AI Appraisal Estimate

This is a Riddell Speed series mini football helmet, specifically a replica of the Dallas Cowboys' iconic headgear. The helmet features a metallic silver/grey polycarbonate shell, a grey plastic facemask, and white chin strap hardware. It is decorated with the classic blue and white Dallas Cowboys star decal on the side and a blue-white-blue center stripe. On the side of the shell, above the star, is a hand-signed autograph in black permanent marker by Pro Football Hall of Famer Bob Lilly, which includes the inscription 'HOF '80'. The helmet is housed in its original clear plastic retail 'clamshell' display case, which bears a red 'SPEED' sticker and an official NFL hologram sticker (serial LA734266767) on the lower corner for authentication purposes. Internally, a small Certificate of Authenticity or manufacturer card is visible behind the facemask. The condition appears to be 'New In Box' (NIB) or 'Never Removed From Box' (NRFB), showing no visible scuffs, yellowing, or fading. The autograph is bold and clear with no signs of ink bleeding or smudging. The craftsmanship is typical of high-quality Riddell miniature collectibles, utilizing authentic decals and scaled-down versions of professional safety equipment materials.

I have completed a visual examination of the Bob Lilly autographed Dallas Cowboys Riddell Speed mini helmet. The item occupies a high rank in terms of preservation, appearing in 'New In Box' condition with no UV-induced yellowing or decal lifting. The autograph is executed in black permanent marker and remains bold with no fading; the addition of the 'HOF '80' inscription increases market appeal compared to sig-only examples. Bob Lilly, 'Mr. Cowboy,' remains a cornerstone for Dallas collectors, maintaining a steady floor for his memorabilia. Market comparables for authenticated Lilly mini helmets generally trade in the $100 to $200 range. The use of the 'Speed' style shell—a more modern silhouette than the 'VSR4' style—adds slight contemporary appeal. The presence of the NFL hologram (LA734266767) suggests legitimate licensing, though it primarily authenticates the helmet rather than the signature itself. Limitations: This appraisal is based solely on digital images. While the signature exhibits the correct slant and 'L' loops characteristic of Lilly’s hand, I cannot verify ink depth, pressure points, or the absence of a 'pre-print' or 'autopen' without physical inspection. For a definitive valuation at the higher end of the range, an examination by a third-party authenticator (JSA, PSA/DNA, or Beckett) to provide a full Letter of Authenticity (LOA) is required. Full authentication would also involve verifying the internal COA card against manufacturer database records to ensure the hologram matches the assigned player.
