1983 penny with odd weight
Hello everyone, I have a 1983 penny with a weight that does not match any of the other weights, the zinc pennies are between 2.48-2.55 and the copper are 3.06 - 3.12, the weight on this penny is 2.73, I’m debating whether I should send it in for verification or will I be wasting my time. 46B78CF0-12C0-4EED-87B7-CFF73895852D.jpg B5F39F2C-5DA7-49B6-9973-363651FE3C0F.jpgTags: None

A copper/bronze cent is supposed to be between 2.980 and 3.240 grams.
Zinc cents should weigh between 2.4 and 2.6 grams.
Planchet production is not an exact science. Its like rolling out dough in a sense. Some places will be slightly thicker than others. That may affect the overall weight.
One thing to consider is the calibration of the scale. You would have to know if yours is truly accurate. The more than likely zinc cent is just 0.13 of a gram off, which is not that much.
One thing I recommend doing is carefully use a low powered magnet to see if the coin is attracted to it. You may want to place a piece of cloth or plastic between the magnet and the coin so it won't damage it.
All of the devices look like they are on the coin so that should push the coin in the direction of being the right sized planchet. I suggest laying down on a table and placing another cent next to it to see if they are close to the same height.
A "ring test" could be done. Get a known circulated copper cent and drop it from about 6 inches on a marble counter top, finished concrete floor, tile floor or other hard surface. You should hear a pronounced ring when it hits the surface.
Zinc cents tend to be a duller noise. It is at your own risk to attempt the "ring test".

I personally don't see enough to consider this a wrong planchet or on a foreign planchet.
