This is a 2019 Topps Allen & Ginter Pete Alonso rookie card signed in bold blue ink, featuring the Mets slugger during his breakout rookie season. The autograph has been professionally authenticated and graded a Gem Mint 10 by PSA/DNA, confirming the signature is flawless, while the card itself is not numerically graded.

The card is encapsulated in a PSA/DNA holder for long-term protection and display, with certification number visible on the slab and verifiable through PSA’s database. The Allen & Ginter design gives this piece a vintage-style look, making it especially desirable among collectors, and Alonso’s strong, clean signature adds to its appeal.

A great collectible for Mets fans and investors alike, highlighting one of the premier power hitters of his generation with a top-tier autograph grade.
