My grandparents lived in Chicago in the 1950's and my grandfather was a salesman for a French company.
In 1956 his company sent him and grandmother to Paris for a two-month tour of western Europe. They flew from the US to Paris and back to the US.
I was eight years old then and my grandmother gave me the French coins she brought back.
I was fascinated by the "foreign" coins.
One of them:
France 100 francs 1956
Copper-nickel, 24 mm, 6.0 gm
The Mysterious Egyptian Magic Coin
Coins in Movies and on Television
The 1949 San Francisco Mexico Peso Restrikes
