Republic Proof 50 Centesimos 1916 PR61 Cameo NGC, Buenos Aires mint, KM22. Lightly toned Proof with needle sharp details– as befits the technical designation – and the expected surface handling marks at this level. Only the second noticed Proof example of this type by the cataloger, apparently unlisted in all references and obviously very rare in this presentation.
Estimate: 1500-2000 USD
