Someone who knows anything about pawning?

unfortunately pawn dealers are sketchy. You probably won't get any more than $50 for all of those things together. Ebay wouldn't be your best bet either. The CD player and the speakers cost too much to ship, which is always a turn off to perspective buyers, and you probably wouldn't get much more than the pawn shop would give you. The best idea would be to put an add in the paper. But if your issue is time sensitive, then you should just take them to the pawn shop.
