Styca - Wigmund

Wigmund held the See of York during a period of acute Northumbrian political instability, with Viking raids intensifying along the northern and eastern coasts and the kingdom's royal succession collapsing into a succession of short-lived, often violently deposed kings. The archbishops of York issued their own stycas independently of royal authority, and Wigmund's coins are among the better-documented ecclesiastical issues of the series — though the copper alloy used across all late Northumbrian stycas had by this period degraded so far from the original silver content that these functioned essentially as base-metal tokens.

The series is notorious for die-cutter inconsistency and the proliferation of moneyers whose names appear across multiple reigns, complicating precise attribution.
