*** Edited by Staff to Add Year / Mintmark / Denomination to Title. Titles are Important! ***I remember learning when I was a kid that if you drop one of these on a, let's say, wooden table top a copper one will have a ringing sound and the zinc will have more of a muffled thud. I've also been pretty thankful that the 1982 small and large dates are very obvious. Unlike the 1970-S that messes with my brain.

The zinc pennies should weigh 2.5 grams and the copper should weigh 3.11 grams. There is not much difference and scales can easily measure a lightweight coin such as this incorrectly. Other variables like dirt from circulation could throw the weight off. I would say your best bet is to get a small electronic scale to weigh the coins.

You can get a gram scale off of ebay for 5-6$. Stop dropping coins and putting marks into your wooden tables. Copper 3.1 grams, zinc 2.5 grams |

You can also make a balance with a Popsicle stick and a round pencil. I actually made one with some Lego pieces. Works fairly well.  |

I do a "coin toss" flip. Copper rings, zinc goes thud. It's a lot easier to distinguish (for me) than throwing the coins at a table, and your fingernail is too soft to mark the coin.
Obviously don't do this with MS coins, but if you're stacking circulated coppers, what's the harm?

Ring test here all the way. Fastest and the most frugal of all (not that toothpicks, emery boards, and pencils are particularly expensive, but you know, technically)....

I like a glass table, when dropped on it the difference is like a church bell versus dropping a brick on grass. It's so easy to hear the difference! I also sometimes use the coin flip method, copper makes a distinct high-pitched PING while it's in the air, zinc doesn't.
With experience, you'll eventually be able to spot them by eye. I have a 99% accuracy rate just quickly looking at the strike and patina (color). My first step when searching is to create one pile and separate out the copper. Makes searching WAY easier when you know what to look for based on if it's a copper or zinc coin. GOOD LUCK!

@Crazyb0  And I concur with BadThad. I am not advanced enough to ID them by sight but I can definitely hear the difference between Cu and Zn whether it be dropping or flipping (and yes, that ringing as it spins in the air is quite distinct). Edited by CelticKnot
