This is the PCGS Plate Coin shown on the PCGS Coinfacts website. This rare and significant variety is one of just two of the round 50 cents denomination that displays the maker’s initials FD – for Frontier, Deviercy & Co. – prominently on the obverse. The other is the nearly as rare BG-404, and the two were actually coined from the same obverse die. “7 to 9 known” provided by PCGS CoinFacts. The present piece is among the finest known. This lightly toned Choice Mint State example will be a welcome addition to another specialized cabinet. Only one other BG-403 appears in the PCGS online archives. Provenance: The Paul Deitzel Jr. Collection. You have the opportunity to change or add your name to the provenance of this very important California Fractional Gold.
