Professional authentication (PCGS, NGC, or ANACS) is recommended for any 1984 quarter with a claimed value over $100.
Machine Doubling (flat, shelf-like doubling) is extremely common on 1984 quarters and has NO numismatic value.
Dryer coins (thick rounded rims from tumbling in commercial dryers) are Post-Mint Damage, not mint errors.
Do not submit coins worth less than the grading fee (~$30–$50). Most circulated 1984 quarters are worth only face value.
Over 1.2 billion 1984 Washington Quarters rolled off presses in Philadelphia and Denver — making them among the most common coins ever struck. Yet hidden inside that enormous mintage are genuine rarities: coins missing an entire metal layer, struck on the wrong blank, or preserved so perfectly they rival 19th-century classics in price. A 1984-P in MS67 (the highest commonly awarded grade) has sold for over $1,200 — with no error at all. This guide covers every significant error and variety, how to identify each one, and what to expect at auction.

1984 Washington Quarter Specifications & Mintage
Error identification starts with knowing what a perfect 1984 quarter looks like. Any significant deviation from these constants — without a documented mint cause — is a warning sign. A digital scale accurate to 0.01g is your single most important tool.
1984 Washington Quarter obverse showing "P" mint mark right of the ribbon, and standard reverse eagle design.
| Specification | Standard | Authentication Notes |
|---|---|---|
| Composition | Cupro-nickel clad | 91.67% copper, 8.33% nickel total. Two outer nickel layers bonded to a pure copper core — the "Johnson Sandwich." Visible copper stripe on edge confirms genuine clad planchet. |
| Weight | 5.67 grams | Acceptable range 5.44g–5.90g. Below 5.44g: likely Missing Clad Layer or Wrong Planchet. Above 6.0g: likely plated novelty or foreign-coin planchet. |
| Diameter | 24.30 mm | Exceeding 24.38mm confirms Broadstrike. Smaller than standard (e.g., 21.2mm) indicates Wrong Planchet. |
| Edge | Reeded — 119 reeds | Reeding applied by the collar die. Smooth edge on an oversized coin = Broadstrike. Smooth edge on a normal-size coin = damage or filing. |
| Obverse | Washington portrait (Flanagan) | "P" mint mark right of ribbon on Philadelphia strikes — a feature standardized only in 1980. "D" for Denver. Absence of any mint mark on a 1984 coin is suspicious; verify the mark wasn't removed. |
| Reverse | Eagle on arrows (Flanagan) | Standard business-strike reverse. "Type B" proof reverse dies were largely segregated by 1984. |
Mintage by Facility
| Mint | Mark | Type | Mintage | Notes |
|---|---|---|---|---|
| Philadelphia | P | Business | 676,545,000 | Higher die pressures → often weaker hair detail. MS67 examples extremely rare; auction records exceed $1,200. |
| Denver | D | Business | 546,483,064 | Typically sharper strikes. MS67 very rare; range $550–$780. |
| San Francisco | S | Proof only | 3,065,110 | Deep Cameo Proofs sold in annual Proof Sets. S-mint business strikes do not exist for 1984 — a business-looking S coin requires expert authentication. |

1984 Washington Quarter Quick Checks: Valuable or Not?
Run these checks in order. Tools needed: a digital scale accurate to 0.01g, a 10x magnifying loupe, and calipers. The ratio of genuine errors to damaged or misidentified coins in the 1984 quarter market is roughly 1:10,000 — these checks cut through the noise fast.
A digital scale is the first and most objective test for 1984 quarter planchet errors. 5.67g is normal; significant deviation signals an error.
✅ Valuable Checks
Check 1: Missing Clad Layer — The "Red Quarter"
Both sides of the coin. One side should be the normal silver-grey; the other a deep, lustrous copper-red (the exposed copper core).
Stark two-tone appearance plus weight of approximately 4.6g–4.9g (15–20% lighter than 5.67g). The copper side often shows slightly weaker strike detail — actually a sign of authenticity, not damage, because the thinner planchet couldn't fill the die fully.
Acid-dipped fakes (where nitric acid dissolved the nickel layer) show rough, pitted, or etched surfaces under 10x magnification and may have a reduced diameter. Environmental toning creates reddish tints but will NOT change weight. A genuine missing clad has full 24.3mm diameter and smooth, flow-lined surfaces.
Check 2: Wrong Planchet (Struck on Nickel 5¢ Blank)
Compare size to a normal quarter. A wrong-planchet coin is noticeably smaller. Also inspect the edge — there should be no copper stripe.
Weight of exactly 5.0 grams. Diameter approximately 21.2mm (vs. normal 24.3mm). Solid silver-grey edge with NO copper stripe. The full 1984 quarter design is present but peripheral lettering like "QUARTER DOLLAR" is often cut off or partial at the edges.
Filed or ground coins show tool marks on the edge. "Magician's coins" (two halves glued together) reveal a seam at the edge under 20x magnification. Plated novelty coins have uniform surfaces but incorrect weight. Genuine wrong-planchet coins have a perfectly seamless solid nickel-alloy edge.
Check 3: Doubled Die Obverse (DDO)
Under a 10x loupe: the date "1984," the motto "IN GOD WE TRUST," and the word "LIBERTY."
Split serifs — tiny notched corners on letters — and a distinct separation between a primary and secondary image. Look for a notched corner on the "4" in 1984 or the "L" in LIBERTY. The secondary image should be rounded (same relief as the primary) and the letters should appear thicker overall.
Machine Doubling (MD) — extremely common on 1984 quarters — shows a flat, shelf-like secondary image that looks smeared or pushed off the main letter. MD reduces or maintains letter width; a true DDO increases it. If the doubling is flat and shelf-like, it is MD and worth zero premium.
Check 4: Off-Center Strike or Broadstrike
Overall design placement and the edge. Off-center shifts the design to one side; broadstrike expands the coin outward with a smooth (un-reeded) edge.
Off-center: a blank crescent of unstruck planchet visible, with the date "1984" still readable (10–50% off is most valuable). Broadstrike: diameter exceeds 24.3mm, edge is smooth with no reeding, coin typically retains mint luster.
A Misaligned Die (MAD) strike shows slightly off-center design but retains a complete rim all around — low value. Off-center strikes have an incomplete rim on the blank side. Broadstrikes are easily confused with Dryer Coins (see Traps below) — the key difference is that broadstrikes are LARGER than normal.
❌ Trap Checks (Common False Alarms)
Trap: Machine Doubling — Extremely Common, Zero Value
Under 10x loupe: the date "1984" and motto "IN GOD WE TRUST."
Flat, shelf-like doubling where the secondary image looks smeared, pushed, or shaved off the main device. Letter width is reduced or unchanged. Occurs when the die shifts after the strike. Pervasive on 1984 quarters.
- Secondary image is flat (no relief of its own) — a true DDO has a rounded secondary image
- Letter appears the same width or thinner — a true DDO adds letter thickness
- Looks like something was dragged, not stamped
Trap: Dryer Coin — Post-Mint Damage, Not a Mint Error
The rim and surface. A coin trapped in a commercial dryer tumbles for hours against the drum, creating distinctive damage.
Thick, rounded rim rolling inward over the design edges. Diameter equal to or smaller than 24.3mm. Dull, polished surface with countless tiny contact marks. No radial metal flow.
- Diameter is normal or smaller — a genuine Broadstrike is LARGER than 24.3mm
- Rim is thick and rounded inward — a Broadstrike rim is flat or absent
- Surface shows tumbling abrasion — a genuine striking error retains mint luster

Condition Value Chart (Non-Error Coins)
The "hidden" value sector for 1984 quarters: brutal 1980s bulk-handling made flawless specimens almost impossible to preserve. Note the dramatic price gap between MS66 and MS67 — a coin worth $50 suddenly becomes worth $1,200. If you find a pristine 1984-P from an old mint set, weigh it carefully.
| Grade | 1984-P | 1984-D | 1984-S Proof |
|---|---|---|---|
| Circulated (G–EF) | Face value | Face value | — |
| MS63 / PR65 | $0.25–$2 | $0.25–$2 | $5–$10 |
| MS65 / PR68 | $10–$20 | $10–$20 | $12–$20 |
| MS66 / PR69 | $30–$50 | $25–$45 | $20–$30 |
| MS67 / PR70 DCAM | $430–$1,200+ | $550–$780 | $100–$160 |
Values for certified examples. MS67 rarity reflects the near-impossibility of preserving 1984 quarters through 1980s bulk distribution without bag marks on Washington's cheek or the Eagle's breast.
1984 Washington Quarter Valuable Errors: Detailed Guides
Each section below covers one major error — how it forms, exactly what to look for, common fakes, and market values. Errors are ordered by value (highest first).
Missing Clad Layer — The "Red Quarter"
Normal 1984 quarter (left) vs. Missing Clad Layer error (right) showing the exposed copper-red core on one side.
Origin & Background
The 1984 quarter uses a "clad" composition: a copper core sandwiched between two outer layers of cupro-nickel. These layers are bonded under extreme pressure during planchet strip production. If impurities or uneven pressure cause the nickel layer to fail to bond on one side, that layer may peel away before or during blanking. A blank punched from that defective strip will have nickel on one side and bare copper on the other — creating the striking "Red Quarter" collectors prize.
How to Identify
- One side is deep, lustrous copper-red; the other is standard silver-grey
- Weight is approximately 4.6g–4.9g — about 15–20% lighter than the 5.67g standard
- The copper side typically shows slightly weaker strike detail (dies couldn't exert full pressure on the thinner planchet) — this weakness is a mark of authenticity
- Full 24.3mm diameter is maintained; the coin is not shrunken
- Surfaces on the copper side should be smooth and flow-lined, with mint luster where preserved
False Positives to Avoid
Unscrupulous sellers use nitric acid to dissolve the nickel layer, creating a fake "red quarter." Test: (1) check weight — acid-dipped coins lose inconsistent amounts; (2) examine surfaces under 10x — genuine missing clad is smooth; acid damage leaves rough, pitted, or etched texture; (3) check diameter — acid eats the edge and may reduce the coin's size slightly, while a genuine error maintains full diameter. Environmental toning can also produce reddish colors but will never alter weight.
Market Values
- 🔸 Certified MS63–MS65: $200–$600
- 🔸 Raw (ungraded): typically 30–50% less
- 🔸 Higher grade or exceptional eye appeal: premiums above $600 possible
Auction Record
Heritage Auctions records show 1984-D Missing Clad Layer quarters selling in the $200–$600 range depending on grade. The 1984-D is the more commonly documented example in auction archives.
Struck on Nickel (5¢) Planchet — Off-Metal Error
A 1984 quarter design struck on a nickel (5¢) planchet (right) vs. a normal-size 1984 quarter (left), showing the dramatic size difference.
Origin & Background
This error occurs when a Jefferson Nickel planchet — intended for the 5-cent press in the same facility — accidentally falls into the hopper feeding the quarter press. The quarter dies (sized for a 24.3mm coin) strike the smaller 21.2mm nickel blank. Metal flows outward but cannot fill the larger collar, producing a coin smaller than a quarter but bearing the full (or near-full) 1984 Washington quarter design.
How to Identify
- Weight: exactly 5.0 grams (the Jefferson Nickel planchet weight)
- Diameter: approximately 21.2mm — noticeably smaller than a normal 24.3mm quarter
- Edge: solid silver-grey with NO visible copper stripe (nickel is not clad; it is a solid alloy)
- Peripheral lettering like "QUARTER DOLLAR" may be cut off or incomplete at the edges
- The date "1984" and Washington portrait should be clearly visible
False Positives to Avoid
Filed-down or ground coins show obvious tool marks on the edge under magnification. "Magician's coins" (two different-denomination halves joined) reveal a seam running through the center of the edge under 20x magnification. Plated novelty coins may look similar but will weigh incorrectly. A genuine wrong-planchet coin always has a perfectly seamless, solid edge and a weight precisely matching the intended planchet metal.
Market Values
- 🔸 Certified, date fully visible: $300–$800+
- 🔸 Mint State examples with strong details command the highest premiums
Doubled Die Obverse (DDO)
Machine Doubling (left, flat shelf) vs. true Doubled Die (right, split serifs with full relief on secondary image). Both shown at 10x magnification.
Origin & Background
In the 1980s, working dies were created by pressing a hardened hub into a die blank multiple times ("multiple-squeeze hubbing"), with an annealing (softening) step between squeezes. If the hub and die were misaligned for the second squeeze, a secondary impression was left on the die. Every coin struck by that die then shows the doubled image. For 1984, verified DDOs are typically Class II (Distorted Hub) or Class V (Pivoted Hub) — expect subtle spread, not the dramatic doubling of the 1955 Lincoln cent.
How to Identify
- Under 10x loupe: split serifs — notched corners — on letters in "IN GOD WE TRUST" or "LIBERTY"
- Look for a notched corner on the "4" in 1984, or the "L" in LIBERTY
- Both the primary and secondary images should be rounded and in full relief
- Letter thickness is increased in a true DDO; Machine Doubling maintains or reduces thickness
- The spread is typically toward the center or toward the rim (not a flat smear)
False Positives to Avoid
Machine Doubling (MD) is the single most common misidentification on 1984 quarters. MD is caused by die movement after the strike (the die drags across the already-struck coin surface) — it produces a flat, shelf-like "shadow" that appears smeared. The critical test: if the secondary image has no relief of its own (it's flat), it is MD and worth nothing. If the secondary image is rounded with full depth, it is a genuine DDO.
Market Values
- 🔸 Certified MS63–MS65: $50–$150
- 🔸 Higher grades or more dramatic spread will command premiums within that range
Off-Center Strike
A 1984 quarter off-center strike at approximately 30%, showing the blank crescent with the date "1984" still fully visible — the critical value factor.
Origin & Background
An off-center strike occurs when the planchet is not properly centered under the dies at the moment of strike. The result: a blank crescent of unstruck metal on one side, and a partial or full design on the rest of the coin. The rim is incomplete on the struck side. These are genuine mechanical failures, not post-mint alterations.
How to Identify
- Visible blank crescent of unstruck planchet on one side of the coin
- Rim is incomplete or missing on the offset side (a Misaligned Die has a complete rim)
- The date "1984" must be visible for full attribution value — without the date, the coin becomes a generic clad-era Washington error worth significantly less
- Value scales with percentage off-center: 10–20% with date = $15–$90 certified; 25–50% with date = $40–$180 certified; 50%+ without date = $10–$60 as generic
False Positives to Avoid
A Misaligned Die (MAD) coin looks slightly off-center but retains a complete rim all the way around — low value. A 1–5% off-center strike is essentially face value; the cost of grading exceeds any premium. Only meaningful off-center strikes (10%+) with the date visible justify authentication costs.
Market Values
- 🔸 10–20% off-center, date visible, certified MS63–MS65: $60–$90
- 🔸 25–50% off-center, date visible, certified MS63–MS65: $100–$180
- 🔸 50%+ off-center, no date: $10–$60 (generic Washington error)
Broadstrike (Struck Without Collar)
Broadstrike (left) — expanded diameter, smooth edge, radial metal flow — vs. Dryer Coin (right) — normal size, thick inward rim, tumbling abrasion.
Origin & Background
The "collar die" is the steel ring that surrounds the planchet during striking, containing the metal and imparting the reeded edge. If the collar fails to rise into position, the planchet is struck without containment — the metal flows freely outward, creating a coin larger than standard with a smooth, un-reeded edge. This is a Broadstrike.
How to Identify
- Diameter exceeds the standard 24.3mm — measure with calipers to confirm
- Edge is smooth with no reeding (the collar die never engaged)
- Metal has flowed radially outward from the strike center
- Design is usually centered but may appear spread or slightly flattened
- Surface typically retains mint luster
- A Partial Collar ("Railroad Rim" — half reeded, half smooth) is worth $15–$40
False Positives to Avoid
The Dryer Coin is the most common Broadstrike impostor. Key differences: Broadstrikes are LARGER than normal (metal flowed outward). Dryer Coins are normal-size or slightly smaller (metal was beaten inward). Broadstrikes have smooth, radially expanded edges; Dryer Coins have thick, rounded rims with tumbling abrasion. These are metallurgical opposites.
Market Values
- 🔸 Centered Broadstrike, certified: $30–$60
- 🔸 Uncentered Broadstrike, certified: $25–$50
- 🔸 Partial Collar (Railroad Rim), certified: $15–$40
Double Struck & Clipped Planchet Errors
A double-struck 1984 quarter showing two distinct, overlapping Washington quarter impressions. Note the blended design elements in the overlap zone.
Double Struck
A double-struck coin is struck by the dies twice, producing two distinct overlapping impressions of the 1984 Washington quarter design. The second strike is often rotated or off-center relative to the first, creating a dramatically dramatic "double image." Both impressions should show equal depth and detail consistent with die contact. The overlap area will show blended or confused design elements. A "flip-over" double strike (coin flips between strikes) is even more valuable. Machine Doubling cannot replicate this — MD shows only a flat shadow, not two complete independent impressions. Certified value: $200–$500+.
Clipped planchet showing the curved crescent missing from the edge and the weak (Blakesley Effect) rim area directly opposite the clip.
Clipped Planchet
A clipped planchet has a crescent-shaped "bite" missing from the coin's edge, created when the blank was punched from a strip that overlapped a previous punch hole. The Blakesley Effect must be present to confirm authenticity: a weak or missing rim area directly opposite the clip, caused by insufficient metal flow during the upsetting mill step. Without the Blakesley Effect, the missing area is almost certainly post-mint damage (pliers, cutting tool). Certified value: $25–$75.
Spitting Eagle (Die Clash)
Reverse of a 1984 quarter showing the Spitting Eagle die clash — a raised line extending from the eagle's open beak, caused by die-on-die impact.
Origin & Background
A die clash occurs when the feeder mechanism fails to load a planchet between strikes, and the obverse and reverse dies slam directly into each other. The outline of Washington's neck and jaw is transferred onto the reverse die, and the eagle's wings are transferred to the obverse die. On 1983 and 1984 quarters, Washington's neck line often lands near the eagle's beak — creating the illusion the eagle is "spitting."
How to Identify
- A raised vertical line extends from the Eagle's open beak downward toward the wing or shoulder on the reverse
- The line must be raised (metal flowed into the die's clash impression) — not incuse
- Under magnification, raised die-clash marks have rounded profiles; scratches have sharp V-shaped profiles
Market Reality
Despite its memorable name and heavy eBay marketing, the Spitting Eagle is a common die event, not a major variety. Seasoned numismatists value it at $5–$25 raw. Grading fees ($30–$50) routinely exceed the coin's market value — do not submit for certification unless the clash is exceptionally heavy and well-preserved.
1984 Washington Quarter Traps: Common Damage Mistaken for Errors
For every genuine 1984 quarter error on the market, there are thousands of damaged, altered, or misidentified coins. These three traps account for the overwhelming majority of false positives.
⚠️ Machine Doubling (MD) — The Most Common 1984 Trap
Under a loupe, the date or motto letters appear doubled — but the secondary image is flat and shelf-like, with no real depth. Looks like something was smeared or dragged sideways.
The die shifts slightly after the strike, dragging across the already-struck metal surface. This is a mechanical press failure, not a die-creation error. It was pervasive on high-speed 1980s presses.
- Secondary image has no relief — it's flat, like a shadow stamped into the surface
- Letters appear the same width or narrower (true DDO makes letters thicker)
- The doubling looks "smeared" or "pushed," not stamped
Value: Face value only. Zero numismatic premium. Do not submit for grading.
⚠️ Dryer Coin — Post-Mint Damage (PMD)
Thick, rounded rim that rolls inward over the design edges. Diameter is normal or slightly smaller than standard. Coin surface is dull and polished with countless tiny contact marks.
A coin trapped in a commercial dryer's fin tumbles for hours against the drum. Heat and repeated impacts upset the rim, rolling it inward. The tumbling polishes the surface smooth. This is purely post-mint damage.
- Diameter is normal or smaller — a genuine Broadstrike is LARGER than 24.3mm
- Rim is thick and rolls inward — a Broadstrike rim is flat or absent, never thickened
- Surface shows abrasion/tumbling — a Broadstrike retains mint luster
Value: Face value only. Post-Mint Damage cannot be certified as an error.
⚠️ Acid-Dipped Fake — Counterfeit Missing Clad Layer
A coin with one copper-red side that appears to mimic a Missing Clad Layer error. Sometimes sold online as genuine errors at inflated prices.
Sellers use nitric acid to dissolve the outer nickel layer, exposing the copper core. The result looks superficially like a genuine error but fails every physical test.
- Weight: genuine missing clad weighs 4.6g–4.9g consistently; acid coins lose irregular amounts
- Surface texture (10x loupe): genuine error has smooth, flow-lined surfaces; acid damage leaves rough, pitted, or etched texture
- Diameter: acid eats the edge — genuine errors maintain full 24.3mm; acid coins may be slightly reduced at the rim
Value: Face value only if altered. Altered coins cannot be certified as genuine errors by any TPG.
1984 Washington Quarter Grading: How Condition Affects Value
Grade is assigned on the 70-point Sheldon scale. For 1984 quarters, grade is everything — a one-point difference at the top of the scale means hundreds of dollars.
The primary grading focus points for Washington Quarters are:
- Washington's cheek: The first area to show wear and the first to collect bag marks from bulk handling. MS67 requires a virtually mark-free cheek.
- Hair above the ear: High relief details that flatten quickly with circulation. Fully separated strands = Uncirculated. Flat area = circulated.
- Eagle's breast feathers: Focal point where contact marks concentrate from the reverse side of bagged coins.
⚠️ The MS67 Trap
The dramatic value jump from MS66 ($30–$50) to MS67 ($430–$1,200+) for the 1984-P tempts many collectors to over-submit coins that are actually MS65 or MS66. Only submit genuinely exceptional, mark-free, blast-white examples. The grading fee (~$30–$50) on a coin that grades MS65 is a net loss.
For error coins, grade still matters significantly: a Missing Clad Layer in MS65 commands a premium over the same error in MS63. However, for major errors (Missing Clad, Wrong Planchet), even circulated certified examples retain meaningful collector value because the error itself is the rarity.
1984 Washington Quarter Authentication: When and How to Get Certified
For any 1984 quarter with a claimed value over $100, certification by a recognized third-party grading service (TPG) is mandatory for full market liquidity and protection against fraud.
The Three Recognized TPGs
- PCGS (Professional Coin Grading Service) — most widely recognized, highest resale premiums
- NGC (Numismatic Guaranty Company) — equally recognized, strong auction records
- ANACS — widely accepted, typically lower fees, good for mid-tier errors
Submission Rules
| Coin Type | Submit? | Reason |
|---|---|---|
| Missing Clad Layer | Yes | Value ($200–$600) far exceeds grading fee |
| Wrong Planchet | Yes | High-value error; certification essential for sale |
| MS67 candidate | Yes | Value ($430–$1,200+) justifies fee if grade confirmed |
| Off-Center (10%+, date visible) | Yes | Certified versions sell for significantly more than raw |
| DDO, Broadstrike, Clipped | Maybe | Only if value estimate clearly exceeds grading fee |
| Spitting Eagle, MS65 or below | No | Grading fee ($30–$50) exceeds market value |
💡 Pre-Submission Protocol
Before submitting any coin: (1) Do NOT clean it — even light cleaning destroys numismatic value permanently. (2) Photograph both sides under good lighting. (3) Weigh the coin. (4) Measure the diameter. (5) Post to a reputable coin forum for a second opinion before paying grading fees.
Dealer referral information is not included in this guide. For local coin dealers, consult the Professional Numismatists Guild (PNG) directory or attend a regional coin show.
1984 Washington Quarter Errors: Frequently Asked Questions
Is a 1984 quarter with a "P" mint mark normal?
Yes. Philadelphia began placing the "P" mint mark on quarters in 1980. All Philadelphia quarters from 1980 onward have a "P" to the right of Washington's ribbon. Some collectors confuse the 1984-P with pre-1980 Philadelphia coins (which had no mint mark) — if someone tells you a 1984 "No P" quarter is rare, they are either confused about the year or attempting a scam.
How do I check if my 1984 quarter has a Missing Clad Layer?
Two-step check: First, look at both sides — one should be copper-red (core exposed) and the other normal silver. Second, weigh it — the coin should be approximately 4.6g–4.9g (normal is 5.67g). If both conditions are met, seek professional authentication. Do not clean the coin.
My 1984 quarter looks doubled. How do I know if it's a real DDO or Machine Doubling?
Look under a 10x loupe. If the secondary image is flat (no real depth, looks smeared or pushed off the main letter) — it is Machine Doubling, worth nothing. If the secondary image is rounded, has full depth (relief), and creates split serifs (notched letter corners), it is a genuine Doubled Die. Machine Doubling is extremely common on 1984 quarters; true DDOs are not.
Why is a perfect (MS67) 1984 quarter worth over $1,000 with no error?
In the 1980s, the U.S. Mint prioritized volume over quality. Coins were ejected at high speed into metal bags, causing immediate contact marks on the high points (Washington's cheek, Eagle's breast). Finding a 1984-P with a virtually mark-free cheek — required for MS67 — is extraordinarily rare despite the 676 million-coin mintage. Extreme scarcity at the top grade creates extreme value.
What's the difference between a Broadstrike and a Dryer Coin?
They are metallurgical opposites. A Broadstrike (genuine mint error) was struck without a collar die — the metal flowed outward, making the coin larger than 24.3mm with a smooth, un-reeded edge. A Dryer Coin (post-mint damage) was beaten in a tumbling commercial dryer — the metal was forced inward, producing a normal-size or smaller coin with a thick, rounded rim and abrasion marks. Measure the diameter first — if it's bigger than normal, you may have a Broadstrike.
Should I submit my 1984 Spitting Eagle quarter for grading?
In most cases, no. The Spitting Eagle die clash typically sells for $5–$25 in raw (ungraded) condition. Standard grading fees run $30–$50, meaning you would lose money on certification. The exception: if your example shows an unusually heavy clash, exceptional preservation, and you already have a buyer willing to pay a premium for a certified example.
Does the 1984-S quarter ever appear as a business strike?
No — the San Francisco Mint produced only Proof quarters in 1984 (3,065,110 pieces sold in annual Proof Sets). If you have a coin with an "S" mint mark that looks like a business strike, verify the mint mark was not added or altered. An S-mint business strike in 1984 would be extraordinarily unusual and should be professionally authenticated before any claims are made.
How much is a 1984 quarter with no mint mark worth?
This is almost certainly a Philadelphia coin where the "P" mint mark is just worn, weakly struck, or being viewed at an incorrect angle. In 1984, all Philadelphia business-strike quarters had the "P" mint mark. A genuine 1984 quarter without any mint mark would be extraordinarily unusual — look very carefully under a loupe at the area to the right of the ribbon before drawing any conclusions.
