Only thing I know is I have seen it before many times, usually the saucers or a cup ,sometimes teapot minus the lid & sometimes just the lid. Any markings on the bottom? Is it child sized or for adults. Kids stuff is often worth more.

Everything is 'worth something"....but also your set is missing 3 cups, the creamer and sugar bowl and the pot has a chip.....and it's not one of the more desireable patterns.
So...the answer is yes it's worth 'something" but not a lot. You might get more if you sold just the 3 cups and saucers one at a time.

Look on ebay for lustreware or lustre ware or luster ware or lusterware, & MIJ or made in japan or occupation or occupied japan.

It isn't real expensive, but collectors often need pieces to complete their sets.

I love that stuff!

Linda is right sell the 3 cups and saucers as a set of 3 and then sell the rest by the piece,if some one is missing a cup or saucer you have a better chance of selling them, the tea pot spout has a good size chip in it, but the lid if in good shape is worth more than the pot.
