Testimonials
What our customers are saying about us.
The importance of grading and authentication in the marketplace cannot be overstated. The services offered by PSA allow everyone to ‘speak the same language’ and make the sale of items quick and easy. We often consult with non-collectors who are unaware of just how important grading and authentication is for the success of their items at auction, and we communicate to them that the investment is a wise and worthwhile one. We consistently notice a premium attached to items authenticated by PSA."
"For us and our clients on both sides of the transaction, utilizing the services of PSA is an important step in the process."
Frankly, third-party authentication and grading is everything. This is what allows me to acquire things with confidence...Every item that I own has been through that vetting process."
When I was buying cards, even as an adult in the early 1990s, they were not authenticated or graded, and it was up to you to inspect them as well as you possibly could. But you never knew with any confidence what you were buying and (if) someone may be scamming you. Now, as someone who has an investment of substantial dollars I would never think of acquiring a card that had not been authenticated and graded. PSA has become the ultimate deciders on giving official identity and value to a card. They provide a great service."
The Hall of Fame and PSA and PSA/DNA have similar passions. We also have similar audiences – those who value the preservation of baseball history and the objects and artifacts that are associated with that history. We see the fans that collect cards and who have their own memorabilia collections come to Cooperstown with a tremendous respect for the preservation component of what we do. Our relationship with PSA and PSA/DNA has helped us give the fans the opportunity to connect with that love and passion. There is a great synergy between those who visit the Hall of Fame and those who collect and use the services of PSA and PSA/DNA. I think we serve a common audience very well."
It is not hyperbole to say that the PSA Set Registry is the greatest tool ever invented for the sport card hobbyist. From tracking, to population, to seeing where other collectors are, what's out there, what exists, what goals can be realistically set, what collectors are doing, trends – the Registry is the greatest gift ever given to the hobby."
