Denga - Ivan IV Tver

Ivan IV was proclaimed Grand Prince at age three in 1533, making the monetary decisions of this period the work of regents — first his mother Elena Glinskaya, then a succession of boyar factions who essentially ran the treasury between her death in 1538 and Ivan's assumption of real power. Elena's monetary reform of 1535 standardized coinage across Muscovite territories, and Tver, absorbed into Moscow decades earlier, continued issuing dengi under its own regional designation as part of that administrative settlement rather than any genuine local autonomy.
