Still, most prices, such as $4.99 or $13.56, require cash purchasers to hand over pennies or get them as change. Will ending penny production force all prices to be rounded to the nearest 5 or 10?
Probably not for a long time, says Robert Whaples. He is an economist at Wake Forest University in North Carolina. In cashless transactions, people will still be able to pay exact amounts. As for cash payments, Whaples says, nothing will change until the number of pennies in circulation drops significantly.
“If people keep them in their jars at home and don’t bring them back to stores, eventually the stores will run out and start rounding prices to the nearest nickel,” he explains. “For example, a cash register total of $1.99 will be rounded up to $2, and a total of $2.01 will be rounded [down] to $2.”
Some people worry that this might cost shoppers more in the long run. Whaples, who has studied some 200,000 sales from a chain of convenience stores, disagrees. Based on his research, he says, the changes generally even out. “No one will see much of a difference. I found that rounding to the nearest nickel goes slightly in favor of buyers—but the amount is very small.”
Other nations, including Australia and Mexico, have gotten rid of their low denomination coins in recent decades without negative effects on consumers, some experts say.
Canada, for one, stopped minting its pennies in 2012. The change was relatively uneventful for shoppers, says Sarah Halpern-Meekin. She is a sociologist at the University of Wisconsin-Madison who studies how government policies affect low-income families. “There didn’t seem to be major problems or challenges.”
