Sent an Alex Bregman signed ROMLB to JSA 8 days ago to JSA in Florida. Got it back today with the 'Signature Debut' Certification.
The Basic Cert says: "This item is certified as 'Signature Debut' and is our considered opinion that the item is genuine, signed before the last game of the signer's official rookie season."
Cert #: SD01017
I went online to verify the code, but it said that it takes up to 3 weeks for it to be entered in the system. There is a little JSA Sticker on the ball too.
