This one I can't figure out. only stuck on one side. Has a bevel on the rim that is too accurate for a person to grind. when lying flat reverse side up on the table it is slightly taller than a regular nickel. Its weight however is only 2.9 grams. I don't think anyone ground on it because they could never be that accurate on the rim. and why would they do it this way anyway? So thought I would let you guys look and see what you think. crazy coin.

It has been altered in some way, doesn't matter how, that is why it is light.
You can't have a coin that is only struck on one side.
That is like trying to clap with one hand.

appears to be stuck one side. didn't mean it was. it defies all logic and would challenge anyone to replicate it.

uni face errors are only stuck on one side. I'm not saying this is one. but coins can be stuck on only one side.

I'd be interested to see an example of this. Can you please post a link? Thx.

The 'ground out' obverse could easily have been done using a precision machine optimized for metal working/fabrication.

CNC machine for one.
I too say it was altered.
I think we need a much better image of the coins edge on perspective. and tell which side is which please.

This is a machine shop modified coin.

Any competent mill operator would be able to remove the surface and bevel the rim of a coin. The process would be very similar to milling the profile of custom wheel for a car.

Very easy to grind down the surface without affecting the rims - see a Magician's coin.

Full uniface errors are a thing:

https://www.error-ref.com/full-uniface-strike/

However, with almost 50% of the weight of the coin missing a more realistic explanation would be post mint removal of the material to form a Magicians coin or some similar device using a lathe.
