vintage amber glass cup plates, old hobstar pattern pressed glass tiny dishes or saucers

Lot of three tiny little cup plates, amber glass, about 3 1/2" in diameter. These look like butter pat plates, but they have rayed ribs at the centers - so I think they're cup plates / coasters. No rings like you ordinarily see on saucers.

I am not sure of their age. They might be EAPG originals or 20th century vintage reproductions of older pieces, I just don't know. There's no wear or damage to any of the three.
