1 Farthing - Henry III Dublin

Henry III's Irish farthing issue of the early 1250s was struck to address the chronic shortage of small-denomination silver in circulation across the Lordship of Ireland. Cut halfpennies and farthings — literally quartered pennies — had served as the practical substitute for decades, but their irregular weights and shapes made commerce increasingly difficult. The Dublin mint's production of round farthings was a deliberate administrative intervention, not simply a monetary convenience.

Surviving examples are exceptionally rare. At 0.28g, losses to corrosion, hoarding, and the simple attrition of handling have claimed the vast majority of the original output.
