[QUOTE="Ed Snible, post: 4846053, member: 82322"]In Wayne Sayles' book _Classical Deception_, page 55, he talks about a disagreement between authenticators was resolved in 1963 when the fakes were shown to be 2% smaller than other coins of the same die. In other words, highly deceptive in the 1950s Sayles' book doesn't say how they were compared. I would guess photographs printed on transparencies but even that is hard -- the photographs must be taken precisely. Using a comparison microscope? Usually fake detection doesn't reach this point because the forgers take shortcuts and do things like incorrectly touching up dies created from off-center coins.[/QUOTE]
