Information needed Cup #10 Chinese mini Vase?

I previously posted the just marks on a few of these, so sorry for duplication. An old friend of ours gave us 10 little tea cups as a gift. Story is they all were acquired in Japan during the occupation and brought back to the USA by his Grandfather. I took pictures of the sides insides and the bottom showing the marks, if any. I am posting these one at a time so I can keep the information I receive straight in my mind. Any information you can provide will be greatly appreciated, including possible age, location made, and if it would be worthwhile to contact someone to give a value. These pieces do not have sentimental value, and I would like to sell. If you could give a reference on someone who could provide this service that would be great as well. Sorry to be so long winded LOL. My pictures are large files and I am having to resize as I go so it will take me a few days to post each cup. I thank you!
