I got this in change today. It is clad 1992. I'll try to take better pictures when I get home. It appears to be the same size and thickness as a regular nickel.
Definitely dirty. Gonna give it an acetone bath. Lots of copper showing on it. Including the outer rim.
Yeah, but WHY would copper be showing? Its not missing a clad layer like a dime-half could, right? The metal in these are alloys, so a missing clad layer is an impossibility. So the only explanation can be PMD.
You left out struck on a different planchet which is exactly what this appears to be. I just don't know what kind.
Looks like it spent quite a bit of time under a coke machine in a dried puddle of the chemicals the machine dispenses.
Here are a couple extra pictures. I have it soaking now. Alot of the black is coming off. It is clean enough now that I can see the layer of nickel and the copper clearly. I believe it is unmixed alloy instead of clad. There is definitely separation of the two metals.
As more details reveal themselves, would you believe this coin is also clashed?I I was so excited that I didn't even notice it. You can see it on the reverse in the pictures above.
If it turns out as you hope it may just have been a fire damaged coin from someone's collection that sadly had to re-enter circulation. Good luck on this. keep us posted.
