What's going on here?

this coin is brown, xf-45, if it was for sale would you believe it still has original luster

Then why won't the major TPG's guarantee the color designation?

Unless it is so heavily toned that the toning itself has disrupted the surface topography. Even then it may still have luster, just don't ever remove the toning because the surface will go with it.

It would be listed as brown because most of the original red color is gone, but not all of it. In the protected areas tere is still some red and luster remaining. (On an XF-45 coin it is also possible for it to be completely brown and still have luster in the protected areas.)

 

It seems like you don't understand the definition of "luster". It doesn't mean "metallic shininess". It means "reflectivity that depends on the direction of the light source".

That anisotropic (different in different directions) reflectivity is what causes the "cartwheeling" effect characteristic of luster. Brown coins can most definitely exhibit it, even if the reflections aren't as bright as those from a red coin. It comes from flow lines on the surface, which are so large that they can be seen under an ordinary optical microscope; the surface layer that causes red copper to turn brown is much, much thinner.

You also seem to be under the impression that slabs are air-tight. They aren't. Another member here has told of seeing a coin doctor tone a coin very quickly without removing it from the slab, presumably by sucking the air out of the slab and replacing it with a reactive gas.

 

this is the coin were talking about if you think this coin still has the "cartwheeling" effect I'll sell you some ocean front property, in Arizona

 

If you can tell me how to vary the lighting angle on a static photo, I'll be happy to discuss it further with you.

 

As I said before. There is no cartwheel effect. It doesn't even "flash" at you.

 

sure, the cart-wheel effect would show in any light, just at different angles on the coin, none on this one

 

thank you for being honest

 

Okay, I wrote that poorly. Luster doesn't always produce cartwheeling, especially when it's only present in isolated areas. But, while you can have luster without cartwheeling, you can't have cartwheeling without luster.

And you can have luster showing through toning, whether it's rainbow, brown, or even black.

 

just for the record, no orginal luster, like I first stated

 

thank you too, for being honest

 

Who said no original luster? In the first post, detecto said "appears to have mint luster remaining". Just because it doesn't exhibit the cartwheel effect does not mean that the coin does not have mint luster. Luster can be present in isolated areas rather than the whole coin.

 

for get it, I'm done here, good luck everybody lol

 

Thank you for being patient with me when I'm not writing as clearly as I should.

 

thats ok, I'm far from perfect

 

Exactly.
