Looks like he collected world coins too. I am just finishing going through 10 lbs of world coins and found about 60 coins from Brazil. Seems this batch of coins had mostly South America travelers change.
My dad worked different areas. He stayed in Brazil for two years. I have some from Spain and etc. I am thinking during the 2016 flood lost some. I did pass some on to my brother for his son. My grandfather was born in Spain and grandmother in Italy. I am wondering why he did not have more unless mom kept them a certain place. Will see what I run into. I wished I would have taken photos of the ones I gave my brother.
