Grading Question?

Do polishing lines (by mint) such as the ones on the two lincolns below result in lower grades?

However, I don't see that these are worth the submission fees.
60 years into this hobby and I'm still working on my Lincoln set!
New collectors, please educate yourself before spending money on coins; there are people who believe that using numismatic knowledge to rip the naïve is what this hobby is all about.
But can not see a Lincoln with heavy polish lines going MS67. They In my opinion take away from the eye appeal
of a coin. And with so few making this grade, a ms67 Lincoln would need to stand out in this way.
