While sorting my Victoria Empress silver rupees for different years, I found this 1877 Rupee coin, which has a Ghost image of Victoria's effigy on the Reverse.
Nice clash I am just wondering why the obverse does not show any clash marks. The obverse could have been switched out?
That would be my thought. Perhaps the clash was more noticeable on the obverse due to the big open fields?
Maybe a better candidate for a heavy polishing. At this time dies were expensive to make so switching one out wouldn't usually happen unless it broke and even then the US still used them.
I'd think maybe you'd see some die polish lines then. But what do I know? EDIT: seems there were several obverse/reverse pairings on the 1877 https://en.numista.com/catalogue/pieces3719.html
But the obv COULD have been switched out for another obv die while the first was being polished/reground to remove the clashmarks (that would give you a clashed rev with an unclashed obv), and then paired with another reverse. It is also possible, depending on the relative hardness of the dies, for clashmarks to only be transferred to one die when a clash occurs.
