If you are keeping toys thinking they are will be worth something some day, skip to 20 years from now and throw the crap away. I hung onto stuff for years, moving it from place to place before finally pitching most of it. Unless it is basically in pristine condition, as in, never played with. It isn't worth squat. I held on to GI Joes, Erector sets, Legos, books, Matchbox cars etc. until wayyyyy too long thinking they would either be worth something, or my kids would want to play with them. Well guess what? None of it was worth anything and my three daughters had little interest in playing with my 30 year old raggedy GI  Joes. About the only things I have continued to keep are my Matchbox cars, which sit in the attic in a sealed box, and my Legos and Lincoln Logs which we actually pull out and play with sometimes. Purge it.

its best just to pitch stuff now, if not you will end up like my grandmother with just completely random junk for 65 years. it might be hard to do it at first but once you get started you will understand why you need to get rid of it.
