Pedro II bronzed Pattern 20 Reis 1860 XF (flaking), cf. KM-Pn88 (in copper), LMB-E047 (same). 28mm. 12.60gm. A most unusual rendition of this rare pattern, apparently listed only in copper, though the present specimen appears to be bronzed over some sort of dark-colored metal, possibly lead. Very rare.
