I've been gathering information on these cards since they're so hard to figure out, and while there's still more to do, this is evidently the primary source of confusion: The uncut sheet
Note the differences: The back is brownish, more of a typical cardboard color. There are gaps near the corners of the frame/text box that is located near the bottom of the back.
The uncut sheet is the problem because most of the counterfeits we see contain the dotted cut lines on the front and the text box gaps on the back. The backs are not the correct color, that is brownish. The reprints we see were cut from reprinted sheets with the whitish backs we see on authentic, machine cut singles. At this point, I really think this is the reprinting problem, and I would not buy a Fro Joy single that had the uncut sheet characteristics. If a single was cut from a sheet, it would be evident, not questionable. In the information I've found, Repli-cards reprinted the set with the solid text boxes, and that's it.
Some people think all Fro Joy singles were cut from sheets, but that is certainly not correct.
The sheet is at least as rare as the premium, and it should be safe to assume that people left their sheets in tact back then. I mean, heck, they had to send six singles in for the sheet and/or the premium, so why cut the sheet back into singles?
