Got this recently as it was cheap. Low grade isn't a problem for me however authenticity is a different matter. Weight is at 2.72g. What are your thoughts on it?
I am not knowledgeable about these, but looking at other examples of the 1942 15 Kopek, the date does look tooled and re-engraved, to me. Top and right hand side of the '2' look incorrect.
It looks weird, but I don't know anything about these. Is the 42 a key date, or something that would make it worth altering the date? What sort of price range are we talking for these, versus a common date example?
1942 15 kopek is a key date of this type. A common 15 kopek in this condition may be worth about a dollar versus 100 - 200 dollars, if not 300+ dollars in XF condition. There is a big difference in pricing so it comes to no surprise if there are counterfeits or altered dates of this type.
