A distinct minting error is the reason why a particular Bicentennial Quarter is so valuable.
A prized possession for any collector, the 1932-D Washington Quarter is estimated to be worth more than $20,000.
Collectors regard the 1913 Liberty Head Nickel as one of their most prized coins.
The greatest prices are paid for this quarter in pristine condition, as collectors vie for specimens that have withstood the test of time.
An additional treasure, the 1943-S Silver Washington Quarter is valued at more than $20,000.
