IMO your coin looks like it has some Mechanical Doubling on it. Photos of the entire coin would be more helpful. Here's the 1984 Doubled Ear LMC: http://doubleddie.com/828844.html
If you look at the front of Lincoln's face you'll see a flat ledge there (very clear from his neck up to his nose). That is a prime indicator of Mechanical Doubling. You then can see other flat/shelf like indicators in his hair, and the lower part of his ear. If you provide a picture of the entire coin, and look at the entire coin you can learn from what you see in it's entirety instead of just focusing on one specific area.
