I dont sell even a seed & would never do so again,i'd give my stash away before i sold any of it,it takes too much work to grow & the risk of selling just to make a few bucks is way too high for my tastes.
Be sure you are really ready for what can come down on you should you decide to sell pot,i strongly advise against it.
But to answer your question an oz in my area goes from $90 to $120, depending on the usual stuff like availability & quality.
