Description
Fan-Grade, display-ready Miami Hurricanes helmet—autographed and signed memorabilia authenticated by Beckett (BAS). Clinton Portis powered Miami to the 2001 National Championship before launching an NFL career that included the 2002 AP Offensive Rookie of the Year award. A two-time Pro Bowler with 9,923 rushing yards, Portis remains one of the most productive backs of the 2000s.
Collector's Highlights:
- Athlete: Clinton Portis
- Item: University of Miami 2017 Alternate Black Full-Size Riddell Speed Replica Helmet, hand-signed
- Authentication: Beckett Authentication Services (BAS Witnessed Protection Program) with a scannable QR sticker; Beckett no longer issues serial-numbered COA cards—the affixed BAS sticker is the complete certification
Each helmet was signed during an in-person session and may show natural variation in signature size and placement, which is normal for hand-signed pieces. Backed by BAS Witnessed verification, this collector-grade Portis helmet brings trusted authenticity and celebrates the legacy of The U and one of the NFL’s standout running backs of the 2000s.
