PSA/DNA slabbed is an authentication/holder state rather than a separate printing. ## Why this card matters The opened Heritage lot page identifies the item as a 2006 Artbox Harry Potter and the Goblet of Fire Update Edition Michael Gambon Autograph Card. The same lot description states that the card was signed by Michael Gambon from that trading-card set and that PSA graded the card Near Mint 7 with autograph Mint 9. This establishes a concrete graded sale record for a specific card, set and authentication format, rather than relying only on marketplace titles or general Harry Potter autograph demand. ## Identifying the exact version The identity should be recorded as Artbox, 2006, Goblet of Fire Update Edition, NNO autograph insert, Michael Gambon as Albus Dumbledore. Do not merge it with Gambon prop cards, costume cards, Order of the Phoenix Update replacement autographs, unsigned Dumbledore cards, or signed photos. For slabs, the card grade and autograph grade are separate fields. A record such as PSA 7 AUTO 9 means the card condition and the autograph assessment are not the same number. ## What moves the price between versions and grades For this card, the strongest comp filters are actor, exact Artbox set, autograph format, grader, card grade and autograph grade. A PSA 7 AUTO 9 sale should not be averaged with raw copies, a PSA 8 Auto 10, or another Michael Gambon autograph from a different Artbox release. The Heritage sale recorded here is one qualifying public auction result. It is useful evidence, but a single sale is not enough to define a broad market range without additional matching comps. ## Authenticity checks Compare against official references; multiple checks; no destructive tests; copied cert numbers exist. For this card, match the Goblet of Fire Update identity, Michael Gambon signer, Albus Dumbledore role, card design and PSA/DNA label details against the seller's exact photos. Confirm the cert, but also inspect holder, label, surface, corners and signature placement. Autograph grade, card grade and authentication result should be recorded separately so a strong autograph grade does not hide card-condition issues. ## Common misconceptions - **Myth:** Albus Dumbledore is a separate variant from the Michael Gambon autograph. **What the evidence says:** The opened Heritage lot identifies Michael Gambon as the signer and Dumbledore as the portrayed role; no separate Dumbledore variant was established. - **Myth:** The autograph grade and card grade are the same thing. **What the evidence says:** The Heritage lot reports PSA 7 AUTO 9, showing separate card and autograph assessments. Chapter 09 also says autograph and card grade are separate fields. - **Myth:** One Heritage sale proves a standing value for every copy. **What the evidence says:** Chapter 03 treats one sale as evidence for that exact comparable, not a guaranteed price for other grades or formats. ## FAQ ### How much did a PSA 7 AUTO 9 Michael Gambon Goblet of Fire Update autograph sell for?
