I have complete 12 serving set of Noritake China 5029 purchased 1952 in Japan.
what is the approximate value?

Go to Replacements, Ltd. (http://www.replacements.com) and search you pattern - they have the prices for several pieces listed. The service was manufactured in 1950 and is discontinued but still available from these discontinued china dealers. Fine china is priced by the piece not the set so you have to look up the pieces you have and add it up.
