John of Bavaria never actually ruled Holland — he was elected as administrator in 1417 following the death of William VI, holding the county in a custodial capacity while the succession dispute between the Hooks and the Cods factions ground on. His copper duit issues were struck under that contested authority, which may explain why the series is relatively short-lived. John died in January 1425 without legitimate heirs, and Holland passed to Jacoba of Bavaria, his niece, whose own claim had been the very source of the factional war he'd been brought in to manage.
