Powered by collectors worldwide, hobbyDB is building a giant database of every collectible ever made from diecast cars to action figures to comic books to corkscrews. The database powers a collection management system where users can upload images and record data about their own collectibles to keep track of them. There is also a marketplace where users can list their items for sale with just a few clicks, build wish lists and receive alerts when stuff they want to buy goes up for sale. It's a whole collectible ecosystem!
