Kopeck - Michael I Velikiy Novgorod, НRGI

Michael I's reign opened with Russia still clawing out of the Time of Troubles, and Novgorod presented a particular complication: Swedish forces had occupied the city since 1611 and only returned it under the Treaty of Stolbovo in 1617. Minting at Novgorod resumed almost immediately after reoccupation, making the earliest issues of this decade inseparable from the politics of that handover. The НRGI designation identifies the mint signature specific to this Novgorod production, distinguishing it from the concurrent Moscow and Pskov wire-money output of the same reign.
