Interesting fact
The Tostão coin was minted during the reign of King João III of Portugal, who ruled from 1521 to 1557. The coin's design features the king's crowned bust on one side and the Portuguese coat of arms on the other. The coin was minted in the city of Porto, which was an important center of trade and commerce in northern Portugal during that time. The use of silver in the coin's minting process was a significant innovation, as it helped to increase the coin's durability and resistance to wear and tear, making it a popular choice for everyday transactions.
