Penning - Conrad of Swabia Deventer

Conrad of Swabia served as Bishop of Utrecht from 1076 until his death in 1099, a tenure defined almost entirely by the Investiture Controversy. He was a committed imperialist who sided with Henry IV against Gregory VII, and Utrecht's mint operated under that political alignment throughout. The Deventer mint, one of several episcopal minting rights Utrecht held east of the IJssel, produced these lightweight pennies for regional exchange in the lower Rhine and Overijssel trade networks.

The Ilisch reference places this firmly within a documented die sequence for the type.
