Trojak / 3 Grosze - Sigismund III Vasa Poznań, Lewart shield

Sigismund III Vasa's trojak coinage of 1600–1601 was produced at the Poznań mint under the direction of Kasper Rymer, one of several leaseholders who operated Polish provincial mints under contract during this period. The Lewart shield — the arms of the Firlej family — appears here not as royal heraldry but as the personal mark of the mint's then-patron, a reminder that much of the Commonwealth's small-denomination silver was effectively a private enterprise operating under royal license.

The Ig references place this among the early catalogued varieties of Poznań trojaks, a series notorious among specialists for its die inconsistencies and the sheer number of obverse and reverse combinations that emerged from what was clearly a loosely supervised operation.
