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 Dumbledore's Office
Dumbledore's Office is a 2002 Wizards of the Coast Harry Potter TCG Chamber of Secrets location card numbered 15/140. Collectors search for it because the same card number exists as both a normal rare and a foil premium version, which must be kept separate.
Why this card matters
Verified factDumbledore's Office sits in the first rare block of Chamber of Secrets, a 140-card Wizards of the Coast expansion released for the Harry Potter TCG in October 2002. Pojo's set checklist lists card 15 twice, once as Foil Premium and once as Rare, which makes finish the core identity issue for this card. The card also represents a named location rather than a character, so its demand should be researched against exact card and finish rather than broad Dumbledore character searches. [1][3]
Identifying the exact version
Verified factStart with the English title, the Chamber of Secrets set, and card number 15/140. The non-holo version is the ordinary Rare entry, while the premium version is identified as Foil Premium in the checklist. Do not treat a foil listing, a non-foil listing, and a generic 'Dumbledore' listing as the same object. If a seller uses only marketplace wording, confirm the front photo, back photo, card number, and reflective treatment before using the listing as a comp. [1][2]
What moves the price between versions and grades
AnalysisThe most important separation is finish: the foil premium and the non-holo rare are different comparables. Condition also matters because early-2000s WotC foils can show scratches, edge whitening, or surface wear that is not visible in a single straight-on photo. A graded comp should only be compared with the same grader and grade. A raw 'near mint' listing is not equivalent to a PSA 9 or PSA 10 unless the card has actually been graded. [4][5]
Authenticity checks
AnalysisCompare the card against checklist references and clear photos of the correct Chamber of Secrets version, checking the title, 15/140 number, set identity, back design, finish, card size, borders, text, and surface. Use several checks together and avoid destructive tests. For slabs, match the label, card number, grader, cert, and visible card to the certification page, but remember that copied certification numbers exist, so a valid lookup alone does not authenticate the physical item.

Telling the versions apart
| Version | How to identify it |
|---|---|
| Unlimited non-holo rare | English Chamber of Secrets card numbered 15/140 with the normal rare treatment and no foil premium surface. |
| Unlimited foil premium | English Chamber of Secrets card numbered 15/140 with Foil Premium treatment; do not merge with the non-holo rare. |
