A PSA 10 is not a card with no flaws. It is a card whose flaws nobody could find.
That distinction is the whole grade. Under enough magnification every card ever printed has something on it. Gem Mint means a grader looked, with tools, and did not find anything that crosses their threshold for that issue.
This page shows what that looks like. I own one PSA 10, bought to study for the grading estimator project, and the photographs below are that card.
What the grade requires
The full checklist lives on the PSA 10 requirements page, and the short version is four categories with nothing findable in any of them: centering, corners, edges, surface.
Worth repeating the part most guides bury: PSA publishes no numeric tolerance for any of those categories. The commonly quoted 55/45 front centering figure is hobby consensus, not a published standard, as I found when I went looking for the whitening number and came up empty for centering too.
What PSA does publish is that eye appeal and market expectation move grades:
The graders reserve the right, based on the strength or weakness of the eye appeal, to make a judgment call on the grade of a particular card.
What actually stops a 10
In rough order of how often each one costs somebody the grade.
Centering. The most common single reason, and the only one you can check yourself before spending money. Measure it. A card that misses on centering misses in the pack and nothing you do afterwards helps.
Corner softness under magnification. Not visible damage. The tip of one corner very slightly less crisp than the other three. This is the classic 10-to-9 defect.
Print lines and manufacturing marks. Baked in at the factory, entirely not your fault, counted anyway. This is the one that produces the most anger, because there was never a version of that card that could have graded higher.
Holo scratching. Foil marks from a sleeve, a finger, or the pack itself.
The uncomfortable maths
The reason "what does a PSA 10 look like" is such a common search is that people are trying to predict an outcome before paying for it.
At $79.99 for PSA's Regular service with a 40 to 50 business day turnaround, that instinct is correct. But the honest framing is this: assume your card is a 9 and see if the maths still works. Most cards that look like 10s to their owners are 9s. If a 9 loses you money, you are not making a grading decision, you are buying a lottery ticket with a two month delivery time.
Where this page is incomplete
I have one PSA 10. One card is an anecdote, not a sample, and it is a single set from a single era.
A 10 from a 1999 print run and a 10 from last year's set are held to different bars, because PSA judges against what the market expects for that particular issue. So the card below shows you what one Gem Mint card looks like. It does not show you the boundary, and the boundary is what you actually want.
If you own graded cards and would be willing to photograph them for this, I would genuinely like to hear from you.
