PSA
Prostate-specific antigen (PSA) is a protein produced by prostate cells and serves as a blood biomarker for prostate cancer screening and treatment monitoring. Its measurement carries noise, which affects the timing of treatment decision triggers and dose adjustments.
Timeline (last 90 days)
Cards encapsulated by PSA are called "slabs," and each slab bears a unique certification number that can be checked for authenticity and grading records in PSA's official online database.
Last week in Santa Ana, California, a FedEx truck parked outside PSA headquarters was burglarized, with more than 200 packages containing graded trading cards stolen, worth more than $963,000 in total.
PSA's grading system uses a 1-to-10 scale (some subcategories carry decimals, such as 9.5), with higher scores indicating better card condition.
Neither PSA nor FedEx has issued a detailed statement on the matter.
The stolen packages all contained PSA-graded Pokémon cards and sports cards.
The same card may be worth only a few hundred dollars ungraded, but after receiving a PSA 10 (Gem Mint) its price may multiply severalfold or even tens of times, and top grades of rare cards can even fetch hundreds of thousands of dollars at auction.
Third-party grading services such as PSA (Professional Sports Authenticator) were overwhelmed with authentication requests during the card revival boom.
