Princesas de Portugal, Rainhas da Europa (Princesses of Portugal, Queens of Europe) - printed in Portuguese

Here we tell you the exciting stories of four Portuguese princesses from different eras who married kings from other European countries and who were either happy, or unhappy or so-so. And, hey, Leonor de Portugal, Isabel de Portugal, Catarina de Bragança and Maria Bárbara de Bragança were so important, powerful (and nice!) In the time that each of them lived that the Official Printing Office (INCM) and the Museu Casa da Moeda decided to devote them a special issue of commemorative coins.
