Republic white-metal Specimen Pattern 1/2 Peso 1850-JB SP64 PCGS, London mint, KM-Pn1. Choice Mint State with fully reflective and lustrous surfaces and razor sharp details, as expected for a Proof or Specimen striking. Only trivial surface scuffing marks on the reverse prevent the Gem technical designation yet a most impressive example of this elusive and iconic unadopted pattern issue. Very rare in this elite quality, among the very finest seen by the cataloguer and most desirable as such.
