This 1978 Washington Quarter is a certified mint error coin graded AU58 by Professional Coin Grading Service (PCGS). What makes this piece especially collectible is its dramatic 20% off-center strike, a striking mint error that occurred during the coin’s production process.
The off-center strike results in a visibly shifted design, with part of the coin blank and the remaining design sharply detailed—creating a unique and eye-catching appearance. Errors of this magnitude are highly sought after by collectors due to their rarity and the insight they provide into the minting process.
Graded About Uncirculated 58 (AU58), this coin retains strong detail with only slight wear on the highest points, preserving much of its original luster and visual appeal. The combination of high grade and a significant mint error makes this a standout piece for both error coin collectors and enthusiasts of modern U.S. coinage.
Featuring George Washington on the obverse, this quarter is part of the long-running Washington Quarter series, one of the most recognizable coins in American history. Its unusual strike elevates it from a common coin to a rare and desirable collectible.
