The lighting may be throwing me off on this one. It appears that the branches of the tree are faint to almost missing. The same on the WE TRUST. In the field under DOLLAR you can see heavy die flow appearing. The QUARTER looks very weak. That is what I've noticed about this coin. So it may be a combination of struck through grease/heavy die wear or even abrasion from cleanings. So it may be a combination of things on this coin.
