Hey all, I wanted to post an oddity and hope someone may have an idea of what this is... So, I found a 1952 wheat penny that is very thin and weighs only 1.6grams, it is also very thin. I'd say thinner than a dime Unfortunately something is wrong with it. You can see in the pics, it looks to have been eaten away at?? I imagine it would weigh 1.7 or 1.8 in original state. I assume it is a wrong planchet error/ foreign? Can anyone provide some insight. ~Regards b3rt
Hi guys. thank you for your replies. It is possible this was a MD find, that had gotten into my unidentified/error coin pile. Would a coin that has been found metal detecting or have been acid soaked appear in this state thin and "corroded" & still retain this amount of detail? I would just automatically assume that losing 1/2 it's weight there would be no details evident?? Totally my own assumption. Haven't seen anything like this before. Thank you ~regards b3rt
Yes, that is how it goes, the devices are reduced as well as the field which leaves the detail somewhat intact.
Short answer: yes. As I understand it, when you strike a coin, the metal that flows into the devices -- the profile, the lettering, and so on -- undergoes work hardening, where its bonding structure changes, making it harder and more resistant to chemical attack. That's why you can restore dates on dateless nickels. I think this effect is fairly strong for copper and copper-nickel alloys, but very weak for silver, and practically non-existent for gold. That's why it's difficult or impossible to restore dates on silver. (I've never come across dateless gold, and probably never will.)
If this coin were in good condition and weighed 1.6 you would have a nice find. Thin planchet probably. This coin is damaged. Looks like acid ate the metal away. No value above face even as a wheat.
