Kopeck - Mikhail I оМ оБ

Mikhail I, the first Romanov tsar, inherited a treasury gutted by the Time of Troubles — fifteen years of civil war, foreign occupation, and dynastic collapse that left the Russian monetary system in fragments. These wire-cut kopecks, struck by hammer between hand-cut dies at the Moscow mint, were produced under a regime still consolidating legitimacy as much as territory. The mint marks оМ and оБ denote Moscow and an individual die-cutter's mark respectively, part of a rudimentary accountability system that is still not fully decoded by scholars.
