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.
