To what extent if any does the color of a copper coin affect its numerical grade given by PCGS?

EAC grades do not explicitly label the color but a red coin gets additional points toward a perfect grade of 70. Since PCGS does currently label the color does that imply that a full red coin does not get a bump in its numerical grade because of its color?

Ummm, I don't think that's what he's asking
...But I do agree
As to the OP's question, I don't believe, and have never heard, of a copper coin getting additional points
based on color, rather just strike, surfaces, etc. dictating the grade.
The color does make a difference in the grade too, especially at the higher end of the scale. Based on the pop reports it seems much much harder to make a 67BN or 67RB than it is to make a 67RD. And I haven't seen too many, if any coins graded 68BN, 68RB, 69BN, 69RB, 70BN or 70RB coins. So either a BN/RB coin with no marks doesn't exist or the color of the coin keeps a coin from grading higher?

A BN copper wouldn't be above MS6x (maybe 65) and RB had limits too

<< <i>PCGS stated that they thought it would be HIGHLY unlikely that a brown Lincoln cent would ever be graded higher than a 66 by PCGS. Check the pop reports and tell me how many 67BN Lincolns that you see? The answer is zero.

Actually there are 5 Lincoln 67BN's, though the five are post 1982. Only 4 Lincoln MPL are 67BN. There are also 7 Memorial Lincoln's in PR67BN and 1 PR68BN.

If they do, in fact, drop the RB and RD labels, I think the only way to market grade the coins would be go to the EAC way of thinking.
However, the next logical step is that they would have to do away with the grade guarantee as a result.
After all, if color is factored into the market grade, and PCGS admits they can not detect dipped copper nor are willing to step up to the liability, then the grade guarantee for copper may be the next step in this slippery slope.

In mid and Late-date Large Cents there are 12 coins given MS67s by PCGS. One is red and 11 are Brown.
In post-1864 Indian Cents there are 85 coins given MS67. 84 are red and 1 is brown.
In wheat Lincoln Cents there are 10156 coins given MS67. 10,098 are red and 58 are red/brown and 0 are brown.

I have a couple of RB67 wheaties. HRH viewed one recently and said "RB67...we don't do that anymore". Hmm.
