Quoted from davewtf:
Those games will be easy to sell. Don't stress on it. Selling on pinside is the easiest and best way to get top dollar.
Top dollar? It might be easier to sell on pinside as you know that you're likely dealing with another collector who has the same passion for pinball that you do (with a few exceptions like Choggard).
However, I think most of us are looking for great deals and in my opinion great deals and top dollar generally don't go together.
