Good choice 
I’d take any props from the Rocky Horror Show.
Let’s see, I’d like:
Facehugger in a Jar[sup]TM[/sup] from Aliens.
The monolith from 2001: A Space Odyssey.
Jedi training shooty ball from Star Wars.
Han Solo’s blaster from Star Wars.
Original cylon gear from Battlestar Galactica(1979).
The Staff of Ra from Raiders of the Lost Ark.
Skeletal terminator arm from Terminator 2: Judgment Day.
That should hold me for now…
Can I have the animatronic T-Rex from Jurrasic Park?.. That would scare the crap out of people trying to sell me stuff at my door…
Sorry, Indy snapped it in half.
I’d love to own the ‘Mad about the Boy’ cigarette case from Sunset Blvd.
DAMMIT! I wanted that!
DAMMIT again!
I know… Harry Potter’s wand, and the note saying I’ve been accepted to Hogwart’s.
Me, too. I have a duplicate, made from the same mold, but I want the original. Either one of them; it seems Bogey damaged one during filming and they had to bring in the understudy.
The zombie shotgun from Day Of The Dead so we can kill this zombie thread.
The mock-up of the fighter from Space: Above and Beyond -------- the one the Russians spotted and mistook for a real secret government project.
Say what?
Some Soylent green chips…is that weird of me?
Sonny’s bullet-riddled car from The Godfather.
What the hell, throw in Clyde Barrow’s bullet-riddled car as well.
I got a thing for vintage bullet-riddled cars.
mmm
A few years ago I went out with a woman who had all kinds of stuff like this. Not props, per se, but interesting parts of the sets. She’d go out and buy interesting things, put them on the sets of movies, and she’d get reimbursed for them. She was usually allowed to keep stuff that she liked. Her apartment was decked out with all sorts of cool stuff.
Having said that, a phaser from any Star Trek movie.
They made, or had made for the pilot, a basically full sized model of a Hammerhead and were having it transported under all kinds of secrecy and security to where the filming was being done. Somehow someone friendly to the Soviets got a couple pictures and reported it back as some kind of secret US aircraft project. At least the cast claimed in interviews afterwords and the press, at the time, backed them up.
Soylent Green - the taste differs from person to person.

The Tardis, inside and outside. And I want the inside IN the outside, not separate like it is on set
Pulse rifle and Cargo Loader from Aliens
Vin Diesel’s goggles from Pitch Black
Doc’s scoped Winchester from BTTF3
A Dalek
The Chachapoyan Fertility Idol from the opening of Raiders.
A Horgon from ST: TNG
I would say the spoon from the Matrix but as we know…there is no spoon.
