Pennies, the one-cent coins in everyone's wallet that worth nothing and also extremely useless.
"It cost the United States Mint 1.7 cents to make a penny which means that every year seventy million dollars over federal tax money goes to subsidizing the existence of the penny." --John Green
Canada, New Zealand, Australia, Finland, and the Netherlands had gotten rid of their one-cent coins already. There is no point to keep using pennies, the coin that is extremely useless, worthless, and a waste of our tax money. It's time for us, as a nation, to get rid of pennies!
