Buried way down in the bottom of one box was a small baggie, filled with Canadian currency and some other unusual coins. I'll probably never know the story of how they got there, since to my knowledge no one in the family had ever been to Canada, but I was certainly intrigued by some of the other items that were with them. These coins were not legal tender, but were either souvenir or promotional coins that provide a small glimpse into the history of American advertising.
