So I have not found this one in the Books or on VAM World.. 1884O w/ Light die crack from under the B in "Plurbus" running to the bonnet then onto the "U" on the Obverse.. But the Big Mark is the Die clash I guess (?) on the Reverse ,, right of the right Eagle Wing coming off the wreath ... Oh and I have been playing around all day with my invention.. Plying with optics.. Not a bad Close up on the 1889O VAM6 for a broken camera connected to a few lens .. LOL.. I will be looking for a cheap web cam and a Microscope tomorrow for my next idea..
The reverse marks are a die clash from the lower part of Liberty's cap. Both the clash mark and the die crack aren't key identifiers, they are both very common, so they probably wouldn't even be mentioned, possibly the die crack but only as a secondary identifier if it's really strong. To identify it I would start with the date and mint mark, whether it's the far-date or normal, any doubling on the 18, and is it the oval O or round O, and any doubling on the mm.
