One of the coolest things about collecting pennies is that not too many people do it. Granted, it’s probably more than I would guess. But still, it can’t be too bad. Otherwise, nobody would ever get good pennies back as change from the store. Or maybe, the fact that we do on occasion get a nice wheat penny, is simply because only a very small percentage of retail clerks collect pennies. Which is a good thing. Because every time I get behind the counter, I rifle through the pennies in the tray the first chance I get. And because of that, I have a pretty respectable penny collection. And because of that, I know how to clean pennies. And yes, I know, you shouldn’t go about cleaning pennies all Willy nilly. Some of them are valuable and you don’t want to screw that up. Most of them, however, ain’t worth a damn. They’re just cool. And dirty. And so it’s easy to understand how one such as myself (and you, of course) would want to know how to clean a penny. Well my friend, if you want to know how to clean copper pennies, wheat pennies, steel pennies, or even zinc pennies, check out this article.
