I think these dishes are Homer Laughlin Golden Wheat fleur de lis 22karat. They are in very good shape. The cups have a couple chips but none of the other dishes do.
10 dinner plates, 8 salad plates, 8 larger bowls, 8 smaller bowls, 7 saucers, 3 of the shorter coffee cups, 4 taller coffee cups, sugar and creamer bowls.
I have no idea the time period and there are no stamps or markings.
