Frag prices

[michika]

I'm curious to know, and understand, how frags are priced. I want to know specifically about ones traded between hobbiests, and not store purchased ones.

I want to know, for those who've sold, sell, or will be selling frags, how do you come to your selling price?

Granted things like coloration, size, and rarity come into play, but after those are all accounted for how do you set your price?
