Support the retirement of the U.S. penny.
In 2011, the production cost of a penny was 2.4 cents per coin. The U.S. spent almost $120 million to produce less than $50 million of circulating currency.
The Department of Defense abolished the use of pennies at overseas military bases more than 30 years ago. If the military deemed the coins "too heavy and not cost-effective to ship," the same logic could be used in the States.
The Mint stopped producing the half cent in 1857, when it was worth what a dime is worth today, and there was no public outrage or damaging economic effects.
For those concerned that Abraham Lincoln will be forgotten, he and his memorial are firmly ensconced on the $5 bill.
It's time to retire the penny.
