A mule in the Fukien machine-struck cash series — almost certainly the product of a die pairing error at the Foochow mint during a period when the province was running multiple denominations simultaneously. The Qing provincial mints of this era operated with limited oversight from Beijing, and clerical or mechanical mismatches between obverse and reverse dies were rarely caught before a run had already commenced. Pn10 designation places this firmly in pattern or trial territory, though the line between sanctioned trial and production accident at Foochow is not always clean.
