Interesting fact

One interesting fact about the Standard circulation coin Real of 10 soldos - João I (Big disk; Porto) ND (1385-1397) from Portugal made of Billon weighing 2.7 g 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 standardize the currency and promote trade throughout the country. The coin's design features the king's name and title on one side, and the coat of arms of Portugal on the other. It's made of Billon, a type of alloy that is composed of a mixture of metals, and weighs 2.7 grams. Despite its age, this coin remains a valuable piece of numismatic history and a testament to the economic and political developments of Portugal during the late Middle Ages.
