San Francisco 49ers running back Kaelon Black and cornerback Renardo Green will sign in person at Lefty's Sports Cards in Millbrae on Tuesday evening, October 6, 2026. It is a small-room, weeknight signing at a neighborhood card shop, the kind of event where fans actually get a moment with the players instead of a rushed handoff at a convention table, and it gives Peninsula collectors a way to add current 49ers autographs to their collections in the middle of the season.
The signing runs from 6:30 PM to 7:30 PM. Each player is ticketed separately, so you can buy a ticket for Black, Green, or both. Published pricing lists a Kaelon Black autograph on any single item at $50 and a Renardo Green autograph on any single item at $40, with inscriptions of up to three words available as an add-on and COA stickers available for authentication. Autographs are authenticated by Beckett Witness. Advance tickets are not required, but the organizers strongly recommend buying online in advance because signings can sell out; remaining tickets may be sold at the store on the day. If you cannot attend, Trifecta Sports Collectibles is running mail-in and helmet pre-order options with deadlines a few days before the signing.
What should you bring? 49ers mini helmets, full-size helmets, footballs, photos, and jerseys are the popular choices, but trading cards are where this event gets interesting for collectors. Rookie and early-career cards from Panini Prizm, Donruss, Score, Mosaic, and college-era Bowman products are ideal candidates for on-card signatures, and a signed card from a current roster player can become a standout piece in a team set. Lefty's is a working card shop, so you can also browse its cases for sports singles, sealed wax, and supplies before or after your turn in line.
The venue is Lefty's Sports Cards at 1859 El Camino Real in Millbrae, right on the main Peninsula corridor. Free parking is available. The shop is a short drive from San Francisco International Airport and US-101, and the Millbrae BART and Caltrain station is nearby for anyone coming by transit from San Francisco, the East Bay, or the South Bay.
This event is a great fit for 49ers fans, team-set collectors, parents looking for an affordable first autograph experience with their kids, and anyone who prefers an intimate shop signing over a large convention floor.
Tips: buy tickets online ahead of time, choose your item before you arrive, and have a blue or black paint pen ready if you are bringing a helmet or glossy photo. Remember that players can decline any item, inscriptions cannot be added to previously signed items, and all sales are final unless the player cancels. Arrive a few minutes before 6:30 PM so you are in line when the window opens. Check Trifecta Sports Collectibles and Lefty's Sports Cards on Instagram for last-minute updates.
