Grading math for this card
Prefilled with the latest qualifying sale for each grade where one exists. Replace any value with your own. We never suggest what grade your copy will get.
Compare grading math across cards · Formula from Grading: condition, uncertainty, and economics: grading pays only if your honest chance of the high grade exceeds (raw net + cost − other-outcome net) ÷ (high-grade net − other-outcome net). The 13% fee is an editable assumption, not a quoted tariff.
About Michael Gambon Autograph
Michael Gambon Autograph is a NNO Artbox Goblet of Fire Update Edition autograph card for Gambon as Albus Dumbledore. Collectors search for it because it pairs a major Harry Potter character actor with a signed Artbox movie-card insert and appears in graded examples with separate card and autograph grades.
Why this card matters
Verified factThe 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. [1]
Identifying the exact version
Verified factThe 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. [1]
What moves the price between versions and grades
AnalysisFor 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. [1]
Authenticity checks
AnalysisCompare 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.
Telling the versions apart
| Version | How to identify it |
|---|---|
| On-card autograph | NNO Artbox Goblet of Fire Update Edition autograph card signed by Michael Gambon as Albus Dumbledore; keep separate from prop, costume and other Gambon issues. |
| PSA/DNA slabbed | A slabbed example should show the Artbox Goblet of Fire Update identity plus separate card grade and autograph grade on the PSA label. |
