I don’t know much, well, anything about die breaks, but I came across a potential here and wonder if anyone else has seen it. It appears as if the vertical portion of “L” in Liberty is snapped in the middle with the bottom section tilting right. I will try and get a good magnification photo.
I think that is damage caused from being hit with another coin. The "I" also has incurred some damage itself.
There are CUDS - http://cuds-on-coins.com/ And there are Die Cracks and Chips - http://www.lincolncentsonline.com/cuds.html
Here’s a better candidate. 1972 D Kennedy half reverse die crack? Is there a registry or something for these things?
