Card Errors and Variations: How to Spot Them
Some cards are worth more because of how they were printed rather than who is on them: a mistake that got fixed partway through, a photo swapped for a short run, a first print that looks slightly different from every later one. Knowing the difference is worth real money — a 1990 Pro Set Fred Marion sells for $1.50 or $58.40 depending on one detail in the photo. This guide covers the kinds you will run into, which ones actually move a price, and how to check a card yourself before you buy, sell or grade it.

Error, variation or misprint?
- Error — a mistake in what was printed: the wrong photo, a misspelled name, someone else’s statistics, a missing name or symbol.
- Variation — two or more versions of the same card. Some come from a fixed error; others are planned, like a short-printed photo.
- Misprint — a problem with how a card was printed: off-centre, an ink smear, a blurry image, a crooked border. These are flaws, not versions, and they usually lower a card’s value rather than raise it.
Corrected or never corrected — the question that decides the price
An error only creates a second version if the card company fixed it during printing. If it was fixed early, the error is the scarce one. If it was fixed late, the corrected card can be the scarce one. If it was never fixed, every copy has it — it is simply the card.
The 1988-89 O-Pee-Chee Kevin Lowe, which shows Wayne Gretzky’s statistics and was never corrected, sells for $1.13 against $0.99 for a copy listed without the error named — no real premium at all. Compare that with the Fred Marion above, corrected by airbrushing: nearly forty times the price.
The kinds worth knowing, with examples
- Cover-ups. Something on the card had to be hidden, and the company tried several ways. The 1989 Fleer Randy Johnson Marlboro billboard and the 1989 Fleer Billy Ripken bat knob are the famous ones — see baseball error cards.
- Missing ink, stamp or symbol. A layer of printing that should be there is not. The 1990 Topps Frank Thomas with no name on the front is the big one: PSA has graded just one a 10. In Pokémon, every Unlimited Jungle holo also exists without its set symbol, and a Base Set Pikachu exists with the “1st” and the “d” missing from its 1st Edition stamp — see Pokémon errors and variants.
- Wrong photo or wrong back. A different player pictured where the named one should be. The 1990-91 SkyBox Dyron Nix with Wayman Tisdale on the back sells for $8.41 against $1.13 — see basketball error cards.
- Wrong text or statistics. Often worth little: small print is not what buyers pay for — see the Montana example in football error cards.
- Print runs. Not a mistake, but the biggest money of all in Pokémon: a 1st Edition Base Set Charizard sells for $9,541.19 ungraded, an Unlimited one for $359.75. Same card, different run.
- Same card, different printer. The 1979-80 Gretzky rookie was printed by both O-Pee-Chee and Topps, and graded copies of the O-Pee-Chee sell for far more — see hockey error cards.
- Short prints and photo variations. Planned, not mistakes. Topps flagship baseball, for example, prints some cards with a different photo in smaller numbers. You can confirm one without guessing: the last three digits of the code printed on the back mark it. For 2022 Topps, a code ending in 560 is a short print and 561 a super short print; other years use other endings, so check a guide for your year. More in short print and photo variation.
- Test prints. Cards made before a set was final. The best-known sold for $360,000 at Heritage Auctions on January 14, 2021: a Blastoise test print from 1998, graded CGC 8.5, one of four CGC has certified and the only one with a blank back.
How to check a card yourself
- Find the exact checklist entry. Look the set and card number up in a checklist that lists errors and variations. If your version is not on it, it is probably a one-off flaw, not a recognised version.
- Point at the difference. Put your card next to a photo of each version. If you cannot point to the difference, a buyer will not pay for it.
- Price the version, not the card. Price guides often list versions separately — and sometimes lump them together, so the headline price is the common one.
- Read the sale, not the title. Sellers mislabel versions all the time. Look at the photo in every sale you use.
- Count the sales. A price built on a handful of sales can swing hard. Say how many there were when you quote it.
Fakes and altered cards
The more a version is worth, the more reason someone has to fake it or to “improve” a real card. PSA will authenticate a card that has been trimmed, recoloured, restored or cleaned but will not give it a number grade; it labels it “Authentic Altered”, and has not said which alteration since 2010. Among the ungraded Gretzky rookies sold in September 2026 were one listed as trimmed and one listed as PSA altered.
- Compare the size, edges and corners with a known-genuine copy. A trimmed card can come out slightly smaller or uneven.
- For an error that is only a few words or a patch of colour, be wary of an ungraded copy at a high price, and have the version confirmed by a grading company before you pay a premium for it.
- Above a few hundred dollars, buy it already graded by a major grading company.
