Groat - Martin I Barcelona

Martin I inherited the Crown of Aragon in 1396 following the extinction of the direct Catalan male line through his brother John I, who died without a legitimate male heir. His reign coincided with the Aragonese intervention in Sicily and Sardinia, and the Barcelona mint sustained active production to fund those campaigns. The groat series under Martin continued the high-silver standard established by his predecessors — .917 fineness held firm even as Castilian coinage was being debased across the same decades.

Cru#513 is well-documented but not particularly rare in worn grades. Sharper survivors are less common, largely because these circulated hard throughout the Crown's Mediterranean trading network.
