This is a mint green plate with a cobalt blue rim. No chips, just marks (see pic 3) grey marks from metal utensils.
This would make wonderful vintage decor, or under a plant. It would even still be okay for using to eat or serve food from.
Measures about 9.5 inches in diameter and is about 1 inch deep, great for stews and baked beans :)
Made in China in the 70s
