Alexander Mattison
NFL Running Back · Football - NFL
Minnesota Vikings / Las Vegas Raiders / Miami Dolphins
Era
Active Career - circa 2024 (Dolphins signing period)
Item Type
Trading Card
Condition
Near Mint to Mint (Card); Excellent (Autograph). The card edges appear sharp, though the autograph is slightly overlapping the player name text. The blue ink is vibrant against the white/green background.
Rarity
Common. Mattison is a known willing signer during training camps and public appearances. Signed base cards of active NFL players are relatively abundant in the hobby.
Overall Assessment
A genuine, attractive example of a modern NFL player's autograph on a contemporary card. Ideal for a Dolphins or Raiders team set collector or a fan of the player.
Authenticity Assessment
Highly likely authentic; confidence 95%. The signature exhibits the high-speed, loopy flow characteristic of Mattison's modern 'in-person' style, consistent with his autograph on vertically oriented cards.
Signature Style
Stylized and vertical. It features a large, looping 'A' followed by a rapid, wavy 'M' that descends vertically across the card. This is his typical quick-sign format rather than a full-lettered signature.
Signature Characteristics
Fluid, rapid movement with a heavy emphasis on the initial characters. The signature follows a vertical baseline which is common for athletes signing cards held in a portrait orientation.
Ink & Medium
Blue felt-tip permanent marker (Sharpie). The ink shows consistent flow with no signs of hesitation, stalling, or ink pooling, which is typical for a genuine hand-signed sports card.
Item Description
2024 Panini Donruss football card. The card features Mattison in his Las Vegas Raiders uniform, but the card text explicitly identifies him as a Running Back for the Miami Dolphins, noting he signed with them on 3/14/25.
Estimated Value
$10 - $25 USD. As a non-certified 'in-person' autograph on a base card, value is primarily driven by team collectors and fans of the specific player rather than high-end investors.
Comparison to Known Examples
Matches very closely with late-2023 and 2024 Panini sticker autographs and known in-person examples from his stint with the Raiders. The loopy 'A' is his most consistent identifying feature.
Authentication Tips
Look for the distinctive 'double-loop' at the top of the 'A' and the long, trailing vertical downstroke of the 'M'. Authentic examples should show high velocity (tapering at the end of strokes) rather than slow, shaky lines.
Certification Recommendation
Beckett Authentication Services (BAS) or JSA (James Spence Authentication). Both are industry leaders for modern NFL trading card authentication.
Red Flags
No significant red flags observed. The ink sits 'on top' of the card gloss correctly, and the stroke speed is consistent with a natural human hand.
Provenance Notes
Likely obtained in-person at a training camp, team event, or through a private signing. Documentation of the specific event location would bolster the story, though not strictly required for this value tier.
Historical Context
Mattison is notable for his productive years in Minnesota before becoming a primary back for the Raiders and subsequently moving to the Dolphins. This card represents a transition period in his career.
Market Trends
Stable. As a veteran starter/backup RB, his market remains consistent but lacks the volatility/upside of a star quarterback. Interest usually peaks when he signs with a new team like the Dolphins.
Investment Potential
Low. Base card autographs for non-Hall of Fame players typically act as personal mementos rather than appreciating assets. It is a 'Hold' for a team collector.
Similar Autographs
Dalvin Cook (whom he backed up in MN), Zamir White (Raiders teammate), or Raheem Mostert (Dolphins teammate).
Display & Preservation
Store in a PVC-free plastic top-loader or a 'magnetic' one-touch holder. Keep out of direct sunlight to prevent the blue Sharpie from fading or 'sun-bleaching' into a purple hue.
Interesting Facts
Mattison often includes his jersey number (#22) or a religious inscription (P.T.L. - Praise The Lord) in more formal signings, though he often omits them during quick sessions, as seen here.
