I don't see anything about a WIDE AM for the 1993-D Lincoln cent, but was hoping it was just like the very scarce 1992-D Close AM. Pictures are enclosed SORRY TITLE SAYS CLOSE AM- SHOULD READ WIDE AM
To my eyes there appears to be plenty of space between the AM not to be a close AM variety. (after enlarging) But wait for the others to chime in. I have been wrong before.
I wouldn't label it a discovery coin. That really does not look like a Die Crack. Add some better pictures with different lighting.
Sorry this is a close AM, the normal reverse for the year. It has had some die polishing which has cause the AM to be further apart than typically seen, but it is still the close AM hub.
