Among these coveted treasures are the Bicentennial Quarters, issued in 1976 to commemorate the 200th anniversary of the United States' independence.
While many of these quarters entered circulation, a select few are now among the rarest and most valuable coins in existence, fetching staggering prices at auctions.
The Bicentennial Quarters hold a special place in American numismatic history.
The obverse side continues to showcase George Washington, as with all quarters issued since 1932.
What makes certain Bicentennial Quarters exceedingly rare and valuable is primarily due to minting errors or variations that occurred during production.
Among these, the most renowned is the 1976-D Bicentennial Quarter struck on a copper-nickel clad planchet intended for dimes.
This error resulted in a quarter that is approximately the size of a dime but bears the distinctive Bicentennial design.
