I have seen a print in 70mm a single reel go for 300 hundred bucks for jedi. It was faded, scratched and the audio was out of sync due to the original mag track being warped or shrunk.
Their is a fan out there who once mentioned on some 8mm forum that he has a copy in fair condition of the whole movie and screened it in his own home theater for 70mm. I think he said it was the original and not the even more rare special edition 70mm. I think there were only like 2 places in the world that had that one place in the USA i think the egyptian theater premiere, and a royal uk premiere.
Someone on ebay sold an empire print that was almost complete 1 reel at a time. I think the dude was a projectionist at a closed down theater, and they were just going to dumpster or cut up the prints so he rescued them. Even stored in perfect conditions for over 29 years they faded to pink. The great Eastman pre LPP stock,lol.
There were alternate audio takes on star wars 77 70mm, and jedi 83 70mm but not different cuts of the film. Empire 1980 70mm premiere is the rarest because it had alternate audio and was an earlier cut of the film.
Some of that different audio was on the super8mm version of the film and matches up with scenes found on Don Gluts novelization.
