1935 1 Peso Argentina

The 1935 1 Peso from Argentina was the first in its denomination to employ an aluminum-bronze alloy, a cost-saving measure during the global economic slump.

This coin was struck at the Casa de Moneda in Buenos Aires. Its obverse bore the Argentine coat of arms, complete with the sun of May, while the reverse showed a simple wreath. Production continued through 1951 with minor design tweaks, reflecting post-war adjustments.

Exact mintage numbers remain elusive. Archives from the period suffered losses, possibly in bureaucratic reshuffles.

Those who handle these coins know they're sturdy, but not indestructible—I've seen more than one worn smooth from pocket change.
