Stop what you’re doing and head to your grandma’s house right now – she could be sitting on a goldmine! That vintage casserole dish that holds so many memories may actually be worth a small fortune.

CorningWare, the iconic cookware that was on almost every Australian dinner table in the 70s, is now fetching a pretty penny being resold on eBay – with some sets commanding up to $15,000.

The Spice Of Life is among the most collectable CorningWare patterns, with sellers rummaging through their stashes for the valuable sets. It features a vegetable design with the words: L’Echalote La Marjolaine.

The huge interest and high prices has prompted some sellers to put up their much-loved and memory-filled sets for sale, including this $15,000 listing:

“A very rare and collectable set of CorningWare Spice Of Life dishes complete with the original server,” the listing states. “A much loved and cared for wedding gift from October 1977 brought out only on special family occasions. In beautiful and original condition with only a 44 year history of memories with the one family showing in the dishes’ bones and the server’s aged details. The unique three piece set includes a 2 litre, a 25cm, and a 22cm dish with the original matching glass patterned lids CorningWare was famous for.”

Other rare and valuable patterns include Wildflower which was made between 1977 and 1984 and Floral Bouquet, which was made from 1971 to 1975. One of the most common patterns is the Cornflower, but it’s still been known to attract a price into the thousands.

And there’s plenty of interest in the listings, with dozens of people watching the sales. A listing for a single vintage CorningWare casserole dish in February this year sold for a cool $4500.
