Should There Be A Premium On Toned Coins Like RB RD Cents ?

Toned coins generally sells for more if the eye appeal is there (and of course, that depends on the buyer). In the case of RB or RD cents, these aren't so much about toning, but more about preservation. All cents to my knowledge start out red, and eventually become brown (if constantly exposed to air). And so I think that's where the premium for red cents comes from. It has eye appeal, but Its also more of a preservation thing

Just my opinion. I do love toned coins, but it'd be hard to put a price on

As stated, toning is so collector specific as to desirability that it would be impossible to list toned coins as a separate value. NT iridescent bulls-eye toning to black carbon measles.

Most love the first and hate the second.

There are also those who seek nothing but screaming white.

I will happily sell you toned silver at a premium

Other than preference/eye appeal, I hope it does not sell for a premium or become a classified category. It will only further the artificial toning/playing with surfaces of coins. I'm still a little cloudy on what natural toning is, it seems like a better categorization would be intentional vs. un-intentional toning, given that there are so many factors that cause toning.
