Uruguay
Republic copper Proof Pattern Doblon 1870 Proof Details (Altered Color) NGC, KM-Pn31. A very scarce copper pattern which was created in preparation for the issuance of the Doblon, a denomination which was never actually produced for circulation. This pattern is rightfully considered one of the elusive rarities of the Uruguayan numismatic series. Almost matte on the reverse, with an obverse showing approximately 60% tone (similar to reverse) and approximately 40% mint red color.
