About PSA and PSA/DNA

Professional Sports Authenticator (PSA) is the largest and most trusted third-party grading and authentication company in the world. Cards and collectibles graded by PSA are worth considerably more than those that are not – and for good reason. As the grading standard of the industry, PSA is the preferred choice of collectors, dealers and auction houses worldwide. Founded in 1991, PSA has processed over 20 million cards and collectibles with a cumulative declared value of over a billion dollars. Each month we process approximately 100,000 submissions from hobbyists who are serious about maximizing the value of their collections. By providing the advantage and protection of impartial, third-party grading, PSA has created a market in which collectors can participate with complete confidence and trust.

PSA/DNA is the world's leading third-party authentication service for autographs and memorabilia. PSA/DNA Authentication Services was founded by PSA in 1998 in response to widespread counterfeiting, forgery and piracy of autographed collectibles. Just as PSA grading changed the way cards and other collectibles are valued, bought and sold, PSA/DNA's four-level authentication process has revolutionized the hobby of autograph and memorabilia collecting – making it safer and more enjoyable for all. PSA/DNA Authentication Services has authenticated hundreds of thousands of autographs and collectibles from the worlds of sports, music, entertainment, politics and history, including many of the most valuable of their kind.

Who Says It's Mint? Quality is the Key

Some trading card and ticket collectors have a passion for the vintage greats: Ruth, Gehrig, Aaron and Mantle, while others go for today's heavy hitters, like Pujols, Griffey, and Jeter. Whatever your preference, one rule applies: All great collections are based on the very best quality. But sometimes looks can be deceiving, and it's not always easy to understand all of the nuances of condition.

Why Third-Party Grading Makes a Big Difference

Grading collectibles like cards and tickets can be tricky, and a lot of money often rides on determining the right grade. What if you find out your "Mint" Cal Ripken rookie is only "Near Mint" when you go to sell it? Or, that the "Mint" Ted Williams you're thinking about buying has actually been trimmed? You want to be able to buy cards and tickets with the confidence that they are accurately graded -- and that's where we come in.
