Morgantown crinkle driftwood texture green glass tumblers, mid-century mod vintage

MCM vintage barware, a set of six highballs 5 1/4" tall, all in excellent condition. These I think are Morgantown crinkle rather than Seneca driftwood, but to be honest, I find it nearly impossible to tell the two patterns apart! Color is green on the blue side, not really turquoise.
