Why people collect trading cards

In 1952, Topps printed a baseball card featuring a twenty-one-year-old New York Yankee named Mickey Mantle. In 2022, a PSA 9 copy sold for twelve and a half million dollars. That seventy-year arc from a piece of cardboard in a wax pack to the most expensive trading card ever sold contains almost everything you need to understand about this category. Cards capture moments

A rookie card freezes the beginning of a career whose outcome is still unknown. Years later, when the career has resolved into greatness, the card becomes evidence of having known something before everyone else did. That retroactive validation is a large part of what the market prices. The other part is condition

The difference between a PSA 8 and a PSA 10 of the same card can be a factor of five in value. A card that survived seventy years in a condition that looks essentially perfect is genuinely rare in a way that a rare stamp or coin is not, because nobody was handling stamps and coins in schoolyards. The combination of scarcity by survival and scarcity by significance is what makes the top of this market extraordinary.
