Certain VHS tapes are becoming increasingly valuable as collectors vie for the most popular and rarest movie titles, and with third-party certification, authenticity and condition are guaranteed.
I have the trilogy unremastered and VHS a new Hope Empire strike back and return of the Jedi that I picked up in a Goodwill years ago. They are not sealed, but I wondering if I got some money here.
Most of those are legit sales, and a sales history to back them up. Maybe you're thinking of the fake Disney "black diamond" hype. That's all fake. Some sealed, poofy clamshell, 1st print (original 1970s and 1980s) can get $1000s though.
