I recently inherited a 12 piece Noritake China dish set. 12-dinner plates, 12-salad plates, 12-cups, 12-saucers, 1 serving dish and 1 serving bowl. On the back of the dishes it says ROSAY and the # 6216. I am interested in knowing more about these dishes. Is there a story behind the china set and what is the value of the set? Any help/feedback would be greatly appreciated. Thank you!
