Spain authorized Cuba to counterstamp circulating foreign silver with a key punch — the symbol of Havana — to legitimize coins already in widespread use across the island. The practice was a fiscal stopgap, not a reform: rather than mint new coinage for the colony, Madrid simply validated what merchants were already accepting. Pieces bearing this mark passed through official channels after stamping, though the host coins themselves span multiple issuing nations and dates.
The key counterstamp is notoriously inconsistent in placement and depth, a product of hand-applied dies across different customs posts.
