Coins vs. Bills

Should we follow Canada's lead and kill the bill? I prefer $1 coins and would be happy to see the $1 paper bill move on. Canada has finally made the leap, although for years they have had the loonie and tooney as sucessful $1 and $2 coins. Here in the US we were never able to make the sucessful jump to a $2 paper bill let alone a working coin. Maybe we can twice follow Canada's lead and get rid of the penny too. At least now I know my change from the store will eventually no longer have Canadian pennies. ;-)
