Bobble Heads are also a very good investment, if you know the right bobble heads to buy. i started collecting them a couple of years ago for the hell of it. the key to having a valuable collection is to find and buy them at a low price. for example, i bought a paul molitor 2003 world series bobble head from a old lady at the flea market for $4. that bobble head is worth about a $100. you can even by them at retail price on a hunch. for example, i bought a mac dre thizzle washington bobble head for $20 when it first came out. because i had a hunch. something told me i had to get it, so i bought it. it was a good investment cause its worth a lot fucking more than $20 now.
