The 1976-S Bicentennial Silver Proof Set includes three coins: the Bicentennial Quarter, Half Dollar, and Dollar, all minted in 40% silver.
These coins were struck at the San Francisco Mint and were part of the United States Bicentennial celebration, commemorating the 200th anniversary of the Declaration of Independence.
The Bicentennial Quarter features a special reverse design depicting a colonial drummer boy.
It's worth noting that while the regular circulating quarters of that year were not made of silver, these proof coins were produced in 40% silver as part of special collector sets.
The value of a 1976-S Bicentennial Silver Proof Set can vary depending on factors such as its condition, rarity, and current demand among collectors.
These sets are generally sought after by numismatists due to their historical significance and silver content.
