Interesting fact

One interesting fact about this coin is that it was minted during the reign of King João III of Portugal, who ruled from 1521 to 1557. The coin features a shield with 9 or 10 castles, which represents the king's coat of arms and symbolizes his power and authority. The use of silver in the coin's minting process also signifies the value and wealth of the Portuguese Empire during this time period.
