It really seems to me that Mr.
Prokopov is wrong that the marks are an evidence for the use of modern machines, and probably the
numiswiki article and the
fake reports should be edited accordingly.
I found an article in
money trend 7-8/2010 about experiments with die cutting. The coin to copy was a
medieval gold coin comparable in
weight and size to a late roman/early
byzantine tremissis. The circles were
engraved with a lathe, the dots with a punch and the lines with chisel and hammer. On magnified pictures of the copy you can see marks similar to the marks in question which are caused by
tools which were available and probably in use by an ancient die cutter, too.
I
hope it's all right to show the details of the engarged pictures for educatioal use here.

Stefan
