1/2 Céntimo Pattern

Peru's decimal coinage reform of the 1850s required extensive pattern trials before any new denomination entered production. This half-céntimo piece was part of that experimental phase — the denomination itself was ultimately never adopted for circulation, making the pattern series the only physical evidence that the denomination was ever seriously considered. KM#Pn6 is one of several copper trials from 1855 attributable to this reform push, likely struck at limited numbers for official review.
