Rare 1966 Washington Quarter Error Coin- Could It Be Worth $20 Million?

The 1966 Washington Quarter has garnered attention in numismatic circles, with rumors suggesting that certain error coins from this year could be worth up to $20 million

While such claims are largely unverified, the 1966 quarter does hold significant value for collectors, especially those with rare errors or in exceptional condition.​

Historical Context: The 1966 Quarter

In 1966, the U.S. Mint was transitioning from silver to a copper-nickel clad composition for quarters. This change aimed to address coin shortages and reduce production costs. 

Notably, from 1965 to 1967, the Mint removed all mint marks to discourage hoarding by collectors. As a result, all 1966 quarters lack a mint mark, regardless of their mint of origin.​

Notable Error Types in 1966 Quarters

Error coins are highly sought after due to their rarity and uniqueness. Some of the notable error types found in 1966 Washington Quarters include:​

  • Doubled Die Reverse (DDR): This error occurs when the coin’s reverse design is struck twice, slightly offset, leading to a noticeable doubling effect.​
  • Off-Center Strikes: These coins are misaligned during striking, resulting in a portion of the design missing.​
  • Clipped Planchets: A portion of the coin’s edge is missing due to a mishap during the blanking process.​
  • Struck on Wrong Planchet: Occasionally, a quarter design is struck on a planchet intended for another denomination, leading to size and weight anomalies.
  • Missing Clad Layer: These coins are missing the outer nickel layer, exposing the copper core and giving the coin a distinct appearance.​
