2019-S American Eagle One Ounce Silver "Enhanced Reverse" Proof Coin CONFIRMED. Minted at the San Francisco Mint. The 2019 American Eagle One Ounce Silver Enhanced Reverse Proof Coin is the perfect gift for any occasion or addition to any collection. A standard reverse proof coin is one featuring an "inverted" proof finish. The background is frosted, while the design elements are polished to a mirror-like finish, creating a magnificent contrast.This enhanced reverse proof coin has the same frosted background as a reverse proof coin, but what sets it apart are the multiple polished and frosted finishes applied to different isolated design elements. The selective polishing and frosting dramatically enhances the visual impact of the design. The obverse (heads) features Adolph A. Weinman's full-length figure of Liberty in full stride, enveloped in folds of the flag, with her right hand extended and branches of laurel and oak in her left. The reverse (tails) features a heraldic eagle with shield, an olive branch in the right talon and arrows in the left. Each coin bears the "S" mint mark reflecting its striking at the San Francisco Mint and is packaged in a blue velvet, satin-lined presentation case, which is placed in a classic outer blue box and accompanied by a numbered Certificate of Authenticity. The number on each Certificate of Authenticity does not reflect the order in which each coin was minted. (31.103 grams)Edge:ReededMint and Mint Mark:San Francisco - S.
