Hello
I have 1805 EM Denga which was sold on 2013 St James auction in England
https://www.m-dv.ru/catalog/p,142664/image.html
Two collectors said that it is counterfeit coin cause dies do not mach (letter and number punches are different that they used) and edge is completely different from the others. I found that there are two types counterfeit coins of 1805 EM Denga which were made by copying from original pattern
I couldn't find this type of coin in any catalogues and selling history in m-dv.ru so I decided to sent this coin for grading with all the
