This dinnerware listing is from McCoy's Graystone dinnerware line and is a service for 4! There is a total of 20 pieces -- 4 cups, 4 saucers, 4 bread/dessert plates, 4 soup/salad bowls, and 4 dinner plates!
The cups are marked 1412, McCoy, Lancaster Colony (mark), USA. Saucers, bread/dessert plates, bowls, and dinner plates are marked USA.
Set is in very good condition with minor evidence of "use". One cup has a tiny ding on bottom rim and has some crazing, 2 of the saucers have tiny dings on underneath rim edge and 1 has what appears to be a pottery flake-off on underneath rim -- bread/desserts, dinner plates, and bowls have minor utensil marks (not unusual on items with clear over-glaze).
Set is in very good condition and I have priced it to reflect the minor imperfections listed above.
I also have a 5th small bowl that has a chip on upper rim side and I will be happy to include at no cost -- you could use it to hold a pillar candle, after dinner mints, etc.
