5 Pesos

By 1965, Uruguay was deep into a decade-long inflationary spiral that would eventually see the peso lose the overwhelming majority of its value before the currency was replaced by the new peso in 1975 at a conversion rate of 1,000 to 1. Coins of this denomination were minted because they still technically functioned, but purchasing power was eroding fast enough that the public treated metal coinage as an inconvenience rather than a store of value.

KM#47 continued a series that had been running since 1965, sharing its alloy with other circulating issues of the period as Uruguay leaned on aluminium bronze for durability in coins that saw heavy, rapid turnover.
