In Australia they don't use pennies. They round up or down, unless it is a plastic transaction. They don't seem to have any problems with it at all. There are a lot more 50 cent pieces in circulation, and they have a $1 and a $2 coin as well, so no $1 bills anymore either.

I think coins are much dirtier than bills. People are dropping coins all the time, and most panhandlers and beggars are paid in coins. Coins have a lot of nooks and crannies for stuff to lodge into.

I think we should go back to shells and beads.
