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 Troll in the Bathroom
Troll in the Bathroom is a rare Adventure card from the 2001 Wizards of the Coast Harry Potter TCG Base Set. Collectors search for it because it is an early WotC Harry Potter card tied to a recognizable Sorcerer's Stone scene and because foil premium and edition variants should not be merged.
Why this card matters
Verified factTroll in the Bathroom sits in the first Harry Potter TCG release from Wizards of the Coast, a 116-card Base Set checklist. The card is number 19/116, has Adventure type text, and is credited to illustrator Michael Koelsch. Its collector interest is mostly identity-driven: early WotC issue, recognizable scene, and a premium foil version that can be confused with the ordinary rare if listings are searched only by title. The evidence supports the checklist identity, not any exact print run or surviving-copy count. [1]
Identifying the exact version
AnalysisStart with the card number 19/116 and the Base Set name, then separate finish and printing. A non-premium copy should not be priced as a foil premium copy, and a First Edition copy should not be merged with Unlimited. The safest listing title includes name, set, number, language, finish, printing, and raw condition or slab grade. If a seller only says 'Troll in the Bathroom holo' or 'rare Harry Potter card,' the exact variant is not established until photos show the front, back, finish, and any edition stamp. [1]
What moves the price between versions and grades
AnalysisThe major comparison problems are finish, edition, and condition. A foil premium copy, a non-premium rare, a First Edition copy, an Unlimited copy, a raw card, and a PSA slab are separate markets. The knowledge-base pricing rule applies especially here because public sold evidence for this exact card is thin: do not fill a missing PSA 10 comp with a raw sale, an asking price, or a different WotC Harry Potter rare. Centering, corners, surface wear, and foil scratching can all matter if the card is graded. [1][2]
Authenticity checks
Verified factCompare the card against the checklist identity and a known authentic example: Base Set, 19/116, Adventure type, Michael Koelsch credit, correct back, size, text, and finish for the claimed variant. Use several checks together; do not use destructive tests. For slabs, verify the cert but also compare holder, label, and card photos, because PSA says public certification numbers can be copied onto counterfeit inserts. For raw foil copies, request angled-light photos to evaluate foil surface, scratches, dents, edge wear, and any alteration signs. [1][2][3]
