Hi ssf2,
Are there only 4 of these dishes? These remind me of something my Grandmother used to have many sets of, what she called Card or Nut Set. When playing bridge or whist each person had a dish for nuts/candy etc. Often they would have 4 slightly different patterns. Perhaps they are something of the same ilk?

I only have 4. I thought maybe they were a sauce or berry dish, or maybe part of a nut set but wasn't sure about the sizes. They do measure 4 inches to the outside, and from the table to the top they are about 1 inch deep. Look too big to be butter pats to me, as all the ones I have seen are smaller.
I keep looking online for something in the same colors to compare them to, but most of what I find is the gray variety. Seems the green/blue/deep salmon color is rarer.
