Mint Silver Proof Set includes a collection of silver coins struck in proof finish at the San Francisco Mint. This set comes in its original mint box with a certificate of authenticity from the U. With a fineness of 0.9, these uncirculated coins are a valuable addition to any collection of United States coins. The coins pictured are the coins you are purchasing. These coins are from my personal collection. If you are interested, I have many other coins for sale.
