As gold itself does not oxidize it is either in the metal mix with elements that do oxidize, or as Broadstruck states it can tone from exposure to mercury.
To me yours looks like it got its toning from album storage.
I like it and NGC thinks it's natural or market acceptable.

You certainly find some beautifully toned gold! I dig it!
Looks like a great looking QE, JW.
'dude
Do I see a D?
No, but I sure wish you did
I normally like your coins but I'm on the fence about this one.
Blues and reds on seen gold are mostly a chemical reaction from exposure to mercury and not toning.

Would PCGS not grade them with this color? It is more purple in person, and I have several graded by both companies with similar color.
And for what it's worth, Doug Winter thought the color in my Avatar coin was natural, and it has the similar look.
Nice addition!
