I have owned since they were new. This United States Bicentennial Silver Proof Set from 1976 S is a must-have for any coin collector. The set includes a variety of silver coins that are all in uncirculated condition. The coins were struck in San Francisco and have a fineness of 0.9. They have a 40% silver content. Each coin is beautifully composed of silver and has a proof strike type, making them incredibly shiny and well-maintained. The set comes with certification from the U. Mint, adding to its value and authenticity. Don’t miss your chance to add this rare and valuable set to your collection.
