I have a 1969s penny that appears to be nickel instead of copper. I've seen coins that have been coated with different things and it is very noticeable. The lettering and all details of this coin are very sharp and distinct. I would think that if it was coated with something that the S would be filled with the coating, but it's not. It is very clear. I don't have a scale to weigh it or a camera for pics (sorry). Any info would be helpful. Thanks. Forgot to mention that the O.D. and thickness seem to be the same as any other penny, haven't put calipers or mics on it though. Edited by crazycharlie75

Could it be coated with mercury?

Hi,
I know you are at a disadvantage without a camera but when color is an issue a picture is practically a must. Is there a chance that you have a flatbed scanner and can scan the coin and post it?
Thanks,
Bill

I think a good scale would be the most useful too here.  |

Looks like mercury to me. I did enough of that sort of thing when I was a kid in high school (fifty years ago) before we knew of the associated risks of messing with the stuff. We used to sneak it out of chemistry class in a 35mm film canister and carry it around in our jeans pocket! We used to call it quicksilver.

another way to test these without a scale is to drop the coin on a table with one you know is normal. If they make the same sound, they are probably both made of the same metal.

I brightened the pictures a little bit and the pictures are helpful but not conclusive.
This coin seems to have more detail visible than most plated coins that I've seen.
I would continue checking this one out as to weight and I would try to 'perhaps' get a friend to take a digital picture so that you could post that.
Although it is likely microplated, I wouldn't give up on this one just yet.
Thanks,
Bill

Good test to see if its mercury is to swallow it. If you die, it's probably mercury.

If you don't die, then you will probably have all the copper you need till it passes? Mercury looks nice and silver colored when it is applied, but later turns dark and poisonous. Scanning a coin. If you place a darker piece of material over the coin it takes out some of the contasting color because of the white backdrop of the scanner. On my scanner it will crop the area around the back material and remove the white unwanted area of the scan. Setting you scanner for a higher DPI setting will also improve your images. Here are a few images. See if you can figure out what is wrong with each image. Answer below images. High lite that area.    These coins weren't minted those years!Edited by coop

A decent quality electroplating will cover the coin without losing any of the fine details. A quick flash plating can give you a good color and still only be a few millionths of an inch thick

The picture is on a black background.

SeattleMD, I thought elemental mercury ( quicksilver) was not absorbed through the intestinal tract, contrary to methyl-mercury which is passed through the food chain multiplier. Perhaps I remember wrongly.

I didn't even know there were different types of mercury, so ya, you win :)
