I had been in Brazil, Rio de Janeiro and parts of Sao Paulo and Minas Gerais States. I saw a couple nice collections of world as well as more specifically Brazilian coin collections at museums in my travels. I may post more about these later. There were a few ancients in the mix though these were just provided as examples of earlier coinage.
For now I need to relax having just come back.
