THE COLLECTION

NFL-San Francisco 49ers

Authentic San Francisco 49ers Autographed Memorabilia & Faithful Collectibles Finding genuine San Francisco 49ers autographs shouldn’t be a guessing game. At Autographed With Proof, we specialize in high-end Niners memorabilia sourced directly from the superstars. Whether you are looking for a signed Brock Purdy jersey or a limited edition autographed Christian McCaffrey football, our collection is curated for loyal fans and serious investors who demand absolute certainty. Why Collectors Trust Our 49ers Signatures The sports memorabilia market is unfortunately saturated with "pre-printed" signatures and forgeries. We separate ourselves by providing exact proof for our inventory. Every item in our San Francisco 49ers collection is backed by industry-leading authentication from Beckett (BAS), JSA, or PSA/DNA. In-Person Signings: We attend 49ers games at Levi's Stadium, training camp in Santa Clara, and private signings to ensure every pen stroke is legitimate. Photo & Video Proof: Most of our items feature "proof" photos of the 49ers player actually signing the specific item you are purchasing. 2026 Season Roster: We carry authentic signatures from the 2026 squad, including elite new arrival Mike Evans and returning defensive leader Dre Greenlaw. Beckett Authentication: We prioritize Beckett authentication, the industry gold standard, but we also offer items authenticated by PSA/DNA and JSA. Build Your San Francisco 49ers Investment Portfolio From legendary "Dynasty" icons like Joe Montana and Jerry Rice to modern-day powerhouses like Nick Bosa and Fred Warner, our inventory spans the greatest eras of 49ers history. We understand that a signed 49ers helmet or autographed equipment isn’t just a decoration—it’s a piece of team history. By combining rare items with airtight provenance, we help you build a collection that holds its value for years to come.
