KitKat420,
You said you live in PA, are you in or near a large city? If so there should be several reputable fine art auction houses near you. This would probably be the best return for you and the safest, as you will be dealing face to face. The drawback is that you have to wait for the auction, and then wait again for the purchasers to pay for the items, and then finally you get paid. Another drawback is that the auction fee is generally around 20% for you and the buyer pays about the same. They will also probably want to do the sale as a lot, which will lower the per piece price. I might mention that you risk if the auction goes over 5k then you have to pay income tax to uncle sugar on the proceeds. All in all though, the final net outcome usually exceeds anything you will get on feebay or CL. You can also set a reserve price. I do this on my high ticket finds and have usually been pleased with the outcome.
