⚠️ Trap 1: Machine Doubling — The #1 Rejection Reason
Flat, shelf-like doubling on the date "1967," Kennedy's portrait, or lettering. The secondary image appears as a step down alongside the primary device and may look quite dramatic, especially under magnification.
During 1967's emergency production run, dies were running at maximum speed and could loosen in their chucks. Upon striking, a loose die would "chatter" or slide slightly, dragging hot metal and creating shelf-like distortions. This is extremely widespread on 1967 halves.
- The secondary image is flat and step-like — not rounded
- The secondary image makes the letter look narrower (it reduces width)
- There are no split serifs — no "V" or "tongue" shapes at serif corners
- True Doubled Dies widen and layer; Machine Doubling compresses and shelves
Value: Face value / silver melt only — $0 premium.
⚠️ Trap 2: "Whizzed" Business Strikes Sold as SMS Coins
A 1967 half with a shiny, satin-like surface being sold as an SMS coin — often listed alongside inflated FS-101 prices.
Because SMS coins command higher prices, sellers may use a high-speed wire brush or polishing wheel on a common business strike to simulate the satin finish. SMS coins also carry the exclusive FS-101 variety, making the fraud doubly profitable.
- An altered coin shows microscopic parallel grooves cut into the metal surface — visible under 20× magnification
- A genuine SMS has raised die polish lines (lines on the coin's surface from die preparation); altered coins do not
- The rim is the clearest tell: SMS rims are sharp and square; polished business strikes retain the slightly rounded, beveled rim
- For any high-value SMS candidate, third-party certification by PCGS or NGC is mandatory
Value of altered coin: Near melt only — the premium disappears with authentication.
⚠️ Trap 3: Fake "Missing Clad Layer" Coins (Acid-Dipped or Plated)
A 1967 half dollar with one copper-red face, offered as a Missing Clad Layer error at a significant premium.
Scammers dip a normal coin in acid to dissolve the silver outer layer and reveal the copper core, or they plate a coin with copper. Because genuine missing clad errors are visually dramatic, these fakes can appear convincing.
- Weigh it first: A genuine missing clad layer weighs 9.4g–10.1g. A fake or acid-dipped coin weighs ~11.5g
- Acid-dipped surfaces are pitted, rough, and show mushy or eroded detail — genuine errors have smooth metal flow on the copper side
- The rim-to-core transition on a fake is gradual or chemically irregular; on a genuine error it is sharp and mechanical
Value of fake: Face value / melt only.
1967 Kennedy Half Dollar Grading: How Condition Controls Value
Grading (assigning a numeric condition score from 1–70) has an enormous effect on 1967 Kennedy Half Dollar values — especially for the Business Strike varieties, which were handled roughly and where MS66 or MS67 examples can be single-digit population rarities.
| Grade | What It Means | FS-101 (SMS) | FS-102 / FS-103 | FS-801 |
|---|---|---|---|---|
| AU55 | About Uncirculated — slight wear on high points | N/A (SMS only) | $40–$80 | $60–$100 |
| MS63 | Choice Uncirculated — no wear, moderate marks | $300–$450 | $120–$225 | $200–$300 |
| MS65 | Gem Uncirculated — no wear, minor marks only | $600–$900 | $300–$500 | $500–$800 |
| MS66/67 | Superb Gem — exceptional strike and surface | $1,500–$3,500+ | $600–$2,100+ | $1,000–$2,500 |
⚠️ Raw vs. Certified Prices
All values above are for certified (PCGS or NGC slabbed) coins. Raw (uncertified) coins typically trade at a 30–50% discount due to authentication risk. For any Business Strike variety (FS-102, 103, 801) or SMS FS-101, professional certification is strongly recommended before selling.
The "Cameo" (CAM) and "Deep Cameo" (DCAM) designations — applied to SMS coins with frosted devices over mirrored fields — add substantial premiums on top of the grade. A DCAM specimen of the FS-101 is the apex collectible of the entire 1967 Kennedy series.
1967 Kennedy Half Dollar Authentication & When to Certify
For any 1967 Kennedy Half Dollar you believe carries a major variety or error, third-party certification by PCGS or NGC is the standard for market acceptance. Here is what to know before you submit.
💡 Before You Submit
- Do NOT clean the coin — cleaning destroys value regardless of grade
- Handle with cotton gloves — fingerprints etch into silver surfaces permanently
- Confirm the strike type (SMS vs. Business) and target variety before paying for attribution
- Weigh the coin if you suspect a planchet error — mandatory before submission
Submission Guide: Getting FS Numbers Attributed
This is a critical, often-missed step: standard grading does NOT automatically attribute Fivaz-Stanton (FS) variety numbers. Variety attribution must be requested and paid for as a separate add-on service at PCGS or NGC.
- Verify with a loupe: Confirm the pickup points (split serifs, notched stars, quadrupled TRUST) using 10×–20× magnification before paying submission fees
- Confirm strike type: Ensure the SMS vs. Business identification matches the target variety — FS-101 only on SMS; FS-102/103/801 only on Business Strikes
- Weigh planchet errors: Mandatory for Missing Clad Layer, Wrong Planchet, and Clipped Planchet submissions
- Request variety attribution: When submitting to PCGS or NGC, select the tier that includes "Variety Attribution" and add the specific FS designation as a service add-on
- Consult die markers: The die clash, specific polish lines, and stage-specific markers described above help confirm the die state and strengthen the attribution request

1967 Kennedy Half Dollar Errors — Frequently Asked Questions
Is a 1967 Kennedy Half Dollar worth anything?
Yes — every 1967 Kennedy Half Dollar contains 0.1479 troy ounces of silver, giving it a melt value of approximately $3.50–$5.00 based on current silver spot prices. That is the floor. Confirmed die varieties (FS-101, FS-102, FS-103, FS-801) and major planchet errors can push the value to hundreds or even thousands of dollars in certified grades.
How do I tell if my 1967 half is an SMS or a Business Strike?
Hold your coin under a single light and tilt it slowly. A Business Strike shows rotating "cartwheel" spokes of light caused by flow lines in the metal. An SMS coin has smooth satin or mirror-like fields with no spokes, and its rims are sharply squared off rather than rounded. This distinction is critical because the FS-101 variety exists only on SMS coins, while FS-102, FS-103, and FS-801 exist only on Business Strikes.
My 1967 half has doubling on the date — is it a valuable Doubled Die?
Probably not. Machine Doubling — a flat, shelf-like step alongside the date numerals that makes the numbers look narrower — is extremely common on 1967 halves and carries zero premium. A true Doubled Die shows rounded, split serifs that widen the letter and specific pickup points in TRUST (FS-101), IN GOD/hair (FS-102), or LIBERTY (FS-103). If the doubling looks like a step or ledge, it is Machine Doubling.
Does a 1967 Kennedy Half Dollar have a mintmark?
No — mintmarks were suspended from 1965 through 1967 to discourage coin hoarding, so all 1967 Kennedy Half Dollars (both Business Strikes and SMS issues) have no mintmark. If you find a 1967 half with a "D" or "S" mintmark, it is either a counterfeit or a coin with an altered date (for example, a 1976 half modified to read 1967).
How much silver is in a 1967 Kennedy Half Dollar?
Exactly 0.1479 troy ounces of silver — this is the 40% silver clad formula, composed of 80%/20% silver-copper outer layers bonded to a 21%/79% silver-copper core. Note this is substantially less than the 0.3617 troy ounces in a 1964 Kennedy Half (90% silver) and more than the 0 ounces in post-1970 copper-nickel coins.
Why is the SMS FS-101 so much more valuable than the Business Strike DDOs?
Two reasons: visual drama and condition. The FS-101 shows four distinct overlapping impressions (quadrupling) rather than simple doubling, making it visually spectacular. Because SMS coins were immediately packaged, they survived in higher average grades. Add a Deep Cameo (frosted devices over mirrored fields) designation and you have a rarity within a rarity — a coin that is both a rare die variety and a supreme example of SMS production at its finest.
What is the Blakesley Effect and how do I use it?
The Blakesley Effect is the key test for a genuine clipped planchet error. Because the planchet blank was punched with a section missing, the incomplete blank could not fill the coining collar on the side directly opposite the clip. This causes the rim on the opposite side to be weak, thin, or fading out. To test: locate the missing metal (the "clip"), draw an imaginary straight line across the coin, and check the rim on that opposite point. If the rim is strong there, it is post-mint damage — not a genuine clip.
Should I clean my 1967 Kennedy Half Dollar before submitting it?
Never. Cleaning a coin — even with soap and water — damages the surface in ways visible under grading-service magnification and results in a "details" or "cleaned" grade that drastically reduces market value. Grading services are trained to detect all forms of cleaning, including the most gentle polishing. Leave the coin exactly as found and let the professionals evaluate its natural surface.
