A pawn shop will give you about 10% of the value of your goods. Internet auction dealers, about 50%. If you would like to keep more of the money for yourself, I think a regular auction house is the way to go. Do you know of a good one in your area?
Someone with an antique market booth is going to be problematic unless they just buy everything from you outright. Otherwise you have to keep track of inventory, sales, what if something gets stolen or broken? Consignment is full of problems.
