This is two (2) Taylor, Smith & Taylor (TS & T) dinner plates. I do not know the name of the pattern, it may be a numbered one. I cannot find any others like it. They are marked on TS&T on the back of the plates. I called them “Atom” because that is what the figure on the front looks like.
One is in excellent condition. The other has a small brown spot on the front. It is hardly noticeable, but it is there. I took a picture of it. Take a look at the photos, and if you have questions, please e-mail.
