| Additional information |
The trzeciak — a denomination equal to three denarii — was introduced under Sigismund I as part of a broader monetary reform driven by the chronic shortage of small silver in circulation across the Polish Crown. Kraków's mint, operating under royal supervision throughout this period, produced the coin across nearly two decades with subtle die variations that Kopicki catalogues across three sequential reference numbers, each reflecting typological shifts rather than dramatic redesigns.
Sigismund's monetary legislation of 1526 standardized Polish coinage in response to the flooding of markets with debased foreign issues, particularly from Silesia and Prussia.
