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.
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 Hermione, Potion Maker
Hermione, Potion Maker is a rare Character card from the 2002 Wizards of the Coast Chamber of Secrets Harry Potter TCG set. Collectors search for it because it is a Hermione card from the final WotC Harry Potter expansion and because holo portrait premium and edition variants can be confused in listings.
Why this card matters
Verified factHermione, Potion Maker is listed as card 029/140 in the Chamber of Secrets set, with Character type text, Kim Graham illustration credit, and Rare rarity. The card's collector interest comes from the Hermione subject, the WotC Harry Potter era, and the Chamber of Secrets set identity. Its exact value cannot be inferred from the character name alone because finish, edition, language, raw condition, and slab grade all change the object being compared. The evidence here establishes identity, not print run. [1][2]
Identifying the exact version
Verified factStart with the Chamber of Secrets set and number 29/140. Then check whether the card is non-premium or holo portrait premium, and whether it is First Edition or Unlimited. The set list confirms Hermione, Potion Maker at number 029, and the individual card page confirms rare status and Kim Graham as illustrator. A listing title that says only 'Hermione holo' is not enough; photos must show finish, edition stamp, language, front, back, and condition before it can be assigned to a variant. [1][2]
What moves the price between versions and grades
AnalysisThe important pricing split is exact finish and printing first, then condition and grader. First Edition holo portrait premium, Unlimited holo portrait premium, non-premium rare, raw near mint, PSA 9, and PSA 10 are separate comparison groups. No acceptable opened sold-sale page was included for this exact card, so the honest price answer remains unknown. The correct next step is to open exact sold listings or auction results and exclude wrong finishes, wrong grades, lots, and other Hermione cards. [1][2]
Authenticity checks
Verified factCompare the card against the Chamber of Secrets checklist and a known authentic example: number 29/140, Hermione, Potion Maker name, Character type, Witch/Gryffindor/Unique classification, Kim Graham credit, and correct finish for the claimed variant. Use multiple checks together, including card stock, back design, print quality, foil or portrait treatment, size, corners, and edges. For slabs, verify the cert while remembering that PSA warns copied cert numbers exist. Do not rely on destructive tests or on one visual shortcut. [1][2][3][4]
