2019 Smithsonian National Zoo Commemorative Buffalo at the Castle 1 oz Silver Medal NGC PF70 Ultra C

The 2019 Smithsonian National Zoo Commemorative “Buffalo at the Castle” silver medal is a beautifully crafted private issue honoring the iconic American bison and the historic Smithsonian National Zoo. Struck in 1 troy ounce of .999 fine silver, this medal features a detailed obverse portrait of President Theodore Roosevelt, a key figure in American conservation efforts, alongside the inscription referencing the Smithsonian National Zoological Park. The reverse showcases a powerful depiction of an American buffalo standing atop rugged terrain, with stylized rays and a sun motif in the background, symbolizing the natural beauty and preservation of wildlife in the United States. The artistic design blends realism with modern engraving techniques, creating strong visual contrast and depth.

This example is certified PF70 Ultra Cameo by NGC, representing a flawless proof strike with deeply mirrored fields and frosted design elements that enhance the overall appearance. As a private issue associated with the Smithsonian Institution, it holds both numismatic and historical appeal, particularly for collectors interested in wildlife, conservation, and American heritage themes. The medal measures approximately 38.1 mm in diameter with a thickness typical of one-ounce silver issues and carries no legal tender denomination, as it is a commemorative medal rather than a coin. Its exceptional grade, attractive design, and thematic significance make it a desirable addition to specialized silver collections.
