It's also penny in the UK as well, pence is for more than one penny
Now way backin time, when the half-penny was eliminated in the UK, that was a smart move!
If pennies or cents were eliminated, individual products would always go up by at least 5p or 5¢ at a time. For a cart (or trolley) of groceries, that would sure add up fast!
People who wanted to keep them can keep them, and other people who want to donate them can do as well. But it's probably here to stay for a while yet!
