Survey: Coins or Bills?

Jenna's post about the new American one dollar coin generated some controversy, but I noted one commenter about "the public's willingness to use these coins." In Canada and the UK, there was no issue of choice; the mint just did it and we got used to it. The vending companies bit the bullet and suddenly we weren't feeding endless quarters into machines like Americans do for a chocolate bar or a parking meter, just one coin did the trick, and their sales went up because of the convenience. (there has been inflation, you know) The street people loved it- when the Canadian toonie came out one said "hey, the Prime Minister just gave me a raise!" So here is a two part quiz, questions for Americans and two questions for readers from countries where people have faced change and dealt with it.
