Soviet 1925 15 Kopeks

What surprises many is that the 1925 Soviet 15 kopeks coin was struck from aluminum bronze, a makeshift alloy born of the regime's copper shortages in the mid-1920s.

That material reflected the era's pragmatism. The Soviets had just emerged from civil war, and every scrap counted. This coin, with its simple design of a hammer and sickle encircled by wheat, was produced at the Leningrad Mint. Records suggest it circulated widely in the NEP period, when limited capitalism eased the economy's collapse.

We don't know the exact mintage figures; those archives were likely purged or lost in later upheavals. What we can say is that survivors often show wear from heavy use in rural markets.

Planchets for these coins might have been recycled from pre-revolutionary stock, though that's unconfirmed.
