Federal Glass luncheon plates Pioneer pattern

Thick glass plates weighing around 1 pound. Pioneer clear pattern with sawtooth edge. Fruit design in the middle. Pre-owned in good condition. Minor wear, a few scratches from use, and one plate has what I call a bubble. It isn't a chip or crack, but its raised. It is shown in one of the pictures. No chips or cracks that I could find. Please ask if you have questions.
