You can advertise in the newspaper classifieds, do a local listing on ebay, or check your area for consignment stores (hopefully one that doesn't charge too much for pick-up).

I would first check around and see what items like you have are actually selling for. Look at completed auctions on ebay, prices in antique stores and consignment shops.

Post pictures here, a poster might be able to give you an idea of the demand for your items.
