Crown of Aragon Corona of Peter IV

Peter IV's Corona stands out for its use in funding the Aragonese navy during the War of the Two Pedros, a conflict that dragged on for years and likely kept the mints busy.

Weighing around 3.5 grams of gold, this coin was struck in Barcelona using metal from uncertain sources—perhaps Catalan mines, though records from that era are as reliable as a sieve. The obverse typically bore the king's effigy, a nod to his authority, while the reverse featured the Aragonese arms, all crammed onto a small flan that must have challenged the engravers.

One oddity: despite its royal ties, the Corona sometimes turned up in hoards as far as Italy, suggesting it traveled more than Peter IV himself did. Mintage figures? Lost to time, probably in some archive fire. As for myths about its curse—I've heard them all, and they're as tired as I am after three decades of debunking.
