Real of Duarte

Duarte's real was struck using silver from Portuguese mines, a practical move to fund his kingdom's ventures during a time of economic flux.

That silver came from regions like Alentejo, where local deposits helped stabilize the currency after years of inconsistent minting. The coin itself featured the Portuguese coat of arms on one side and a cross on the other, reflecting the era's blend of royal authority and religious symbolism. Weighing around 3.5 grams, it represented a step toward standardization, though records of exact production volumes vanished in the 1755 Lisbon earthquake.

Minting occurred in Lisbon, with possible variations from other sites, but evidence is sparse. For a scholar-king, Duarte kept designs straightforward—no elaborate flourishes, just the essentials.

It's a coin that outlasts its maker; enthusiasts note how such pieces often turn up in hoards, a quiet irony in their persistence.
