Jefimok Rouble - Alexey Mikhailovich Countermarked over 'Erfurt Taler'

The jefimok policy of 1655 was a fiscal emergency measure: Russia lacked the infrastructure to mint silver coinage at scale, so Alexey Mikhailovich's government simply counterstamped Western European thalers already in circulation and declared them legal tender at 64 kopecks. The Erfurt taler was among dozens of host types pressed into service this way. A dated rectangular counterstamp and a horseman punch were applied together — both required for validity.

The experiment lasted a single year. Debasement controversies and commercial resistance, culminating in the Copper Riots of 1662, ultimately traced their roots back to this period of monetary improvisation.
