1 Groat - Edward IV Light cross coinage, Drogheda

Edward IV's "light coinage" reform of 1460 reduced the weight standard for Irish silver in a deliberate attempt to curb the chronic outflow of coin to England, where heavier Irish pieces were being melted for profit. Drogheda operated as one of the principal Irish mints of the period, alongside Dublin and Waterford, though its output was substantially smaller. The cross-and-pellets reverse type is consistent across the Irish light coinage mints, but Drogheda pieces are distinguished by mint signature and are meaningfully scarcer than their Dublin counterparts.

Spink 6341 is among the more difficult attributions in late medieval Irish numismatics, with mint identification often depending on a single letter.
