My mother-in-law gave me her grandmothers noritake china.I don't kow exactlyhow old it is but if her grandmother were still alive right now she would be about 100 years old soI would guess the china is anywhere from 80-60 years old. There is no pattern number on it, does anyone know how I can figure out what the pattern number is for my china or how much it is worth? Any help would be greatly appreciated! I can send you pictures of the china if that helps.
