I have a setting for 12 people and gravy bowl,salad bowl, sugar and creamer bowl of Noritake China pattern number 7527. It has a silver trim around the edges with white flowers and leaves on the plate. How much is it worth?

Your public library has a collectibles book that lists china sets and their value. If they don't have the current book in their collection, ask for it through interlibrary loan or to have that page faxed from the owning library.
