Thank you very much for your responses - faster than lightning
The seam is not actually there - it only looks like it on the photograph (I apologize for the
poor quality).
By the way: The small damage at 3 o'clock on the
obverse looks like the traces a forceps would leave. It is not a
crack, although it looks like that on the photo. Maybe it happened, when the coin was held in place to drill the hole. The hole was not punched for sure.
rover, I have to say, I am relieved to hear that you think it's genuine. Since I am a student, it would have been a big financial (and psychological) loss
(three days
work in a warehouse at least).
Thank you again!
