Probably the wrong forum but will start it here. Everything I understand says that there is a deduction for MS coins without or lacking full luster. What does that mean for a coin graded by a TPG as MS - RD when the coin finally gives up and fades to brown which is apparently inevitable. Would that take a coin graded MS-65 Rd and change the grade to something like MS-63 Rd/Bn and then MS-60 BN as it fades? Jim |

Color is independent of luster- color is a property of the metal being struck while luster is a function of the process of striking a coin. The cold flow process that occurs when the planchet spreads out and fills the dies is what creates the radial flow lines that reflect light in a specific way as to create the shine of luster.
Color should not affect the technical grade of a coin. An MS65 will always be a 65 regardless of whether it is RD, RB, or BN. Gem grades have more to do with the special care a coin receives through the years. Think about it- it is very difficult for a coin to achieve a grade of MS66+ unless that coin was cherished and protected by multiple owners over the years. Because of that special care, a copper coin would be more likely to be in a neutral environment that would keep it from toning/patinating.

Jim, the grade would change from MS65RD to MS65RB to MS65BN. There are coins graded by TGP's to be MS67 Brown.
You do have me wondering if an MS68 or MS69 Red coin would maintain that high a grade as it changed color.

Guys,
I agree that you can have a red coin with deminished or no luster, I guess, but I have never seen a brown coin with luster. Part of the grading process by my books is adding or subtracting for luster. so, a MS graded voin should have been considered for luster and when that is gone would not the grade change?

Excellent answers so far!  Jim, a brown coin can still have luster. Especially on an MS coin. I've seen MANY brown coins that cartwheel strongly. I just sold that 1909 to Dave, it had TONS of luster under the brown. There's no point deduction for a brown coin, it's just labeled as BN. However, there is definately deduction for impaired or no luster. In my experience, graders are more sensitive to luster than any other factor. A blazing coin will receive a higher grade based on how bright it is, then the other factors come into play. Luster/Eye Appeal are NUMBER ONE in a graders eyes.

if you look at PCGS's pricing website, you'll see they include varying prices for RD, RB, BN up into the MSs, particularly up into MS 66.

I guess where I am going with this and from the posts I think I know the answer is; if a coin in a big three TPG slab is graded MS-65 RD and has started to turn color to RD/BN or BN, if regraded it would retain the same grade and be assigned an appropriate color designation, in theory. Correct? Jim |

In theory, correct.
If you submit a coin back immediately (same color, same condition), it might receive a different grade. But that is another subject altogether.
