There is a particular kind of household box that never gets thrown away. It contains old coins, a watch that stopped working sometime during the previous administration, a stack of baseball cards, strange-looking tools and perhaps a belt buckle nobody remembers buying. The official reason for keeping all of it usually sounds the same: “It might be worth something.”
Sometimes, that hunch pays off. More often, the box contains objects worth less than the cardboard box itself, but a few categories consistently deserve a closer look. The difference between genuine collectible value and garage-sale optimism comes down to age, rarity, condition, demand, and, sometimes, one tiny detail that turns an ordinary object into an interesting one.
