Hmm....
Gold - 200 each; the amount you'd need for 99 is incredible so 200 is a fair price)
Crimson - 500 each; most people use this method to get 99 summoning and there will be a high amount, due to waterfiends dropping so frequently)
Green - 700 each; not widely used, however good xp. Not very common though)
Blue - 5000 each; everyone will want these. If you want enough for 99 summoning, the charms themselves will cost at least 80m, now with the tertiary ingredient that's atleast 200m if you want to fast track it.
