Comment
The picture is from the unique coin known and belongs to INCM Museum (Nr.22102)Interesting fact
One interesting fact about this coin is that it has a unique countermark, "1U" over 500 Reais - Sebastião I, which indicates that it was issued during a time of currency reform in Portugal. The countermark was added to the coin to increase its value and make it equivalent to 1000 réis, the new standard unit of currency introduced by King João IV in 1645. This coin is a rare example of a coin that has been modified in this way, making it a valuable and interesting piece for collectors.
