potions ~ heal, refresh, str, agil and cure all go round 25k per 500... explo 55k per 500
leather ~ depends on your buyer an invul set can get 125k if u wait and easy almost instant at 75k. fort full sets round 30-40k
cloth ~ not much
bones ~ 100 per i think
gheal light mini heal fireball wands ~ gheal 12-15k per charge, lightning 3k per charge, mini heal & fireball 100g per charge
none of this ^ is 100% fact just my guesstimations
if i were u, if you have a good bit if things to sell, i would just setup a small vendor house and gate to it... start high and adjust lower as the days go buy till you findout what price your shit goes for.
