Facts
Research the value of Mickey Mouse items. This will prevent you from paying too much for the item and is an excellent way to recognize a priceless treasure if you are lucky enough to find one.
Auctions
Visiting online auction sites such as eBay.com and Half.com is an effective way to learn the value of this type of collectible. You will learn about items produced in mass that are only worth pennies and soon be able to determine what memorabilia is rare. You can bid on items you desire or sell items yourself.
Warning
It is common to bid too high when involved in the excitement of bidding from an online auction site. Simply bidding on the object gives people a sense of ownership. Set a price limit, and stick to it so that you don't regret your decision later.
Garage Sales
Perusing garage sales is a wise way to pick up old Mickey Mouse memorabilia. Many people sell these items when they are relocating or cleaning out a storage building or attic.
