AI Appraisal Estimate

This is a Riddell Speed mini football helmet featuring an autograph from San Francisco 49ers cornerback Renardo Green, inscribed with his jersey number '#31'. The helmet is part of the Riddell 'Slate Collection', which features a distinct matte dark grey (slate) finish rather than the traditional metallic gold, providing a contemporary aesthetic. The San Francisco 49ers 'SF' oval logo is prominently displayed on the side in a muted gold and red color scheme that complements the slate shell. It features a gold-painted plastic facemask and white chinstrap hardware. The item is housed in its original clear plastic retail display case with the Riddell and NFL branding visible on the lower band. Notable professional markings include a 'Slate Collection' sticker on the front left and an official NFL authentication hologram sticker on the lower left of the shell. The condition appears to be 'new in box' (NIB), with the helmet securely mounted on its white plastic internal base. No visible scuffs, paint chips, or fading are present on the helmet shell. The autograph is executed in a bold white paint pen on the upper right side of the dome, showing high contrast against the dark background. This piece represents a modern sports collectible from the 2024 NFL season era, specifically catering to fans and investors of emerging defensive talent.

I have conducted a visual examination of the Renardo Green Signed SF 49ers Slate Mini Helmet. The item appears in 'New in Box' condition with the matte finish of the Slate Collection showing no visible abrasions. The white paint pen signature is crisp, well-placed, and features a clean '#31' inscription, providing excellent eye appeal. Market demand for Green, a 2024 second-round pick, is currently speculative. As a rising defensive talent, his market is localized to 49ers collectors and NFL draft enthusiasts. Recent sales for signed mini helmets of similar rookie defensive backs in specialty finishes range between $85 and $150. The 'Slate' variant adds a premium over standard colors due to its limited aesthetic appeal for modern displays. However, value is capped by the high supply of signed rookie memorabilia before a player achieves Pro Bowl or All-Pro status. While an official NFL hologram is visible, my verification is limited by the digital format of this examination. A final valuation assumes the autograph would pass third-party authentication (JSA, PSA/DNA, or Beckett). To finalize this appraisal, I would require a physical inspection to verify the tactile texture of the paint pen and high-resolution imaging of the hologram to confirm its serial number against official registries. Without a COA from a major authenticator, the market value would likely sustain a 30-40% reduction.
