1992 Lincoln Memorial Cent Grade?

Ive heard the dke cracks, on front of his nose and right to left from date(?) to Liberty(?), don't increase value but do the decrease it? The flat spots on his head? Thanks for the info.

In order to increase die life and production numbers, the mints were known for using weak die pressures resulting in incomplete strikes. Weakness in the hair is normal for many years of Memorial cents. Another notable year for very weak hair are the 1990 issues, especially the Philly mint. I searched many thousands of 1990's seeking one with full hair!

The reason for this was the constant tweaking of the dies to lower the shoulder relief to address strike issues of the past. They lowered it so much that the new high point of the design became the hair. There is also a lot of die to fill in that area.

Here's my 1992, searched a zillion coins to find this one, check out how good the hair is:

Not only low pressure strikes but a slightly tilted die is to blame. You can tell because the corresponding edge of the reverse received the lack of pressure to fill those devices.

Generally, no but it can when you get to the very high grades, i.e. 66 up. It all depends on how it affects the eye appeal. Remember, most of the grade comes from how a coin looks in hand and a graders first impression.
