FROM MY ORIGINAL CASE DIRECTLY FROM THE US MINT.  The 2025 S US Mint Proof Set Clad includes 10 uncirculated coins with a mixed denomination, all made of clad composition. This set is struck in proof quality at the San Francisco Mint, certified by the U.S. Mint, and includes THE LAST Lincoln Penny Cent. The set comes in a complete box with a Certificate of Authenticity, making it a valuable collector's item for those interested in United States coins and mint sets.
