1981 Soviet 10 Kopeks

What surprises many is that the 1981 Soviet 10 Kopeks was minted from zinc, a cost-cutting move during the USSR's economic strains that led to coins corroding faster than anticipated. This zinc composition, introduced for circulation coins like this one, reflected the era's material shortages without the glitz of earlier metals.

Weighing in at about 1.8 grams and measuring 17.5 millimeters across, it features a simple design: the Soviet state emblem on the obverse and the denomination on the reverse, all struck at the Leningrad Mint. Variations are rare; most examples show the standard reeded edge. Mintage figures for that year remain unclear, as Soviet records weren't always meticulous.

Handling these, I've seen how zinc's reactivity turns shiny new coins into dull relics over decades. It's no wonder they didn't last like their copper-nickel predecessors.
