1 Pierreale - Federico III d'Aragona

Federico III ruled Sicily in defiance of papal and Angevin pressure following the War of the Sicilian Vespers, which had begun in 1282 with the massacre of French troops across the island. The Pierreale — named for its obverse type derived from the earlier Carlin of Charles I — became the backbone of Sicilian commercial silver through his long reign, struck across a span of four decades as the kingdom maintained its stubborn independence from Naples.

MIR 184 encompasses considerable die variation across that production window. Dating individual pieces within the 1296–1337 range without documentary provenance is essentially impossible.
