Worth? To whom? FOr Insurance purposes or are you looking to sell? If you look on eBay, antique china goes for pennies on the dollar... Seriously - Pennies. In an antique shop, the prices are Much, Much Higher, but then I don't know who pays them and who gets how much of the sale price -- ie consignment.

By "six complete sets," do you mean service for six? Consider keeping extra plates, etc., even if you get rid of the serving pieces. Otherwise, one broken plate will mess up your set. Or you could hang onto everything. The serving pieces will come in handy when you use the service. You're lucky to have two serving bowls!

Margaret Rose is porcelain. However, it is a serving piece. One of the clues is the light weight. If you have the one with the decorative band of gold on the lid and side, that's a decal but is fired on. Then the edge gold is hand painted on and fired. Fired gold is pretty stable but naturally you don't take a scrubby to it. Enjoy your pretty china. [Early on I was a painter for Cybis Art Porcelain. My specialty was animals, especially birds but also the gorgeous carousel animals. We all did anything that was on order too. Figurines, etc. Later I worked as a decoration designer for Lennox, designing the paint jobs for their decorative collectables. Painted for Edward Marshall Boehm for a while too. Anyway, I've painted gold on plenty of porcelain, although not dishes. Smiles. Cybis will always hold a special place in my heart.] Here is a link that might be useful: Cybis latest carousel animal-Reindeer

Thank you all for your wonderful advice! Formerly LanaRoma, I'm lana_roma now. Apparently, my email address was lost during the move, but my old username still remained in their database, although I couldn't get it confirmed even after multiple attempts. I asked the GW/Houzz staff to restore my account but received no help from them. I gave up and got a new account to be able to use GW. Oh well. The point about looking for hand painted vs decal is a great one. Now I'll make sure to have a magnifying glass with me when looking at china. Made a list of brands that you suggested and Googled them. Mottahedeh looks fabulous and very high end. V&B Anmut is such a sophisticated choice! Royal Doulton looks lush and Victorian - wish I had a Queen Anne house to go with it. :-) Spode Stafford is lovely. Lenox, Limoges, Pickard, Wedgwood and Bernardaud are on my list too. There's a lot of Noritake and Mikasa china on CL, but my understanding now is that those are pretty much mid-range brands. I'm confused about Haviland. There are Haviland sets for sale on CL, but some ads say that not all the items in the ad are Haviland, although they all have the same design. For example, this set is lovely: The ad Haviland Set on CL says that some pieces are "Haviland France, some are marked Z.S., & Co. Bavaria, and one is marked Japan", although the pattern is identical. Am I right to doubt whether it's a quality set? I'm a little confused about bone china too. I have two cup and saucer sets of hand painted bone china made in St. Petersburg, Russia. The china is very thin, translucent and with fine detailing. I also have a cup and saucer set marked as bone china and made in England. It's a nice set, but not as fine as the Russian sets. Thicker, a bit clumsier in shape and doesn't look so refined. Funny, when I browsed the local CL today, there were two Mikasa Classic Flair sets for sale. I like my Classic Flair set because I'm partial to Art Nouveau styling, although it's definitely not everyone's thing. Tureens - I use my Noritake Belle Rose tureen to microwave rice pilaf that comes in boxes. Works great! But it's marked as Cook'n Serve. Also, is there a high demand for fine china overall? Some CL sellers ask such high prices for used china. Like $1500 for a Royal Worcester Evesham Gold set: Evesham on CL . This baffles me. I have an Evesham Gold serving dish ( a gift) and it isn't really that high end to me. It's pretty, but not more.
