The 1792-2017-P American Liberty US Mint 225th Anniversary One Ounce Proof Silver Medal, designed by Justin Kunz and Chris Costello, was specially minted in 2017. This set of American Liberty US Mint 225th Anniversary Medals include two Proof 70 examples, one Mint State 70 example, and one stunning Specimen Proof 70. The medal celebrates the 225th Anniversary of the US Mint, which was established by the Coinage Act of April 2, 1792. Each medal in this set bears a unique finish and mint mark of the respective United States Mint facility where it was produced. The San Francisco Mint struck the standard Proof example, the Philadelphia Mint struck the stunning Reverse Proof example, the Denver Mint struck the Uncirculated example, and West Point Mint struck the Enhanced Uncirculated example. Only 16,000 of these sets are available from their initial mintage of 50,000, and less than 20% have been graded Perfect Proof 70. This is a rare second chance to add this historic set to your numismatic collection.
