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 Philosopher's Stone
Philosopher's Stone 21/80 is a Transfiguration Rare item card from Wizards of the Coast's 2002 Adventures at Hogwarts set. Collectors search for it because the object is central to the first Harry Potter story and because foil premium and normal rare copies are distinct variants.
Why this card matters
Verified factPhilosopher's Stone is an Item card from Adventures at Hogwarts, listed as AAH 21/80 with Transfiguration Rare identity in the opened reference. The card depicts a central story object rather than a character portrait, so its collectible appeal is tied to story significance and set completion. The opened reference records both English foil premium and English normal rare printings, which are separate targets for a collector building the set. [1]
Identifying the exact version
Verified factThe identity check should start with AAH 21/80, the Philosopher's Stone name, Item type, and English language. The opened reference lists English, French, German, and Italian printings, with foil premium and normal rare variants. Marketplace pages that omit finish or use generic Harry Potter wording are not enough for pricing. A buyer should confirm the card number and whether the surface is foil premium or normal before comparing it to any sale. [1]
What moves the price between versions and grades
AnalysisNo opened dated completed sale for this exact card met the batch standard in this pass. Search results and active marketplace pages suggested that copies exist for sale, but those are not sale records without an opened completed-sale page showing date and price. Future comps should separate English foil premium, English normal rare, non-English printings, raw condition, and slabbed grade before estimating a range. [1][4]
Authenticity checks
Verified factCompare the card against the opened reference for AAH 21/80, the Philosopher's Stone name, Item type, Transfiguration Rare identity, language, and finish. Use multiple checks: front and back images, corners, edges, surface, print quality, and seller history. Do not use destructive tests. For graded copies, cert verification is useful but not enough, because PSA states that genuine cert numbers can be copied onto counterfeit inserts. [1][2][3]
