It is def copper, def very old, and unfortunately like many old coppers I have found (half penny for example) it has been in the ground long enough that it is now thin and slick.
No details left except for one thing I noticed- it has a line around the perimeter on one side. Just in from the edge, maybe 2mm, there is a line going around. The type of thing where I can see it if I hold it just right under the light but the camera won’t pick up on it.
Don, there is nothing to see. As mentioned the camera won’t pick up the detail line I am talking about.
It looks just like a worn slick thin old copper from 200+ years ago.
The shape is even all the way around, and perfectly flat. It is not a railroad coin, there is also no railroad anywhere nearby- and not one of the novelty crank stretch coins. Much shorter than that.
I guess it will remain a mystery- left in the ground too long.
Could the line around the perimeter be the raised edge of a penny after being flattened?
Here are a few RR coins I have found.
One tell tale sign of a flattened coins is that sometimes one or both of the pointed ends of the oval will be slightly thinner than the middle (between the two points).
definitely a coin that a UFO landed on. we could compare this to the Roswell incident but all those coins were confiscated. check it for radiation and don't keep it in your pocket
