This china was left to me by mt Grandmother. My Mom told me they use to go to the movies here in Stamford,CT and everyone would get a piece. I have about 100 different pieces.
Best way is just look up the pattern on ebay !! That will tell what people are actually paying !! If at all !! China of any kind is in a slump except for very high end pieces !! Even it is slow !! China like yours that was given as premiums is usually plentiful and not expensive at all !!
