Well, if you do not mind damaging the coin, get a knife, scrape a deep line on the coin, then put your finger on the line for about 10 seconds, if the line stays copper colored its copper, if it turns black, its zinc.


Very time consuming. A simple Butane or arc welder torch will show all Copper much easier and faster.

Do you have a nice comment for the people that are blind?

Blind people usually have excellent hearing so this technique should work great for them, the problem they will have is determining what is an '82.

How about a nice statement for the ones that don't have fingers?

Nope, gonna have to come up with a completely different technique for them, though they might hear the ring if they could figure out a way to filp the coin.

Turn up the Belltones? Nice expression, thanks. Some of us old people just can't hear the difference in tones as we could when we were young. Nothing to do with being DEAF. Just getting old.

Simmer down, I was just playing. But, for the record, it isn't so much a differance in tones as a copper coin will ring like a small tuning fork and a Zincoln will make no sound at all. Give it a try if you haven't. And I was just teasing about the beltones, if you can't tell a difference, then get a scale, make a teeter totter out of popcicle sticks, do whatever you gotta do man.

You must realize there are numerous elderly individuals that are somewhat handicapped due to illnesses and old age. Myself included and we really don't appreciate being made fun of. Several friends of mine have MS and their hands shake continuosly. Why not make fun of them also. My hands shake, I've had numerous operations in the last several years due to cancer. My hearing is fading.
Simmer down? HOW?
