The Bicentennial Quarter is part of a special series of coins minted to commemorate the 200th anniversary of the United States.
Released between 1975 and 1976, these coins include distinctive designs for the quarter, half dollar, and dollar.
The quarter, in particular, features a colonial drummer on the reverse side, replacing the traditional eagle, while the obverse retains the familiar profile of George Washington.
The Bicentennial Quarters were struck in both copper-nickel clad and a special 40% silver composition, with the latter intended primarily for collectors.
The notion of a Bicentennial Quarter worth $40 million might sound like a myth, but it's rooted in the realities of numismatic rarities and the potential value of certain error coins.
Another valuable error type is the off-center strike, where the design is not properly centered on the coin.
Additionally, there are the rare instances of coins struck on the wrong planchet (the metal disc that becomes a coin), which can also lead to significant value increases.
