I have come across two coins that I need to verify real or fake? I know nothing of Russian coins and really need help. I am posting photos of both.
Don't know those, so don't know if fake or not. Check to see weight and if they are magnetic and check the edge for a casting seam.
Nothing about the 1780 screams fake to me but the 1724 looks off. Check the weights and post pictures of the edges if possible. Are these coming from a reputable dealer, eBay or some other venue.
Both are wrong and there is no need for magnets etc. Details are completely wrong and could not have been manufactured back in 1700s with the technology back then I would want to be paid to get rid of them, not paying to own them.
