MOST VALUABLE
2010 Quarter Clipped Planchet Error
$50 – $1,100+
A clipped planchet occurs when the metal strip feeding into the coining press overlaps a hole left by the previous planchet punch, resulting in a coin with a curved or straight section physically missing from its edge. The 2010 series produced documented examples of both curved clips (the most common type) and, less frequently, straight clips caused by a misaligned punch cutting across a flat portion of the strip.
Visually, the error produces a clearly identifiable crescent-shaped or straight bite out of the coin's circumference. Collectors should also examine the opposite side from the clip for the "Blakesley Effect" — a region where the rim and nearby design elements appear noticeably weak or absent due to metal flow disruption during the strike. Presence of the Blakesley Effect is a key authenticity indicator that distinguishes genuine clipped planchets from damaged or filed coins.
The 2010-D Mount Hood quarter with a prominent curved clip graded MS65 realized $1,100 at a 2022 auction — the highest confirmed sale for any 2010 quarter error and one of the strongest results for any America the Beautiful error coin. Collector demand is driven by the dramatic visual impact and the relative difficulty of finding such examples in true Mint State condition, since the edge weakness often leads to contact marks during handling.
MOST FAMOUS
2010 Quarter Die Crack Error
$100 – $1,040+
Die crack errors form when the hardened steel working die develops hairline fractures under the immense pressure of striking hundreds of thousands of coins. Metal flows into these fractures during each strike, transferring as raised, irregular lines across the coin's surface. On the 2010 America the Beautiful series, die cracks have been documented on both the obverse Washington portrait and the reverse national park designs, with the most valuable examples running prominently across Washington's portrait or face.
The diagnostic feature is the raised, jagged line running across the coin's design — unlike a scratch or post-mint damage, die cracks are always raised above the coin's surface because they represent metal that filled the crack in the die. Under a 10× loupe, the crack line will follow the die's stress fracture pattern, which typically runs from a high-pressure point (such as the rim or a lettering serif) across the field.
Heritage Auctions sold a 2010-D Arkansas Hot Springs quarter graded MS63 bearing a large die crack across Washington's portrait for $1,040 — one of the most publicized 2010 quarter error sales. The cracking pattern — described by one dealer as making Washington appear to be "sneezing" — added novelty appeal on top of the numismatic premium. Smaller, less dramatic die cracks on lower-grade examples still fetch $100 to $300 depending on visibility and coin grade.
RAREST
2010 Quarter Doubled Die Error (DDO/DDR)
$50 – $705+
A doubled die error results from a misalignment during the hubbing process, where the working die receives multiple impressions from the master hub at slightly different positions or rotations. Each element struck into the die from the offset hub produces a slight secondary image, visible on the finished coin as doubling of design elements, lettering, or the date. On 2010 America the Beautiful quarters, both obverse doubled die (DDO) and reverse doubled die (DDR) varieties have been documented and confirmed by collectors and grading services.
The most sought-after 2010 doubled die is found on Grand Canyon quarters from the Denver Mint, where doubling appears on the reverse design elements. A separate DDR variety has been noted on some 2010 Hot Springs quarters, where doubling shows on the reverse legends. Inspect the lettering of "UNITED STATES OF AMERICA," "QUARTER DOLLAR," and "IN GOD WE TRUST" under a 10× loupe — doubled die separation will appear as distinct secondary lines, not the blurry die deterioration doubling (DDD) that is far less valuable.
GreatCollections sold a 2010-D Grand Canyon quarter graded MS65 with a confirmed doubled die error for $705 in 2020, making it one of the best-documented high-grade doubled die sales in the series. Values for doubled die 2010 quarters range from $50 to $150 for Hot Springs DDR examples depending on grade, and $200 to $705+ for the more prominent Grand Canyon DDO/DDR in MS65 and above. True doubled die must be distinguished from machine doubling, which shows flat shelf-like doubling with no collector premium.
BEST KEPT SECRET
2010 Quarter Rim Cud Error
$50 – $620+
A rim cud forms when a substantial piece breaks away from the hardened working die, leaving a recessed void in the die's surface near or at the rim. When that damaged die strikes a planchet, metal flows freely into the void, producing a raised, irregular, and completely formless blob along the coin's edge — entirely devoid of design detail. On the 2010 America the Beautiful series, rim cuds have appeared on Hot Springs and other designs, with the largest examples commanding the strongest premiums from error collectors.
The key visual feature is the blob's complete absence of design — a genuine rim cud shows only flat, raised metal at the die-break location, sharply contrasting with the surrounding struck design. The size of the cud is directly correlated with collector value: small, barely-visible cuds add a modest premium, while large cuds spanning several millimeters of the rim attract bidding competition at major auction venues. Under a 10× loupe, inspect the interior edge of the cud for a clean break line where the die metal fractured.
A 2010-P Hot Springs quarter graded MS60 bearing a prominent rim cud realized $620 on eBay — one of the highest collector-to-collector sales documented for this error type on the 2010 series. The value spread between small and large cuds is wide: minor die chip cuds at the rim may bring $50 to $100, while large, visually dramatic examples in uncirculated condition routinely break $400. The Hot Springs design is the most frequently reported host coin for this variety.
MOST ACCESSIBLE
2010 Quarter Grease Struck-Through Error
$20 – $532+
A grease struck-through error occurs when lubricating grease, die polish residue, or another foreign substance accumulates in a recess of the working die and is not cleared before striking. When the die contacts the planchet, the foreign material acts as a barrier between die and metal, preventing full detail transfer in the affected area. On 2010 quarters, grease struck-through errors have been documented across multiple designs and mints, producing coins with noticeably weakened or entirely missing design elements — lettering, portrait detail, or park scenery — in otherwise normal-looking coins.
The visual signature of a genuine grease struck-through is a soft, featureless "flat" zone within an otherwise fully struck coin. Unlike a worn area, the surrounding metal retains full mint luster, and the weak area has smooth, not abraded, surfaces. On the obverse, grease typically shows as missing or weak hair detail on Washington's portrait or absence of lettering. On the reverse, it may obscure portions of the park design. The 2010 Yosemite California issue has yielded the most publicized grease struck-through examples.
A 2010-P Yosemite quarter graded MS62 with a grease struck-through error sold for $532 on eBay, confirming meaningful collector demand even for this more common error type. Heritage Auctions sold a 2010-P Yosemite quarter graded MS60 with obverse die chip errors for $400. Lower-grade examples or those with subtle grease effects trade for $20 to $75, while dramatic examples in MS62 or better — especially those with large affected zones — can push well past $400. The accessibility of this error type makes it ideal for beginning error collectors.
