Enameled Iron Pots, Pans and Casserole Dishes
Blue usually sells better than other colors—people just prefer it," says Tom Baker of Dig Antiques. It's in even higher demand when the particular shade is hard to find: Le Creuset discontinued its Azure Blue enameled cookware, and those looking to complete their collections are willing to pay extra. A 3-quart covered casserole dish in the deep sapphire color recently sold on the site for $195, while a similar style sells for $100 on LeCreuset.com.
