Any information on 6 pressed glass plate with the words "Honi soit qui mal y pense" in a circle around a cross?

I 6 plates of glass that has a pressure of 8 points form the words "Honi soit qui mal y pense" in a circle around a cross in the center. It appears that the "GARTER" referred FOR REAL MEN of the Garter. I know what the words mean and where it originated, I guess what I'm asking wo know is if someone made these boards, why, what their age, and what may be worth?

shame on he who thinks ill of it
