1/5 Libra Trade Coinage

The Peruvian libra was pegged to the British sovereign at exact parity — same fineness, same alloy, fractional weights proportionally scaled — making it one of the few Latin American gold series designed explicitly for international trade acceptance rather than domestic accounting. The 1/5 libra, at 1.6 g, mirrors the British half-sovereign's fractional logic applied to a fifth denomination. Production continued sporadically through 1969, long after Peru had abandoned the libra as legal tender, purely to supply the collector and bullion export market.
