Mexico ^[MX]

Standard circulation coinage of the United Mexican States (1993-present)

The standard circulating coinage of the United Mexican States before the onset of hyperinflation. Introduced in 1970, this series features large-format copper-nickel coins, most notably the iconic 1 Peso bearing the portrait of revolutionary leader José María Morelos. It includes various fractional Sentavo denominations alongside majestic depictions of indigenous Aztec rulers and historical icons.

A major transitional coinage series triggered by the severe economic crisis of the early 1980s. To curb soaring production costs, the Bank of Mexico executed a drastic metallic reform in 1984. All existing denominations were downsized; the famous 1 Peso Morelos was shrunk into a lightweight stainless steel coin, while mid-value coins shifted to cost-effective aluminum-bronze alloys.
