Comment

The "Secret symbols" are small marks at any part of the coin that, we believe, are to identify the "fornaça"(Team maker) or (and) the metal composition. There are more than 200 different marks known.

Interesting fact

One interesting fact about this coin is that it was issued during the reign of King João I of Portugal, who ruled from 1385 to 1433. This coin was part of a series of coins issued during his reign to help stabilize the Portuguese economy, which had been struggling due to the effects of the Black Death and other factors. Despite being made of a relatively low-value material like billon, the coin still features a impressive level of craftsmanship and attention to detail, reflecting the artistic and cultural achievements of the time.
