1851 San Francisco State of California $5 Die Trial. K-2a. Rarity-7-. Copper. Reeded Edge. MS-64 RB (PCGS).Deep chocolate brown centers yield to faded and deepened mint orange around the peripheries. Frosty in texture with underlying luster and plenty of eye appeal. The strike is deep and crisp and the surfaces are completely undisturbed by any marks of substance; this one certainly holds up well to careful magnified scrutiny. The companion piece to the gilt silver impression from these dies offered above, and the only example of the San Francisco State of California $5 die trial in copper certified by PCGS in any grade. Lovely!From the Samuel J. Berngard Collection.
