I'm not sure what I'm seeing on the reverse of this coin. Maybe I should say that I'm not sure what to call it. It appears to be the obverse device (Lincoln's bust), but I don't see any detail at all, just a faint/ghost figure. There doesn't seem to be any die abrasion marks indicating that a clash was removed, but that might not be indicative of anything other than a skilled mint worker. Notice the weak strike at the top left corner of the Memorial building. Does that provide a clue as to what is going on?
I know something is there, I just don't know what it is. What do you think?
