AI Appraisal Estimate

This is a Riddell 'Slate Collection' speed-style mini football helmet, featuring a distinctive matte charcoal grey (slate) finish rather than the traditional team colors. It is part of a specialty alternate series produced by Riddell. The item showcases the Florida State Seminoles logo on the side in a tonal or subdued color scheme, complemented by metallic gold-colored striping along the top and a matching metallic gold face mask. A white chin strap is attached to the lower housing. The helmet bears a hand-signed autograph in silver-white paint pen, likely by Renardo Green given the inscription '#31', which corresponds to his collegiate jersey number at Florida State. The signature appears bold and legible against the dark matte surface. It is housed in its original clear plastic retail display cube, which includes an 'NFL Mini Helmet' base label and a Riddell logo. An official hologram sticker is visible on the shell for authenticity purposes. The condition appears to be 'new in box' (NIB), with the clear plastic casing protecting the item from dust and direct handling. The paint finish and decals seem intact without visible scuffing or peeling. This modern collectible represents a popular niche in sports memorabilia—the matte-finish alternate mini helmet—which is highly sought after by collegiate football fans and helmet collectors.

Based on my visual examination of this Renardo Green autographed Florida State Seminoles 'Slate Collection' mini helmet, I have assessed its current market position. The item is in 'New in Box' (NIB) condition, preserved within its original retail display cube. The matte charcoal finish is free of scuffs, and the silver-white paint pen signature is bold and well-placed, showing no signs of fading or ink fragmentation. The inclusion of the '#31' inscription adds specific collector appeal as it ties directly to Green's collegiate tenure. As a 2024 NFL Draft pick, Green's market is currently driven by a mix of FSU alumni collectors and San Francisco 49ers fans looking for rookie-era memorabilia. The 'Slate' series is a popular alternate style that typically carries a slight premium over standard team-color mini helmets. Comparable sales for signed collegiate defensive back mini helmets with basic holographic authentication generally fall within the $50 to $90 range. The value is currently capped by the player's position; defensive players typically command lower prices compared to quarterbacks or star wide receivers unless they reach All-Pro status. A significant limitation of this appraisal is the inability to physically verify the hologram's serial number against database records or inspect the helmet for 'ghost' signatures or re-applied decals. To finalize authentication, I would require a physical inspection under UV light to check for signature tampering and a verified COA from a reputable third party like JSA, PSA/DNA, or Beckett. Without an accompanying certificate or direct provenance, the valuation assumes the visible hologram corresponds to a legitimate signing event.
