1 oz Silver Bar - San Diego Zoo (U.S. Silver Corporation)

---

In 1973, the U.S. Silver Corporation struck a commemorative silver bar honoring one of the most celebrated wildlife institutions in the world. This piece of mid-century Americana captures a specific moment in the history of the San Diego Zoo, marking its legacy from 1916 through 1973. Crafted from one troy ounce of 0.999 fine silver, the bar serves as a tangible tribute to decades of wildlife conservation and public education. The front of the bar features a detailed artistic display of various animals, celebrating the institution's reputation as the world's largest. It bears the prominent inscription "San Diego Zoo" alongside "WORLD'S LARGEST" and the commemorative years "1916 to 1973". This design reflects the era's appreciation for nature and the growing global prominence of the California sanctuary. On the reverse, the issuing entity is clearly identified. The crisp lettering names the "UNITED STATES SILVER CORPORATION" and confirms the bar's physical specifications, reading "ONE TROY OUNCE" and "0.999 FINE". This side of the bar emphasizes the purity and origin of the metal, balancing the illustrative artistry of the front with clean, official mint markings.
