15 Kopecks 15 orbits

This coin's informal name — "15 kopeks, 15 orbits" — refers to the price of a ride on the Moscow Metro, which held at 15 kopeks from 1961 until the fare system collapsed with the Soviet economy itself. The stability was deliberate political theater: subsidized transit prices were a cornerstone of Soviet social policy, and raising them would have amounted to an admission that the planned economy was failing.

The thirty-year production run with virtually no design change reflects the same logic — monetary stasis as ideological statement.
