Aragonese Florin

The Aragonese Florin was one of the earliest European coins to mimic the exact weight and purity of the Florentine florin, weighing in at about 3.5 grams of pure gold to ensure seamless trade across borders. This wasn't some accidental copy; it was a calculated move by the Crown of Aragon to plug into international commerce, starting around 1284. For over two centuries, these coins flowed from mints in places like Barcelona and Valencia.

They were struck on planchets of refined gold, often sourced from local mines or trade imports, though exact origins for many batches remain murky—records from that era are as scarce as hen's teeth. I’ve handled dozens over the years, and the designs vary: early ones feature a cross and the Aragonese arms, later ones might show a king’s bust. Myths about hidden treasures? Overblown. Most ended up in circulation, not buried hoards.

One oddity: the coin's edge sometimes shows file marks from quality checks, a detail that fools rookies into thinking it's been tampered with. As for numbers, mintage figures? Lost to time, probably in some medieval fire.
