How a squad of self-appointed experts quietly took over the billion-dollar autograph industry:
Today, few autographs are bought or sold without the blessing of either Professional Sports Authenticator (PSA) or its competitor, James Spence Authentication (JSA). The two companies have come to dominate the market, verifying hundreds of thousands of signatures each year.
Business is so good that they use garbage cans to hold the cash they collect from reviews at hobby conventions. EBay, the world’s largest facilitator of memorabilia auctions, endorses both companies to its customers. Nothing seems beyond the scope of their expertise, from Frank Sinatra’s scrawl to baseballs defaced by Mickey Mantle.
