Interesting fact

One interesting fact about the Tostão "P-O" – João III (3rd type, Porto) ND (1555-1557) coin from Portugal is that it was minted during a time of great change in the country. King João III, who ruled from 1521 to 1557, implemented a number of reforms aimed at modernizing Portugal and increasing its global influence. This coin, which features an image of the king on one side and the Portuguese coat of arms on the other, was likely used in everyday transactions during this time of transformation. Despite its age, the coin remains a valuable piece of numismatic history, with some examples selling for thousands of dollars at auction.
