1/2 Groot - Arnoud van Egmond

Arnoud van Egmond's long and turbulent tenure as Duke of Guelders was marked by near-constant dynastic conflict, including the extraordinary episode in which his own son Adolf had him imprisoned from 1465 to 1471 — a filial coup that briefly paralyzed ducal administration. Coinage continued under both claimants during this period, creating attribution headaches that survive to the present day.

The van den Chijs reference places this type firmly within Guelders' mid-15th century billon and silver issues, a series complicated by irregular mint output across Nijmegen, Arnhem, and Harderwijk.
