Here is another one I found in my stash. It has several die cracks on the forehead of Lincoln and a large chip on the left wheat stalk.
The cracked skull is hard to tell if it is a lamination crack or the begining of a large IDB. When I looked here, I noticed they have quite a few (RIDB) retained interior die breaks removed from the listings for 55 D. neat coin Inspector. http://cuds-on-coins.com/lincoln-cent-retained-interior-die-break-1909-1958/
