The wife's maiden name was Halsey, and I think this set was hers when she was a child. My guess is it probably dates from the early part of the 20th century. It is decorated in gilt, pink, iron red and blue. Included are 5 cups, 6 saucers, 5 plates, the sugar, creamer and teapot. One saucer has a tiny rim chip.
Otherwise, everything is bright and looks like it was hardly ever used. This is how you want to find an antique child's set. No maker's marks that I could find. Let me know if you need more photos. Check my other user name laureate.
