Here are two auction sales. (Not eBay.)
The upper coin sold for about $300+fees. The lower coin sold for about $600+fees. I do not have access to the coins, I merely stumbled across the photos online.
My first impression was that I was looking at two different coins. At least one of the coins is a modern cast forgery.
Several people suggested that it was more likely that both pictures show the same coin, before and after a 'repair'.
I am curious what my readers think. In the comments, tell me if you think these are one or two coins, genuine or fake, repaired or not. I can tell you that the reported weights are within 0.3%.
