1 Gulden - Charles V

This joint emission from the three IJssel cities — Deventer, Kampen, and Zwolle — was authorized under Charles V's imperial monetary ordinances as the Habsburg administration pushed to rationalize the chaotic patchwork of local coinage across the Low Countries. The three cities retained nominal minting rights as imperial cities but operated under increasingly tight imperial supervision throughout the 1530s.

Frédéric's reference number places it within a small documented group; Delmonte's attribution confirms the type as a collaborative issue, a minting arrangement unusual enough that surviving examples are rarely encountered outside specialist sales.
