Most every home in America has had them. Those blue, pink, multicolored or patterned glass bowls and casserole dishes; the ones that your mom, aunt and grandmother used in the kitchen for decades. They could be worth some dough!
Online, you can find many sets or pieces available. Prices range from a few bucks to hundreds; the pink Gooseberry design is still quite popular and the most expensive.
If you’re thinking of turning a profit with them, it might be worth stopping at a few yard sales or going to second-hand stores to find some once-loved Pyrex kitchenware.
Personally, I could never part with my mom’s old Pyrex mixing bowls and casserole dishes. Lots of goodies, delicious meals and memories were created with them.
