Kopeck - Mikhail I Pskov, ПС

Pskov mint wire money from the reign of Mikhail Romanov, the dynasty's reluctant first tsar — elected at sixteen after the Time of Troubles had devastated both the population and the monetary system. The ПС mintmark distinguishes Pskov production from the Moscow and Novgorod issues of the same decade, a distinction that matters for provenance but was invisible to most contemporary users of these fish-scale slivers.
