How to research a card before you buy it
A routine for any card purchase: pin down the exact printing, check sold prices, judge the copy from photos, read the grader's records and the seller's terms.

To research a card before you buy it, answer five questions in order and write each answer down: which exact printing it is, what that printing has sold for in the same condition or grade, whether this copy matches its description, what the grader’s records say if it is a slab, and what happens if it arrives wrong. The order matters. A price check means little until you know the printing, and a population count means little until you know the grade.
What should your research note hold?
Keep one note per card, on paper or your phone. It turns a listing into a set of facts you can check.
| Write down | Why it matters | Where to find it |
|---|---|---|
| Set, set code and card number | Two cards with the same name and art can be different cards | The card; Rip.fan’s set pages for English Pokémon |
| Finish and language | A holofoil, a first edition or a sports parallel can be priced apart from the base card | The card, and the printing named on a price page |
| Condition, or grader, grade and cert number | Condition and grade set the price | The listing photos and the slab’s label |
| Several matching sales, with dates | A sold price beats an asking price | Sold listings and sales-based market prices |
| Graded copies at that grade and the one below | Context for a slab’s grade | The grader’s population report |
| Seller, marketplace and deadline | What you can do if the card arrives wrong | The marketplace’s own policy pages |
Which printing is it?
Start with the card. Write down the card set, the card number, the finish and the language.
For English Pokémon cards, Rip.fan’s set pages give each set’s release date and series, and most also give its set code and how far its numbered set runs. A card numbered above that run, such as 161/131, is one of the cards numbered past the main set. Cards with their own price page name the rarity and, where known, the illustrator, and show prices printing by printing, so match the printing name to your card before you trust a figure. Our guides to reading a Pokémon card, rarity symbols and card finishes cover the details, and sports card parallels covers sports printings.
Language changes where a card sells. TCGplayer lists most non-English cards only as Listings with Photos, with Japanese Pokémon cards among the exceptions, and asks sellers to name the language in full in the title and description. Our guide to Japanese and English Pokémon cards explains the differences.
What has that printing sold for?
Use sold prices, not asking prices. TCGplayer warns that its Listed Median, the middle of current asking prices, can sit far from what buyers pay on older products with few copies for sale, while its Market Price is compiled from recent sales on its site. Gather several sales of the same printing in the same condition or grade, take the middle one and date it, as our guide on how to find what a card sold for explains.
For a raw English Pokémon card, the card price lookup shows a dated NM market price and the printing it is for, and each card’s own page has a low and a market figure for each raw condition where a price exists. If a price has just jumped or dropped, read it with our guide to card price changes before you act on it.
Does this copy match its description?
Look at the photos as if no label existed. eBay’s guidance asks sellers for clear images of the front, the back, any significant blemish and any grading label. If any of those is missing, ask for it.
Then check the corners, edges, surface and centering against what the listing claims. Our guide to card condition problems shows how each flaw moves a card down the scale, and the centering checker turns border widths into a split. Condition labels don’t mean the same thing on every marketplace, as our guide to buying raw cards online sets out.
The photos also become part of the deal. On TCGplayer, a Listing with Photos that arrives matching its photos, title and description doesn’t have to be taken back. Study them before you pay.
What do the grader’s records say?
For a slab, get the cert number and look it up on the grader’s own site. eBay asks sellers of graded cards to add the grader and the numerical grade, and recommends adding the cert number. CGC images every card after sealing it and shows those images in its Verify tool, so you can compare the centering and marks in CGC’s image with the seller’s photos.
Read the grade box too. On CGC’s scale, Authentic (AU) means a genuine card that got no number, and Authentic Altered (AA) means a genuine card that was altered. Our guide to spotting an altered card explains both, and spotting a fake slab covers the holder and label.
A population count only gives context. CGC’s report counts only cards CGC has graded, and its disclaimer says the counts are no guide to value or rarity and should not be relied on to make a purchase. Use it to see how many copies sit at your grade and the grade below, next to the sold prices for each. Our guide to reading a pop report walks through a row.
What happens if it arrives wrong?
Find out before you pay. On TCGplayer:
- Changing your mind does not qualify for a return or refund.
- Sellers take back singles only when the condition doesn’t match, the card is wrong (another set, printing or card), or a card is missing, and you have until 30 calendar days after the estimated delivery date to contact the seller.
- A card that changes in price after you buy it gets no refund, and the seller can’t ask for more.
- A suspected counterfeit can be reported within 30 calendar days of the estimated delivery date, and TCGplayer sends a prepaid label so its team can review the card.
Other marketplaces set their own rules. Our guides to buying raw cards online and buying graded cards online set out the windows at eBay and Whatnot.
Which stop signs should end the research?
| What you see | Why it matters | What to do |
|---|---|---|
| No photo of the back, or a stock image | You can’t judge the copy you would get | Ask for photos of that card |
| No set, number or printing in the listing | Your price check may be for a different card | Ask, or match them from the photos |
| A price far below recent matching sales | It may be another printing, a worse condition or a problem copy | Find out why before you pay |
| No cert record, or one for another card | The slab may not be what it claims | Don’t buy |
| AU or AA in a CGC grade box | No numeric grade, and AA means altered | Price AA against AA sales and AU against AU sales |
| No policy you can find for a wrong card | You may have no way to resolve a problem | Read the marketplace’s rules first |
What should you do once the card arrives?
Photograph the package and the card before you handle it, then check the card against your note: the printing, the condition, and the cert record for a slab. Report a problem inside the marketplace’s window. Keep the note afterwards with the price you paid and the date, because it doubles as a record for insuring a collection. For cards bought in person, our guide to your first card show covers the same checks at a table, and the glossary defines comps and a population report.
Frequently asked questions
What is the difference between a CGC Pristine 10 and a Gem Mint 10?
A Pristine 10 is flawless under 10-times magnification, with 50/50 centering, and gets its own Pristine 10 label. A Gem Mint 10 falls short on one criterion, with centering no worse than about 55/45 on the front and 75/25 on the back.
How does CGC grade an autograph?
On its own scale from 5 to 10, with no half grades. An autograph judged below 5 gets the Authentic designation instead of a number.
How do you find a CGC slab in CGC's pop report?
The CGC Cards Population Report runs by game, era and set for card games, and by sport, date range and set for sports cards. A link below the card images in CGC's Verify tool jumps straight to a slab's row.
