Hi everyone,
Another question for your great community !
I find this coin and I wonder what happen (fire?) or if it's a real error..
First the pics


On the face side (sorry for my poor english) there is like a bubble under the chin.
On the reverse, coin is very dark,some weird relief (bump and hole) and there is like a piece of metal paste on it.. dont know if you van see it.
Have you ever see that ?
Thanks a lot for sharing your time and experience !
