A Rolex Submariner... although I guess thats not really rare... I also have a working 1990 (maybe 1993, I don't know) computer, it's interesting to see how bad computers ran then.
Smoke it? No, you can't roll the paper anymore - far too dry. To be serious, my precious treasures are: - a guitar plec from Richie Blackmoore - a cut-out piece from the original "Monty Python and the Holy Grail" film roll - a working C64 some other precious stuff...
Used to own the Mystery Machine from the Scooby Doo movies. Still own Milla Jovovich's backpack from the first Resident Evil movie. Angelina Jolie's watch in Tomb Raider. NES controllers still in the packaging (plastic wrap and all).
NES and a copy of the first Metroid. Oh and i got like hundreds of floppy disks. i don't know what i'm gonna do with them
Can't really think of anything off the top of my head, I don't really own any rare stuff. I do have a £5 coin though...
Rarest for me? Gotta say my original G.I. Joe when first released back in the late 60's. Its got the unique reversed thumb print (thumbnail faces the palm of the hand), along with the footlocker, clothes and other accessories as well. And I also have over a hundred of the original (first year released) "Hot Wheels" and "Matchbox" die cast cars. (all packed away safely) I've kept them all since buying them as a kid and are well over 40 years old (including my G.I. Joe).
My dad' convinced that $2 bills aren't made anymore, so he's kept this 1954 bill. He has 5 of them. I have every baseball card made by topps from 197...6? sometime in the 70s. I also have every 1969 card except for Mickey Mantle. My favorite is the 1969 Nolan Ryan, and my dad' favorite is his White Letter Willie McCovey (They're usually yellow lettered).
Nintendo power glove Amaing spider-man 300 (signed by T.M.) (venom first appearance) An African cane that no one can seem to tell me anything about....its a pretty creepy thing.
I supposedly have the first 1909 penny that came out of the US mint ( my great grandmother worked there and passed it down...it is covered in glass and never been touched without gloves...it's in beautiful condition
The 1909 VDB? You lucky SOB. I have every mint, every year, every false swipe, except the 1909 VDB.... Dang..
They are. 1% of money bills a year. They dropped in 1966, but then brought it back in 1776(bicentennial).
