If people yelp about using the term penny rather than cent you can remind them that when they are received directly from the mint, the mint (the guys and gals that make them) they have PENNY on the roll from the mint. Not cent.
If I open a box labeled "DOGS" and it's filled with cats, does that make them dogs?
The cent says "CENT" right there are on the reverse. I've looked at a lot of them and not one of them says "Penny".
