There is some writing behind the coin, so not all is readable.
The previous owner bought it for about 20US$. A couple of weeks later he was contacted by the seller, because he wanted to by back the key.
So the previous owner was convinced there was something special about it and was convinced it had to be real.
The current owner is also convinced it is real....
A real one would be 800-1000US$. Here the value of 20$ is more realistic.
I am convinced it is a replica, and I think the label on the back says the same.



Kenny, what do you think?
Thanks for any help.
