# Cooper Flagg Debut Patch Auto: The 1/1 Explained > The Cooper Flagg rookie debut patch autograph 1/1 from 2025-26 Topps Chrome Updates Basketball — what it is, the offers on the table, and how it compares. Category: NBA On Monday evening, August 10, 2026, Jason Williams — a machine shop owner from Clover, South Carolina — paid $515 for a Dallas Mavericks team spot in a live YouTube break and ended up pulling the 2025-26 Topps Chrome Updates Basketball #DPA-CF Cooper Flagg Rookie Debut Patch Autograph, serial 1/1: the first basketball card ever produced in the RDPA format. Topps confirmed on X the next morning: "history was made in rhode island." Here is exactly what the card is, who wants it, and what the comps actually say. ## What exactly is a Debut Patch Autograph? The RDPA format launched in 2023 Topps Chrome Update Baseball. The 2025-26 Topps Chrome Updates Basketball is the first basketball edition — so Flagg's card is the format's debut in an entirely new sport. Every detail on it is literal. The patch comes from the jersey Flagg wore during his NBA debut on October 22, 2025 (10 pts, 10 reb vs. San Antonio Spurs) — physically removed, authenticated, and sent to Topps. The autograph is hard-signed on-card — not a sticker — signed at Fanatics Fest NYC on July 17, 2026; Mike Mahan, CEO of Fanatics Collectibles, called it "definitely the most important thing we've had signed at Fanatics Fest." ## What are the offers on the table? Three serious parties have come forward — none has closed a sale. Williams told CNN he's in no rush: "I'm not even looking at the money." - Goldin Auctions: $1.5M cash advance against auction consignment; Goldin's stated auction target is $3M–$5M. - Alt marketplace: $3.6M leading bid in a live Debut Bounty Auction — binding only if Williams consigns to Alt, with 15 days remaining as of reporting post-August 10. - Dallas Mavericks (non-cash): 2 premium lower-level season tickets for 32 years, a signed game-worn Flagg rookie jersey, a postgame photo opportunity, a private shoot with the ROY trophy, and an expenses-paid road trip to Mavs vs. Celtics. ## How does it compare? The Skenes and Kurtz precedents Baseball's RDPA 1/1s are the only direct comps for this format.
