Yes, they were sold under a number of different brands, and are often sold on ebay by people who have no interest or knowledge of old school BMX, and think they are valuable. That’s the polite answer. Another answer is they are sold by untrustworthy con-men who are flipping something they’ve paid £10 for, and are trying to pass it off as something it isn’t. In other words, avoid, and don’t get ripped off.
