There were many bicentennial coins issued to commemorate the 200th anniversary of the founding of the United States of America. In order to give an estimate of the value of any one of them it is...
if it has a D by George Washingtons wig, ony 25 cents. if it has nothing b the wig, still only 25 cents. if there is a S by it, it is worth about $10.
None of the bicentennial coins regardless of denomination released into circulation are worth more than face value.
Only a very high grade Mint State coin would be worth more than 25 cents. If you found it in change, just spend it.
