Costa Rica
Republic white-metal Proof Pattern Onza 1850-JB PR60 NGC, San Jose mint, KM-Pn3. A truly thrilling representative of this sought-after Pattern type and one that rarely comes to market with any regularity; seemingly the last instance was an SP62 we offered in 2016 as part of the Pura Vida Collection. Expertly engraved devices protrude from the white-metal canvas upon illumination, revealing impressive depth and composition. A must-have for the Costa Rican collection as one of only two currently certified by NGC.
