Rijksdaalder

Friesland maintained its own mint at Leeuwarden throughout the seventeenth century, stubbornly exercising provincial minting rights even as the Dutch Republic's central authorities repeatedly pushed for standardization. The Rijksdaalder was the workhorse of large-denomination silver in the Baltic trade, moving grain, timber, and naval stores between Amsterdam and the ports of Danzig and Riga in quantities that made these coins as familiar in Poland as in the Netherlands.

The sixty-year production window reflected continuous demand rather than interrupted minting — Frisian issues were never purely local currency.
