Radio-Kan in Akihabara has a number of neat rental box stores. These stores rent out clear lockers for anyone to open up their own store. People fill the box with old toys, rare collectables, or even hand crafted models then put on price tags.
The store will take care of the transaction and then give you the money from the sale.
Kind of like a physical eBay.
Great place to look for rare ltd edition anime goods.
