Dziesięciotalar koronny - Sigismund III Vasa Bydgoszcz mint

The 10-thaler denomination was effectively a prestige strike — produced not for commerce but for diplomatic gifts and court presentation. Sigismund III was an aggressive patron of large-module coinage, partly to assert Polish dynastic ambitions in Sweden, a throne he had lost in 1599 but never formally relinquished. The Bydgoszcz mint, operating under lease arrangements common to Commonwealth monetary administration, was one of the few facilities capable of handling the die pressure required for such a heavy flan.

Kop. 1449 is among the rarest entries in Kopicki's catalogue for this reign.
