Let me tell you about an exhibit in the university museum that you might want to see. There are showing a collection of coins and paper money used in North America in the last two hundred years. the exhibit also includes historic facts about the various froms of currency. One interesting item I saw there was a currency note from Canada---a piece of money worth only 25 cents. I've never seen a bill worth so little. The Canadian government issued the notes in 1876 as a temporary solution to a shortage of coins. The plan was to use them for only a few years until enough coins could be made. The people found the bills so useful that the Canadian government printed more in 1900 and 1923, most people simply like the bills because they were easy to hold in a purse or to sent through the mail/. They are only about half the size as the current bills. But what's unusual is the way the soldiers used them. They would stick them down in their boots to prevent the boots from rubbing against their skin. You can't image how irritated your shrinks may get your boots' rubber against them all day. So the durable paper really helped. As shrink plasters in 1935 and ironically those that were not destroyed are now valuable collect this item like the one display at the museum
