This 2009 professional life lincoln has two die cracks. One is on the obverse and the other is on the reverse. The other mark might be a die chip. Just thought I would post some images of them
Looks like die crack and die chip on the reverse. Any sign of doubled dies on them? The LP2 mint boxes were full of them. I'm opening a couple boxes of the first batch that I get. Then see if it is worth re-ordering.
I'm guessing die wear. Die wear appears on the outside of devices that face the rim and your coin fits the bill.
