Vintém of João I

The Vintém of João I was one of the earliest Portuguese coins struck in bronze, a practical shift from silver that allowed for wider circulation among common folk during his reign.

This denomination, introduced under the Aviz dynasty, featured a simple cross on the obverse, symbolizing the king's alliance with the church and state. Weighing around 2 grams, it was designed for everyday transactions, from buying bread to paying taxes. We know it was produced in Lisbon, though exact minting techniques remain debated among historians.

Records of the Vintém's production are scarce; much was likely lost in later fires or wars. That said, surviving examples show wear from heavy use, suggesting they were anything but rare in their time.

Some call it the poor man's coin, which, in a way, it was—proving that even kings understood the value of small change.
