A very rare variety of late Cracow trojaks.
Variety without the last digit - only the digits 161 are visible (vintage 1618 or 1619).
An uncommon variety, unknown to both Tadeusz Iger and unlisted in the specialized catalog of "Trojaks and sixes from 1618-1627" by Nechitaylo-Ermashenko-Zamiekhovskiy.
A naturally circulated piece.
