They are present on almost all of the shield cents to some degree Even high grade examples have them. It really depends on how distracting they are. The right kind of luster has the ability to hide them though.
You want to send it for grading? Forget it. You can purchase one already slabbed and graded. IMO.. Yours will grade less than MS66 Here's one on eBay..
I try not to grade any actual Mint State Red Lincoln or "vintage" Lincolns with spots considered to be "Unc. Enough" higher than MS-64. I'm often over ruled on this on the current issues because many came that way from the mint. I say so-what! If a collector wishes to purchase a spotted coin grading MS-66 or 67, I still say so what.
I can honestly say that I haven't ever seen a Bus strike with out them to one degree or another. "Technically" I agree with you, they are distracting and shouldn't grade Gem. on a grading scale though they have to be over looked. A grading curve that is set up the way it is can't survive if the highest grade is a 64.
Coins exist w/o spots so the grading scale is not affected. Dumb children must be graded on a curve so they will feel smart. Coins have no feelings.
I have only found that those exist in some mint sets, and not even all of them. A spotless BS shield cent is rare. @BadThad

yeah, I'd say buy a mint set if you are looking for a good modern coin of any type, it's where the best examples come from, the exceptions being the 2005-2010 mint sets which had a satin finish, in that case, you'd need to find the best you could find from circulation, the mint set ones are graded either as "SP' for specimen or "SMS", or have a "satin finish" qualifier on the label to tell them apart when slabbed so people didn't get scammed on high graded satin finish from those years. Anyways, the best coins are found in the mint sets usually, from bank rolls, there's just not many diamonds out there.
Since 2009 the mint has had issues with black water spots. In my experience, the slabbed coins are given bumps for having "less spots". It's fairly tough to find shield cents without a lot of hits. When you do find one - it seems to have a lot of spotting. For me as a collector, it was an exercise in futility trying to find examples that I liked. I have basically stopped collecting anything since 2009 because of these spots. I just don't like 'em!
I took this coin straight from a fresh roll. There wasn't one coin worth keeping out of 30 rolls I cracked. Thanks Denver!
There is no mechanistic formula like count the spots and divide by 15 but they will affect the grade.
