you are weird. I have a collection of comic books, and magic:the gathering cards. I tried to get into collecting stamps but way too boring. My dad collects paper money.
Nah, I collect money. Old coins and bills, or money from other countries. Got a decent size collection (got a box of like 15x10x3cm that's packed), though not no many rare items.
Whoa! 50 Ken Dolls? Interesting. My Ex has a pristine 1960-61 vintage Barbie and Skipper w/Blue clamshell carrying case with ALL the accessories, including pet Dog(anyone know Name?)
I was collecting Magic: the Gathering cards, but when they started to release an expansion set a week(Slight exageration) it became too hard to keep up so I said the Hell with it and sold off the whole collection.
Still a great strategy Game though...
I also have a small (At present 7 pcs. and growing) collection of Collector Cat Plates, you know the numbered, limited firing Ceramic thingies.
