[QUOTE="Julius Germanicus, post: 2743064, member: 80783"]Another update: The seller´s expert has re-examined the coin and stated that he has investigated it by microscope using a Leica MZ95 as well as a strongly magnifying Keyence digital microscope, several LFK measurements, and additionally an X-ray fluorescence analysis to interpret the LFK values. Regarding the conspicuousness of the SC he explained that similar conspicuities could also be found in non-suspicious pieces from this reign (for example, BMC 43, 7). The lack of sharpness mentioned in the forgery report could be explained by the treatment of corrosion: A light microscopic examination of the piece had revealed that the coin was clearly corroded. Corrosion would clearly be visible at the edges. The corrosion had apparently been smoothed in two steps (first with a somewhat coarser tool, then presumably with soft wood, as was customary in the past.) Casting features such as bubbles and dendrites were not present. The LFK value would not indicate a cast either, all measurements would not show any abnormalities that occur during casting. They would understand that I was unsettled by the advice of David Sear and the discussion in the German forum (where almost everybody thought the coin was a cast with similar arguments as David Sear has put forward) and offered to refund the purchase price and offer the coin again in one of their next auctions. What do you think???[/QUOTE]
