Denga - Ivan IV ДЕ

Ivan IV — Ivan the Terrible — standardized Russian wire money coinage through a sweeping monetary reform beginning in 1535, years before he formally assumed the title of Tsar. The denga denomination sat below the kopek, with two denga equaling one kopek. Production involved hammering flat thin silver wire and striking individual blanks, which accounts for the irregular, often elongated planchet shapes characteristic of the type.

The ДЕ inscription abbreviates the mint city of Pskov, one of several regional mints operating under centralized weight and fineness standards during this reign.
