Interesting fact

One interesting fact about this coin is that it has a unique countermark, which is a mark or symbol that was added to the coin after it was minted. In this case, the countermark is the number "100" stamped over the original denomination of "LXXX Réis" (80 réis). This countermark was added to indicate that the coin had been revalued to 100 réis, likely due to changes in the value of the silver content or to combat inflation. The use of countermarks was a common practice in the past to modify the value of coins without having to mint new ones, and it adds an interesting element to the history and collectibility of this coin.
