It’s also about the stories, history or sentimental value that items hold,” Ken Goldin, a well-known authority in the collectible market and head of Goldin Auctions, said. “Collectibles aren’t just about being old, rare or expensive. It is both a puzzle and a potentially gainful game, making millionaires of some people who finally looked through that dusty box in the attic. That hard-to-define quality is what gives the collectible market its wide appeal to people of all ages. But how do you define what makes an item truly a collectible? A collectible can be old, it can be expensive, it can be a limited-edition-but those elements don’t guarantee something will actually be valuable. Collectibles are desirable objects that people want to own, like a classic car or a piece of fine art.
