Looks like a polishing mark that tried to cover a clash. You can see the clash mark on the brow, and the top of the hair line. It was partly removed, but not all. Near the 'L' area on LIBERTY the rough look on that area looks like Struck Through Grease with a little grit in it. The grit may have caused the lines when the grease was pushed on the field to just under the 'L'? But not much of a premium for this unless you collect clashes. First time I seen this before though.
