5 Yoshi's Island DS plush toys that where never released in Australia and where only made for Japan, and are also available in the US (although the tags are still in Japanese)
Oh wait, now I remember. My dad found a really old medicine bottle in the field. I'm going to take a stab at 1910's about...? doesn't exactly show the date or anything, just a small glass bottle.
I've got this rather large coin made of 99% silver (some strange value like that I think). It's around 5cm (2 inches) in diameter and has a tiny piece of a meteorite inside the centre. The centre is just some glass or something so that you can see the piece of space rock within the coin. There were only 500-ish of the coins made, but each one is unique (different piece of rock) so I guess that's something. Not overly pricey, but in a few years time it's value will probably go up... by a buck or two.
I have a limmited edition Platinum gamecube with the shadow Lugia on it from Pokemon XD Gale of Darkness. Still in perfect condition. I have a few things that are kinda rare actually...like some coins from the Pokemon collectable coin game still in their case.
