Among the most notable are the rare Bicentennial quarters and certain rare dimes, each valued at an astonishing $22 million.
The United States Bicentennial quarter, minted in 1975 and 1976, commemorates the 200th anniversary of the nation’s independence.
These quarters feature a unique design with a Colonial drummer on the reverse and the dual date “1776–1976” on the obverse.
The key to the $22 million valuation of these particular Bicentennial quarters lies in their rarity and condition.
For example, a few Bicentennial quarters with striking errors or unique die varieties are highly sought after.
While dimes are generally small in size and value, their historical and numismatic significance can elevate their worth considerably.
Out of the 24 originally minted, only a handful are known to exist today, making the 1894-S Barber Dime one of the most sought-after coins in the world.
