10 Old Corningware Pieces That Are Secretly Worth A Fortune (Check The Mark)

Most people think the old casserole dish at the back of the cabinet is junk. It's ugly, the lid doesn't match, the pattern is faded, and the whole thing screams a decade nobody misses. So it goes on the fifty-cent table or into the free box after somebody dies. But after thirty-four years pricing donations in the back room of a charity thrift shop in Dayton, Ohio, Marge learned the truth the dealers already knew: the good stuff never comes in looking good, and the value was stamped on the bottom the whole time. This video counts down ten covered baking dishes from weakest to strongest, and shows you exactly what to flip over and read. You'll learn why Pyrex Spring Blossom Green (Crazy Daisy, 1972 to 1979) and turquoise Butterprint (1957 to 1968) are common while pink Butterprint makes collectors sit up, how to spot the Anchor Hocking mark on Fire-King jadeite, why a scoured Gooseberry (1957 to 1966) loses its money, and how Glasbake by McKee gets confused with Pyrex. Then the top five: Hall's Autumn Leaf made for Jewel Tea starting in 1933 with the Mary Dunbar mark, the 1971 Friendship pattern, the mid-1950s Atomic Eyes promotional, the incredibly rare 1959 Lucky in Love with its clovers and pink heart, and at number one the 1958 Corning Ware Cornflower Blue, whose identical white body also carried scarce patterns like the atomic starburst, Floral Bouquet, Blue Heather and Wildflower. Marge also names every destroyer that guts the value: dishwashers, chips, bleach on crazed ceramic, thermal shock, repainting, and lost lids. The one lesson under all ten is simple: never read the front, always turn it over.
