What It's Worth

Every collector asks the same question sooner or later. What's this thing actually worth?

The honest answer is that a signature's worth whatever the next person will pay for it, but that number isn't random. It moves on a few things you can learn to read. How often the athlete signs. Whether the piece is authenticated. What the item is, because a signed full-size helmet and a signed index card live on different planets. And whether the player just did something that made the whole country care.

This section covers all of it. The rarest signatures in sports and why almost nobody can get them. The most valuable autographs ever sold. Which current players are worth grabbing now, before the Hall of Fame call comes. And how the memorabilia market has changed over the last ten years, because it's changed a lot.

If you're trying to figure out whether a piece is a good buy, start here. If you already own something and want to know what you're sitting on, you're in the right place too.
