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. ## Identifying the exact version Start 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. ## What moves the price between versions and grades The 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. ## Authenticity checks Compare 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. ## Common misconceptions - **Myth:** All Hermione, Potion Maker cards can be priced together. **What the evidence says:** Premium, non-premium, First Edition, Unlimited, raw, and graded copies need separate comp buckets. - **Myth:** Population equals how many copies Wizards printed. **What the evidence says:** Population is only a graded-count field from a grader or report; no exact print run was established. - **Myth:** A PSA 10 value can be estimated from raw listings if no PSA 10 sales exist. **What the evidence says:** The pricing chapter requires sold comps for the exact grader and grade; otherwise the value remains not established. - **Myth:** Pack fresh means it should grade high. **What the evidence says:** Grading depends on centering, corners, surface, edges, and defects; pack origin is not a grade guarantee. ## FAQ ### How much is Hermione, Potion Maker 29/140 worth?
