Professional Model Bat Authentication Process
Our authenticators have a diverse knowledge base that is complemented by proprietary methods and technology to form the following four-step authentication process.
Step 1
Examination
PSA employs the same state-of-the art technology used for autograph authentication to protect your genuine bat from any foul play.
Step 2
Anti-Counterfeiting
Once deemed authentic, the bat is marked with invisible DNA-laced ink, which is naked to the eye but verifiable through a specially calibrated infrared laser.
Step 3
Certification
PSA then registers a unique certification number for your item within our database, allowing the authenticity to be verified online at any point in the future.
Step 4
Documentation
Finally, a Letter of Authenticity (LOA) containing a photo of your bat and specific details on the analysis is created to accompany your order.
