1 Groat - Robert III Heavy Coinage, 2nd Issue

Robert III's heavy coinage takes its name from the relatively high silver content maintained during his reign, a deliberate policy response to the chronic bullion shortages and coin clipping that had plagued Scottish currency through much of the 14th century. The 2nd issue is distinguished from the 1st primarily by mintmark differences and subtle legend variations — Spink 5170 specifically places it within the Edinburgh and Perth mint output of the period.

Robert III was largely incapacitated by injury for much of his reign, with effective governance handled by his brother Robert, Duke of Albany. The groat circulated during one of the more administratively chaotic periods in Scottish regal history.
