Vintage Hobnail Juice Tumbler Glasses Clear (set of 6)

6 vintage clear glass hobnail juice tumblers 4" x 2.5" Hobnail on the bottom also From what I see on-line, this pattern looks like Fenton, but that is a guess. I can't seem to find a pattern that has the hobnail on the bottom also. 3 are in very good condition, 3 have a few scratches, all look clean and unused, however there are marks scuffs probably from handling over the years. They are old, but not sure how old.
