Comment: I use dollar coins (Score 0) 815
The bank tellers like me, because I take them out of their drawers, and they don't have to count them at the end of the day.
The thing is that dollar bills are borrowed from Wall Street, while dollar coins are government-issued money. I don't think JP Morgan Chase and Bank of America should be trusted to make the economy's money supply, so I try to always carry a few government-issued dollars with me.
