How much is my China worth?

We couldn't tell you this, even if you gave more detail. There are multiple patterns, and you don't even mention age. Check Ebay is my only suggestion, to see what a set sells for there.

I agree with Tickle. Its only worth what someone else is willing to pay you for it. Ebay is a good judge, but remember, just because its listed doesn't mean anyone is willing to pay that price. Many items never sell because they are over priced.

Ebay can show what has sold recently, using Advanced Search.

I tried to sell a Noritake serving dish once - no bids.
I can tell you how to list china on ebay, but it would take all day.

Take yours around to local consignment shops.

Far too many unknowns. I sold my mothers 1939 set in Craigslist for $125. Not a whole lot of market.
