Eyelid, hair details are strong in some places and almost non existent in others, possible doubling on all letter and numbers of obverse, weird striations on the back of his jacket and between there and LIBERTY as well as below the bust up to the rim. Would a worn die cause all this or is something else going on here?
Zinc, worn die, grease, etc. Nice but nothing real special. For one cent I'd throw in a flip and keep.
