Nice, looks like 1DO-001 (Cherrypicker's variety 1C-021.93). Hard to judge the whole grade of the coin based on a single picture, but I would think you could get between $10-20 for it on ebay.
To the left of the 1 and 9 in the date, and also a doubled eyelid. http://coppercoins.com/lincoln/diestate.php?date=1955&die_id=1955d1do001&die_state=mds
Jon, It does appear circulated and with a fingerprint, so the 'BU' would not be part of the description. It is very hard to tell from a LED microscope photo, but it appears to be AU50 -RB to me with only one photo.
