This is a 10″ Homer Laughlin, Coventry, Casualstone, dinner plate.
These pieces were all produced around 1970 by the Homer Laughlin Co., for Coventry, who then distributed them as their own. They were made using the Homer Laughlin, Fiesta, molds. There were a few original pieces added to this pattern, but for the most part, including the antique gold color, they are the same as HL Fiesta.
I have eight (8) of these dinner plates for sale, each one separately. They are all in very good, used condition.
Take a look at the pictures, and if you have any questions, please e-mail.
