1/2 Florin - Alfonso V

Alfonso V of Aragon — "the Magnanimous" — held Majorca as part of his Aragonese inheritance while spending the bulk of his reign pursuing and eventually securing the Kingdom of Naples, which he conquered in 1442. He governed from Naples thereafter and never returned to Iberia. The island's mint continued striking fractional gold under his name throughout those decades, largely to service local Mediterranean trade rather than any administrative initiative from the king himself.

The half florin denomination tracks directly to the Florentine florin standard, adopted across the Crown of Aragon in the 14th century to facilitate commerce with Italian merchants.
