Bicentennial Quarters with the "S" mint mark (San Francisco Mint) are often more valuable, especially the silver-clad varieties. Silver-clad Bicentennial Quarters contain 40% silver, making them more valuable than the standard copper-nickel versions.
Like all collectible coins, the value of a Bicentennial Quarter increases with its condition. Coins graded MS65 or higher can be more valuable, with the highest grades fetching higher prices.
Certain rare varieties, like those with doubled die errors, can be more valuable. However, these are rare and typically confirmed by professional grading services.
The design of the Bicentennial Quarter is unique, featuring a colonial drummer on the reverse, which adds to its collectible appeal.
A vast number of Bicentennial Quarters were produced, which generally keeps their value close to face value unless they have unique attributes as mentioned above.
All Bicentennial coins were minted with the dual date 1776-1976. They were actually minted in 1975 and 1976, but no coins bear the 1975 date.
