Thank you for contacting Mearto. This is a Japanese dish set for 8, probably Imari ware for export. It matches dishes made during the Edo period. A single plate from this era can sell for around $100. An 8-piece service of 50 pieces is very valuable. The Fair Market Value of the set is between $4000 and $6000.

I am including links, just for visual comparisons of edo dishes. They have asking prices, not sales results.
