The star attraction is a Bicentennial Quarter that sold for nearly $501K USD. Struck in 40% silver and in flawless condition, this coin is prized for its historical significance and mint state.
Valued over $25K, the Double Die Obverse Quarter is a result of a minting error that caused the design to be stamped twice, creating a noticeable doubling effect on the date and motto.
An off-center strike error, where the coin blank is misaligned in the press, can make an ordinary quarter worth over $25K. The more dramatic the misalignment, the higher the value.
Some Bicentennial Quarters were mistakenly struck on 40% silver planchets meant for collector sets. These silver composition error quarters are highly prized, with values exceeding $25K in top term.
The Full Drum Lines Quarter, identifiable by its detailed reverse drum design, can fetch over $25K. This indicates an early strike from a fresh die, adding to its rarity and value.
Overstruck quarters, minted over previously struck coins or different denominations, are extremely rare. These unique anomalies are valued at over $25K due to their minting errors.
Proof quarters are crafted with care for a mirrored finish, but errors like smudged designs or incorrect metals can occur. Bicentennial proof errors can elevate a quarter's value to over $25K.
