From vampire kits and T-Rex teeth, to pink Cadillacs and hot air balloons, Auction Kings is where one person’s trash becomes another’s treasure. Buyers in the Atlanta area searching for those one-of-a-kind items — a vampire hunting kit, anyone? — know exactly where to go, but the quantity is always limited and the prices fluid. “Auction Kings” follows the action at Gallery 63, a storied auction house in Hotlanta with a reputation for selling both bizarre and high-end items. Its owner, Paul Brown, manages his feisty staff and mingles with his customers, bidders and buyers who come from all walks of life.
