In short: A factory error happened on the press, the foiler or the cutter, and the ones that pay are the ones collectors have already catalogued and can search for by name. A print flaw is also from the factory but is too common to track, and damage happened after the pack was opened. Price any error by comparing sold listings of that error against sold listings of an ordinary copy of the same card. A factory crimp still grades as a crease, so plenty of real errors do better raw than slabbed.
Three groups, and only one of them pays
Hold the card flat under a lamp and look at whatever made you stop. A stripe of the next card along the bottom edge. A line pressed through the artwork. A holo pattern that quits halfway across the window. Before money, origin: every odd Pokémon card belongs to one of three groups, and the group decides everything that follows.
A factory error was made on the press, at the foiling stage or at the cutter, before the card ever reached a pack. A print flaw also came from the factory, but happens often enough that nobody bothers to name it. Damage arrived later, after someone opened the pack. Only the first group has a market of its own. The other two show up in the grade instead, as surface or as wear.
Ask whether a person could have done it
Ask one question about the mark. Could a person have done this after the pack was opened? A crease could. A missing holo layer could not. That test sorts most cards in about five seconds, and the table sorts the rest by category.
Two rows sit on the fence. Holo bleed leaves the factory like any other error, but it turns up so often in some sets that the market reads it as normal printing, which is what lands it in the print flaw row. A crimp goes the other way, catalogued as an error and scored as a crease. The rows that pay are the ones a buyer can type into a search box.
| What you see | Error, print flaw or damage | How the market treats it |
|---|---|---|
| Miscut, part of the next card showing | Error, at the cutter | Sells as an error when the cut is dramatic and the card is wanted |
| Crimp, a straight line pressed across the card | Error, at the pack sealer | Catalogued as an error, and graded as a creased card |
| Ink error, wrong, missing or doubled ink | Error, at the press | Priced on its own when the run is known and repeatable |
| Missing or misaligned holo layer | Error, at the foiling stage | Collected as an error, strongest on cards whose holo is the point |
| Wrong back, another set or another game | Error, wrong stock loaded | Scarce and actively hunted, and checked hard by buyers |
| Text or symbol error, wrong name, number or set symbol | Error, at the plate | The catalogued ones have followings; the rest have none |
| Holo bleed, foil spilling past the art window | Print flaw, at the foiling stage | Routine in some sets, so it usually prices as a normal copy |
| Uneven borders with all four still on your card | Print flaw, at the cutter | Read as centering and scored in the grade, never listed as an error |
| Crease, bend, scuff or a whitened edge | Damage, after the pack | Prices as the condition it leaves, whatever the listing calls it |
Off-centering is scored in the grade
Centering is not an error. Cards are cut from large sheets and the cut wanders across the run, so borders are never exactly even. Graders measure that wander and fold it into the number. The further the borders fall from even, the lower the ceiling on the grade, with corners and surface unchanged. Centering is scored, not catalogued.
The border is the line. If all four borders still hold the card's own art and text, it is a grade question. Once the cut runs far enough that part of the neighboring card sits on yours, it is a miscut, and miscuts are collected.
Sellers often list a mildly off-center card as an error because the word moves listings. Buyers who collect miscuts are not fooled, and the card prices as its grade.
Find out whether your error has a name
What separates an error with a market from one without is a name. Some 1st Edition Jungle and Fossil cards left the factory with the set symbol missing, the same mistake repeated across a print job, and collectors have catalogued those prints by name ever since. A documented error has a search term, a rough sense of how many exist, and a run of sold listings behind it.
Test yours in the search box. Describe the mark the way a seller would, add the card name and set, and read the completed listings. If several sellers reach for the same words, no set symbol or miscut or crimped, the error is named and there are comps to price it against. If every listing describes the mark in its own way, or the only matches are ordinary copies of the card, nobody has named it yet.
A factory crimp is still a crease to a grader
A crimp is a straight line pressed across the card by the machine that seals booster packs. It happened at the factory, collectors know the term, and crimped cards trade. It is also, to a grader, a crease. Graders score the card in front of them, and a pressed line through the surface pulls the number down whether the sealer or a back pocket put it there.
That is why crimped and badly miscut cards mostly sell raw. A slab records a low grade next to an error the label does not explain, while a raw card with sharp photos of the crimp reaches the collectors who want exactly that. Damage is the simpler case. A bend, a scuff, a soft corner, an edge bleached by sunlight: none of it is an error, whatever the listing calls it.
Wrong backs are the other case worth naming. A Pokémon front on a back from a different set, or from another game entirely, is a genuine factory mistake and one of the few errors buyers hunt on sight. A back that matches no set at all is a different question, and the counterfeit checks settle that one before the error question is worth asking.
Price the error against a normal copy
Price the error against the normal copy of the same card, and use sold listings rather than asking prices. Search the card by name, set and collector number, filter to sold, and read the last ten sales of ordinary copies in the condition yours is in. Put those ten in order and take the middle. Then run the search again with the error term added, miscut or crimped or no set symbol, and take the middle of the last ten of those.
The gap between the two middles, in dollars, is what that error pays on that card this month. Two rules keep the number honest. Compare like with like, because a graded error and a raw error are separate markets, and a Near Mint copy is no comp for a creased one. And if the error search returns fewer than about five sales in the last few months, there is no market price yet, only the last figure somebody agreed to.
The same method works on a slab. Search the card with the error term and the grade together, read what those slabs did, then compare against slabs of the normal copy at the same grade. Fewer sales means a wider answer, so quote yourself a range instead of a number.
Demand for that exact error sets the price
An error's price is set by how many people collect that specific error, not by how strange the card looks. A missing-ink run that a few hundred collectors hunt has a market, a bid history and a floor under it. A smear nobody has named has one interested buyer at a time, and the next sale can land anywhere.
Age helps, because older errors have had twenty years to be catalogued, argued over and given a name that people search. Scarcity does not help by itself. Every misprint is scarce. That is what the word means, and most misprints are worth what the card underneath them is worth.
Get the error named on the slab label
CGC requires its Error designation on any card submitted with a printing error and charges no extra fee for it, which is the cleanest way to get the error named on the label instead of argued about in a listing. The tier is set by declared value and by speed. Economy is $20 a card, covers a declared value up to $1,000 and runs 90 working days. Standard is $55, covers up to $3,000 and runs 10 working days.
Turnaround is quoted in working days and is an estimate, not a guarantee. CGC may also move a card to a higher tier if it reads the fair market value as higher than the declared value.
PSA grades the card as it finds it. Standard is $59.99 per card, with a maximum insured value of $1,000 and an estimate of 90 to 100 business days. The card comes back sealed in a tamper-evident case with the grade and the cert number on the PSA LightHouse label, so a crimp reaches the next buyer as whatever number it earned.

Identify the base printing before you price the error
An error is priced against the normal copy of the same card, so the normal copy has to be pinned down first: set, collector number, rarity, finish and language. CardLens matches the exact printing from a photo and shows a value range built on recent eBay sales of that printing. The sales behind the range are visible in the app, so the ordinary side of the comparison is a set of real sales rather than a guess.
Photograph the card flat, with the light off to one side so a crimp or a missing holo layer reads in the frame. Then run the error search yourself and measure the gap.
Questions collectors ask
Are Pokémon card misprints worth anything?
Most are not. The test is whether the mark has a name. Search the card plus the words a seller would use for the mark, and see whether the same term comes back across several completed listings. A named error has collectors waiting for it. An unnamed one has whoever happens to be looking.
What are the most valuable Pokémon card errors?
The documented ones, meaning errors that ran across a print job, got catalogued and have a name collectors type into a search box. The 1st Edition Jungle and Fossil cards missing the set symbol are the standard example. Wrong backs sit in the same bracket, and buyers check both hard, so photograph the front and the back before you list.
Is an off-center card an error?
No. Centering is how far the cut wandered on the sheet, and every card wanders a little. Graders measure it and fold it into the grade. It becomes an error only when the cut runs far enough to put part of the next card on yours, which is a miscut.
How do I get an error card graded?
Declare the error on the submission form. CGC requires its Error designation on a card submitted with a printing error, so the mark is graded and named as an error rather than read as a damaged copy. It does not stop a crimp pulling the grade down. It stops the next buyer guessing where the line came from.
What is a crimped Pokémon card?
A card with a straight line pressed across it by the machine that seals booster packs. It is a factory error and collectors buy them. It is also a crease to a grader, so a crimped card grades low and usually trades raw with clear photos of the line.
