Denier - Geoffrey

Geoffrey IV of Brittany held Nantes only briefly — his county was contested almost continuously, and the mint operated under conditions of political instability that kept production runs short. The narrow two-year window attributed to this issue reflects a specific phase of Geoffrey's control over the city before broader Breton dynastic pressures reasserted themselves.

PA#244 is among the scarcer feudal deniers of the Loire region, with surviving examples typically showing uneven billon alloy distribution across the flan.
