1 Schilling - Sigismund III Vasa Riga

Sigismund III Vasa claimed the Polish throne in 1587 and the Swedish throne in 1592, making Riga — then a city of the Polish-Lithuanian Commonwealth — a minting point caught between competing dynastic ambitions. His eventual deposition from Sweden in 1599 did nothing to interrupt Riga's output; the city continued striking under his Polish authority for decades. The billon schilling was the workhorse denomination of Baltic trade commerce, circulating across Livonia, Prussia, and into Muscovite markets.

The thirty-five year production window for this type means die varieties are numerous and chronological attribution within the series remains contested among specialists.
