P C on 5 Bizon Tournament Tokens and some other stuff

I got 5 bison tournament tokens for salen and I don't know how much to ask for them (you can buy a crown with it)

and i would like to know how much summoning stones are worth

The Bison thingies are really dirt cheap, I doubt you can even get 5k for them - very easy to obtain and people usualy just give them away.

Summoning stones... what kind? They range in price from 2-300g to 3-4k. I will go on a limb here and assume you mean mysterious and merchant: myst are 2-300g, merch are 4-500g.
