You have a set of Noritake of Japan porcelain made in the Naomi pattern. There were three Naomi patterns, so the 674 helps in determining which one you have. The pattern was first introduced in 1933 and was continued into the early 40's until the war. A set of 40 to 60 pieces including serving pieces has a current value of $1100 to $1300.00. This is a retail price that you would get if trying to sell yourself online or privately.

You just have to ask because the value could be for insurance, sale or just curiosity. You can sell this set by putting it on consignment with a local auction house. I say local in a general term because they don't tell us where you are. The auction house will sell for you, and you will get a check 14 to 45 days later for the hammer price minus a 20% commission fee.
