Denga - Dmitry Donskoy Kolomna countermarked

Dmitry Donskoy's coinage presents one of the earliest uses of Cyrillic inscription on Muscovite coins, introduced at a moment when the principality was asserting itself against Mongol suzerainty — most dramatically at Kulikovo Field in 1380. The Kolomna countermark on this denga reflects the fragmentary, workshop-based nature of early Muscovite minting, where host coins were overstruck or stamped to validate them within a specific territorial authority rather than produced uniformly from a single facility.

HPF#111 is among the rarer catalogued countermark applications in the Donskoy series.
