The 1980 Washington Quarter Value Guide

A wrong planchet error occurs when a blank intended for a different coin denomination inadvertently enters the quarter press and receives a full strike with Washington quarter dies. In the 1980-D case, a five-cent nickel planchet — softer, lighter, and smaller — received the full quarter design. This is arguably the most dramatic error on the entire 1980 quarter error list, because the result is visually and physically different from every normal coin that left Denver that year.

The key diagnostic is weight and edge. A normal quarter weighs 5.67 grams; a coin struck on a nickel planchet weighs approximately 5.00 grams. The edge will lack the copper-colored stripe that is normally visible on clad coinage, since the nickel planchet has no copper core layer. The design will appear slightly compressed toward the rim, and the coin's diameter is measurably smaller than the standard 24.30 mm. Any deviation in these physical parameters is grounds for immediate professional authentication.

The only publicly documented 1980 wrong-planchet quarter was authenticated and graded MS-61 by ANACS, carrying a documented value of $180 at that grade. Comparable wrong-planchet errors on other Washington quarter dates have sold at Heritage Auctions in the range of $5,000–$15,000+ for higher-grade certified examples. Certification by PCGS or NGC is essential before any sale, as this error is a known target for counterfeiting. Never clean, alter, or weigh a suspected example without first consulting a professional numismatist.

The 1980-D Doubled Die Reverse FS-801 is a catalogued die variety that originated during the hub-pressing stage of die manufacture at the Denver Mint. When a master hub impresses its design into a working die, a slight positional shift between hubbing cycles creates duplicate design elements with three-dimensional depth. Every coin subsequently struck from that die carries the same doubling — making this a true collectible variety, not a random striking accident.

The doubling on this variety appears on the reverse legends, most prominently on "UNITED STATES OF AMERICA" and "QUARTER DOLLAR." Under a 10× loupe, look for notched, split serifs where the secondary letter image is rounded and additive — visibly thicker letters with a stepped secondary edge. The eagle's wing tips and tail feathers may also show slight secondary imaging. The critical distinction from worthless machine doubling is that true hub doubling shows a rounded, three-dimensional secondary image rather than a flat, shelf-like shadow lying to one side.

This variety is catalogued in the Cherrypickers' Guide to Rare Die Varieties under designation FS-801, confirming its status as a recognized, collectible hub-doubling variety exclusive to the Denver Mint. Values range from $15–$30 in circulated grades where serifs retain their notching, up to $200–$250 or more in gem Mint State. Heritage Auctions has recorded MS-66 examples with FS-801 attribution above $200, representing a meaningful premium over a common 1980-D in that grade.

An off-center strike occurs when a planchet feeds into the coining press slightly out of position, so the dies do not strike the center of the blank. The result is a coin where the design is shifted toward one side, leaving a crescent-shaped arc of plain, unstruck metal on the opposite edge. At the Denver and Philadelphia Mints in 1980, automated high-speed production presses occasionally allowed a misaligned planchet to pass through before the mechanical feed could correct it.

The degree of misalignment is expressed as a percentage: a 10% off-center strike means 10% of the planchet area is blank, while a 50% strike leaves half the coin bare. The most critical diagnostic is whether the date digits remain fully visible — because the date confirms authenticity and year attribution, and collectors will not pay full premiums for an off-center coin that is missing its date. Examine the blank crescent for tool marks or post-mint damage that might mimic this error; a genuine off-center will show a smooth, clean planchet surface in the unstruck area.

Value scales directly with the degree of misalignment and date visibility. A 10–20% off-center 1980 quarter typically brings $20–$50. Coins shifted 50% or more with a clearly legible 1980 date can reach $250–$380 or above in high grades. A dramatic off-center at 85% graded MS-65 was offered at GreatCollections in November 2025, demonstrating that high-grade, high-percentage examples still attract strong bidding interest even among common-date modern quarters.

A broadstrike error results when a coin is struck outside the retaining collar die that normally constrains the planchet during striking. The collar serves two functions: it holds the blank at the correct diameter and impresses the reeded edge pattern. When the collar is absent or fails to deploy correctly, the metal spreads outward freely under the striking pressure, producing a coin that is wider and thinner than standard — and entirely without rim reeding.

Broadstruck 1980 quarters are easy to distinguish from normal examples: the diameter is measurably larger than the standard 24.30 mm, the edge is completely smooth and flat rather than ridged, and the coin may appear slightly thinner or show a weakly defined design near the outer edges where metal spread beyond the normal die coverage area. Importantly, broadstrikes weigh close to the standard 5.67 grams because no metal is lost — only redistributed — distinguishing this error from a wrong-planchet coin where weight differs significantly.

An ICG-graded MS-64 broadstrike 1980 quarter sold for $211.56, establishing a clear market reference for this error type in mid-mint-state grades. Circulated examples with post-mint damage typically bring $40–$60; high-grade certified pieces with full luster can reach $150–$215. The PCGS and NGC populations for broadstruck 1980 quarters are modest, suggesting these errors were largely spent or discarded by the public before entering collector hands.

A Repunched Mint Mark (RPM) occurs when the mintmark punch was applied to the working die more than once at slightly different positions. Before modern computer-controlled manufacturing, individual mint mark punches were manually struck into each working die. A slight rotation or lateral shift between impressions left a ghost secondary mintmark impression behind, and every coin struck from that die carried the same doubled or shifted mint mark — a permanent die characteristic, not a per-coin accident.

On 1980-D quarters, RPM varieties have been documented where the "D" shows a secondary "D" image shifted slightly to the north or southeast of the primary mark. To identify this variety, examine the area directly around the "D" mintmark on the obverse — located to the right of Washington's ponytail ribbon — under a 10× loupe. The secondary impression will appear as a faint but distinct additional "D" outline, partially overlapping or adjacent to the main punch. Distinguish from die wear by confirming that the secondary image retains the curved shape of the letter "D" rather than being an amorphous smear.

RPM varieties on modern clad quarters are more modest in value than their silver-era counterparts, but they are genuine collectible die varieties that attract specialist collectors. Circulated 1980-D RPM examples typically bring $10–$20 over face value; Mint State examples in the MS-63 to MS-65 range can reach $25–$75, particularly when the RPM shift is dramatic and clearly visible. These varieties are best authenticated and catalogued by comparing to documented die-variety resources such as the Cherrypickers' Guide or CONECA's listings.

A die break is a progressive fracture in the steel coin die that develops from accumulated stress during high-volume production runs. As millions of strikes travel through the press, dies endure repeated high-pressure impacts that eventually cause micro-fractures in the die face. When a fracture develops, metal from the planchet flows into the crack during each subsequent strike, leaving a raised line, ridge, or lump on struck coins. A cud — the most prized form of this error — forms when a section of the die breaks off completely at the rim, leaving a raised, featureless blob where the missing die piece can no longer imprint any design.

Die breaks and cuds on 1980 quarters have been documented on both obverse and reverse. A standard die break appears as a raised irregular line running across part of the coin's design or field. A cud is specifically located at the rim, where the raised lump meets the coin's edge — creating a visually distinctive "bump" that is unmistakably different from post-mint damage. Inspect the rim area under magnification: genuine cuds have a clean, featureless flat top with no design elements, while the transition from normal design to the blank cud area is abrupt.

Values for 1980 quarter die breaks depend on the size, position, and drama of the break. Minor internal die breaks with a small raised line typically bring $25–$50 over face value. Large rim cuds — especially those covering significant lettering or spanning more than 5–8% of the coin's circumference — can reach $100–$150 or more in Mint State grades. The larger and more visually dramatic the cud, the more desirable it becomes to error coin specialists, who prize dramatic examples as showpieces for their collections.
