Rick, I saw the line you pointed out and it does not look like seam lines that I have seen on other
cast coins. If it was a pressed
fake as you pointed out, why would it have a seam line?
As for the marks on the surface that Arya believes to be file marks, they don't look like file marks to me because they are not evenly spaced apart like the teeth on a file would make. They look like normal scape marks that would occur if some one dropped the coin or handled it too roughly.
Is the coin a
counterfeit or not, I really don't know and would not want to make a judgment call without seeing the coin in hand and doing a lot of research. I just can't tell from the photographs alone.
