Victoria Proof Florin 1853 PR66 Cameo NGC, Royal mint, KM746.1, S-3891. Of the 11 examples graded by both PCGS, this is the single second-highest graded example, but the only piece to receive any sort of "Cameo" designation. Well-frosted devices, contrasted with lustrous fields and good amounts of multi-hued iridescence give this coin great eye appeal. Quite an exceptional piece, and surely among the finest extant!
