dumb question about hairlines on morgans

SurfinxHI

Can you get hairlines on a Morgan (a bunch) on an MS coin only in the fields and not on the devices (eg, cheek, eagle). I think I have a PL coin, but the fields are all hairlined. Lines seem to be going in multiple directions, mostly vertical though (not X'd or + style). What is the difference between cleaning leaving hairlines and die-polish marks? If anyone has pics, I'd appreciate it.

Thanks in advance,

edited to add: hairlines are only visible under magnification (about 5x, and positively at 10x).

Without photos, you may be describing die polish lines.

Die-polish marks are raised---they result when coins are struck from old dies that have been polished (this leaves hairlines in the dies, into which metal flows from a blank/planchet, resulting in raised lines on the coins). These are mint-made, and should not affect the grade.

Hairlines appear on the surface of a coin as a result of careless cleaning. They are not considered mint-made marks, and will affect the grade (they are a key reason for the net grading of proof coins down to grades like PF62-64). In many cases, the extensive hairlining will result in no grade ('Genuine') by a TPG.

Field hairlines stop just short of the design elements, while polish lines run all the way up to the elements, and usually continue on the other side.
Cleaning lines won't be inside letters and dates but die polish lines will.
