Abstract: An Internet based collectables management system includes a plurality of users each of which operates a store. Each store facilitates inventory tracking, trading, transactions, online pricing, and valuation of collectables. An inventory list provides user selectable transaction option such as: For Sale; For Trade; for auction; and for display for each collectable. Interaction specific to collectables is facilitated thereby. The collectables are not necessarily offered For Sale or trade. The collectables may simply be displayed in a users store to stimulate browsing and interaction with other collectors. The system contains a complete reference digest of all collectables. The reference digest allows users to search and browse through a large database of collectable to find prices and information of known boxes, sets pack or other related collectable. As transactions take place within the system the reference digest is updated. Valuation within the reference digest is also updated by users input.
