I've been trying to sell this set of 4 china cups and saucers. The mark on the leads me to believe that were made about 100 years ago. I first priced the set at $15 an no one was interested. Then I lowered the price to $10 and still no takers, even the local tea shop (I sent them an email with the photo and the proprietor said they would be a nice shelf decoration for the shop, but when I brought them in, she said she didn't want them). Am I expecting too much?
