The Valuable 1998 Washington Quarter Errors (Complete Guide)
Despite mintages in the hundreds of millions, the 1998 Washington Quarter produced some genuinely dramatic mint errors. Mechanical failures at the press — misaligned planchets, die collar malfunctions, doubled-hub impressions, and wrong-metal incidents — each tell a different story and command a very different price at auction. Here are the five most important error types to know, ranked and explained.
A double-struck error occurs when a coin is not ejected from the press after the first blow and receives one or more additional strikes. In 1998, several Philadelphia Mint quarters survived the press experiencing two, three, or even four full impressions from the dies.
Visual identification is straightforward: look for a second, partially overlapping image of Washington's portrait on the obverse and/or a second eagle impression on the reverse. The more off-center the second strike — and the greater the angular rotation between impacts — the more visually dramatic and desirable the error becomes to collectors.
These errors command the highest premiums in the 1998 series because they are mechanical spectacles. A 1998-P triple-struck example graded MS-67 realized $1,080 at auction in October 2021. A 1998-P quadruple-struck piece in MS-65 brought $1,140 at Heritage Auctions. Double strikes with the second image significantly off-center have sold in the $840 – $960 range at Heritage.
An off-center strike results when a planchet is fed into the press misaligned, causing the die to strike it off-center. The degree of misalignment ranges from a subtle 5–10% shift (barely noticeable) to a dramatic 80–90% displacement where most of the planchet remains blank.
To identify an off-center 1998 quarter, look for a crescent-shaped area of flat, unstrucked planchet metal on one side of the coin, with the complete design compressed into the remaining struck portion. The reeded edge will be incomplete or missing entirely on the open side. Collector preference heavily favors coins where the date remains clearly readable despite the displacement.
Values range widely based on displacement percentage and grade. A minor 15% off-center 1998-P in MS-66 sold for $67 in 2022. A 75% off-center 1998-D brought $139 the same year. A dramatic 50%+ off-center 1998-P in MS-65 realized $2,040 — making it the most expensive off-center 1998 quarter on public record. The strong collector demand for dramatic misalignments on this final-year design drives these premiums.
Doubled die errors on the 1998 Washington Quarter occur when the working die receives multiple, slightly misaligned impressions from the hub during the die-making process. The resulting die then imprints that doubling onto every coin it strikes. Unlike double strikes, the doubling on a true doubled die is baked permanently into the die itself.
On the 1998 DDO, look for spread or notching on the motto "IN GOD WE TRUST," the date digits, or Washington's profile details on the obverse. The DDR variety shows doubling on reverse lettering such as "UNITED STATES OF AMERICA" or "QUARTER DOLLAR." Under a 10× loupe with raking side-illumination, a true doubled die shows distinct, stepped letter serifs or rounded doubling — not a mechanical doubling "shelf" from bag damage.
Collectors have long valued 1998 doubled die varieties as accessible entry-level errors that can be found in roll hunting. Circulated examples typically bring $50 to $150 depending on the strength of the doubling, while uncirculated pieces with dramatic spread can reach $300 to $400 or more. The key is finding strong hub doubling rather than the common machine doubling that has no collector premium.
A missing clad layer error occurs when a planchet is delivered to the mint already missing one of its outer copper-nickel bonding layers. Since modern clad quarters are made of a copper core sandwiched between two copper-nickel outer layers, removing one of those outer layers exposes the warm, reddish-brown copper core beneath. The resulting coin is visually striking — one side appears normal while the other glows a distinctly different color.
Identifying a genuine missing clad layer is straightforward but requires attention to color and weight. A normal 1998 quarter weighs 5.67 grams; a coin with a fully missing clad layer will weigh noticeably less, around 5.0–5.3 grams depending on which layer is absent. The exposed side shows the copper core in its natural state — no design was struck into a missing layer, so the surface may be relatively smooth or show soft, mushy design detail on the affected side.
Collectors prize missing clad layer quarters because the error originates before the coin ever reaches the press — it is a planchet-preparation defect, not a striking anomaly. Values depend on whether the missing layer is a full or partial absence and which side is affected. Full single-layer missing examples have sold in the $150–$500 range, with exceptional pieces or those in gem mint state reaching higher.
A broadstrike error occurs when the retaining collar — the ring die that confines the planchet during striking and creates the reeded edge — is missing or fails to engage properly. Without the collar constraining the metal, the planchet spreads outward under the force of the press blow, creating a coin measurably wider in diameter than a standard 1998 quarter's 24.3 mm.
A broadstruck 1998 quarter is visually distinctive: the coin is physically larger than normal, the reeded edge is absent or only partially formed, and the design elements near the rim may appear slightly stretched or spread outward. The lettering around the perimeter — "LIBERTY," "IN GOD WE TRUST," "UNITED STATES OF AMERICA" — may touch or merge with the rim area. Despite the striking irregularity, the full design is usually present and legible.
Broadstrikes are relatively accessible errors that appeal to beginning error collectors because they are easy to identify and present well in a collection. Values depend on the severity of the collar escape and the grade. Modest examples in circulated grades bring $30–$60, while attractive uncirculated broadstrikes with full design detail and good eye appeal can reach $100–$200 or more. The 1998 series broadstruck examples have appeared in both Heritage and eBay auction records.
