This coin was cut. Note the affected areas are not plated. It was a normal coin when it was struck.

If the weight is 2.5 grams I would like to see it on a scale with a pic of that.

Agree, attempted deception.

Agreed - cut coin.

Note the affected areas are not plated. So if that is a zinc core cent then after it was cut did someone cover the cut area with some copper metallic paint to cover up the zinc? Pretty sneaky I'd say... |

I'm guessing the only way to make sure it's a copper 83 instead of copper coated zinc would be to take it to a Jeweler or Pawn Shop that has an XRF gun -

Puzzling that it weighs 2.5 grams with the apparent damage. Someone needs to give Mike Diamond a shout.

I guess I'm the contrarian here, but I'm not convinced it's entirely PMD with the way the rim on the right side fades into the clip. The one on the left doesn't seem as promising. But the weight is bizarre... What does the clip on the right side look like from the edge? |

Did you punch in on the tare button. That will set you scale back to zero. Then check the weight.

It is still way too light to be bronze.
I agree with the OP's proposition that it would be a 20% clip if the clips are clips because (3.1-2.5)x100/3.1=19%, and therein lies the problem...
Divide the coin into fifths (20%). Now mentally lay those clipped pieces in each slice of that pie. Not close to equaling that slice, is it?

 So, in a variation of the ancient, precomputer age method of integration called "cut-and-weigh" paper, I weighed the whole of my model cent and the model cent after clips. I am working from a phone screen. If I were using a computer, I would print the image of the cent and work from that. As is, I think I got close to the correct proportions. Anyway, the percentage of clipped area inferred from the weight is only about 5.9%. 5.9% of a 2.5 gram zincoln only knocks off 0.15 grams, so 2.4 or 2.3 grams on OP's balance. . 5.9% of a 3.1 gram bronze planchet only knocks off 0.18 grams. On the OP's balance, that would show as 2.9 grams. The stated measured weight of 2.5 grams is closer to which one? Edit for spelling and for some sloppiness with significant figures.

I realize that the coin will have a more variable weight distribution across it (higher mass per unit area at rims and in the middle with higher relief devices) than my model, but this picture is closer to representing a 20% clip. I crept in to the correct weight by gradually snipping off pieces. I have a feeling that we may overestimate clip area on a coin the same way most of us would grossly overestimate blood loss by looking at what has splattered on the floor, or soaked into our pants leg.... Don't ask.  |

So painting the zinc core surface, that was exposed when the cuts were made with a heavy metallic copper paint, actually could have brought the coin back into zinc cent tolerances?  And I'm sticking to the paint theory - otherwise how do you explain the copper colored cuts when @coop stated about seeing the copper plating? EDIT - where's @Silviosi when we need him. Wish we had a "TAGGING" option. Edited by Rothery
