Republic copper Proof Pattern 10 Centavos 1870 P-CT PR63 Brown NGC, Potosi mint, KM-X2a (previously KM-Pn2A). A choice specimen of this rare pattern, now thought to have been struck at the Potosi mint, by Clemente Torretti, very eye-appealing with substantial hints of red remaining under the brown color noted on the insert. Quite desirable in this lofty preservation.
