Hi Theresa

Thank you for contacting Mearto with your appraisal inquiry.
Noritake was one of the most popular names for dinnerware in the mid 20th Century; not only was it handsome and serviceable but it was also comparatively affordable. Increasingly few people today, however, entertain in such a formal way and the market is saturated with services of varying sizes, colors, etc. Because there is less demand than supply, fair-market / auction prices for Noritake remain low, typically bringing $4-8 PER PIECE.
While you have a relatively small service with few serving pieces (platters, tureens, serving bowls, etc), the fact that you have the same (and even) number of place pieces (plates, bowls, cups), benefits its value, which I've appraised at about $6-10/piece
Based on the photos and information provided, and subject to examination, this is:
