I recommend that you sell your collectable cards in one of two places, on the internet or at collector shows. The almanac at this web link has a list of flea-markets that have collector tables, and collector shows for your entire region, including Georgia.
Also if you go to the following store in Albany, the owner should be able to provide any upcoming events for sport card collectors. You just missed a sport card collectors convention in Atlanta which took place in February.
