Objects collected either for their investment value or because the collector has a personal interest in the objects. Any object can become a collectible, but typically the most popular collectibles are coins, stamps, antiques, and baseball cards. Often these items have historical value; however, occasionally a new collectible item emerges. Collectibles should be insured to protect against loss.

Collectibles may not be easy to sell because there are few organized places where trades can be made. However, some organizations hold periodic trade fairs where hundreds of people come to trade their collectibles.
