RitaENP New Member United States 4 Posts	Posted 05/26/2025 8:04 pm Hello I found an odd 2004 D penny. It looks beat up, but I am not 100% sure that is the issue. I think it was struck on the wrong planchet. I found it in my father's collection in a cardboard coin holder. This is one of the last coins he must have put up. He died shortly after this. The penny weighs 2.1 grams, is 1.1 mm thick, and 17.1 mm wide. The edges are very smooth. I found that a danish coin meets the specs, but was not produced in the US. I would appreciate any feedback on your thoughts and whether it might be worth any thing. Thank you Rita Report this Post to the Staff

HondoB Bedrock of the Community United States 25008 Posts	Posted 05/26/2025 8:21 pm to the CCF, RitaENP! It's visibly a copper-plated planchet, so we can rule out incorrect planchet. I don't think it was acid, as more of the copper plating would have been stripped off. But being underweight as well as smaller in diameter, I think that the edge was ground off some sort of way - it does appear to be out of round. If the edges are grey instead of copper-colored, my suspicion would be confirmed. Inordinately fascinated by bits of metal with strange markings and figures Report this Post to the Staff

RitaENP New Member United States 4 Posts	Posted 05/27/2025 12:56 am The edges are smooth and cooper. I do not see any grey other than what is on the back of the coin. It dose not feel like it has been ground off. It is out round. It is not bent. I agree, acid was not used because I can see all the features except where the pitting is. My dad had a couple of coins like this. I am stumped. Thank you for your comments Report this Post to the Staff
JimmyD Bedrock of the Community Canada 21589 Posts	Posted 05/27/2025 06:26 am Not really anything to be stumped about, it is a damaged coin that has zinc rot. How it happened does not really matter, all that matters is there is no way that it looked like that when it was struck. Report this Post to the Staff
ijn1944 Bedrock of the Community United States 19127 Posts	Posted 05/27/2025 07:06 am Yes, post-strike damage and zinc rot. Looks to have been deliberately 'resized'. As noted, the coin didn't leave the striking chamber in that condition. Report this Post to the Staff
oddguy Pillar of the Community United States 4135 Posts	Posted 05/27/2025 08:05 am Back in time say, pre 1970 (note I was a private in the army making $187 per mo.) a dime was a lot of money and some would grind a penny into a dime size for vending machines. Looks like the coin here. Report this Post to the Staff
