One interesting fact about the Standard circulation coin 1 Real of 3½ Libras - João I (Porto) ND (1398-1408) from Portugal is that it was made of Billon, which is an alloy of silver and copper. Specifically, this coin contains .125 silver, which is a relatively low percentage of silver compared to other coins of its time. Despite this, the coin still weighs 2.6 grams, making it a substantial piece of currency for its time.
