This is a Heisey Coarse Rib, pattern #407, salad plate that was manufactured between 1916 and 1933. It is clear, measures about 7 1/2" in diameter, and marked with Heisey Diamond "H". There are no chips, cracks, or repairs, but may have minor manufacturing flaws. It does have scuffs and scratches due to normal aging and obvious use. Still, it is very nice.
