In sports cards, Pop 1 is short for “population of 1”: only one copy of that card has received that grade from that grading company.
“Pop” comes from the population reports that grading companies publish. They count how many copies of each card they’ve graded, and at which grade. So a Pop 1 card is unique in one specific sense: it’s the only one in that condition as assessed by that grader.
Here’s a real example:
In the above picture showing pop counts for different Victor Wembanyama cards from 2023-24 Panini Prizm Basketball (this screenshot is from 2024, so some counts will have gone up since):
- The Black 1/1 in PSA 10 is Pop 1
- The Blue Prizm in PSA 9 is Pop 44
- The Blue Choice Prizm in PSA 6 is Pop 1
You’ll often see a pop count followed by how many copies exist in a better grade. For the Victor Wembanyama Blue Choice Prizm PSA 6 example, you would say “Pop 1, 17 higher.” “Pop 1, none higher” means it’s the only copy at the top grade.
Pop 1 vs. a 1/1 card: what’s the difference?
These get mixed up a lot, but they mean different things:
- A 1/1 (“one of one”) is a card the manufacturer only printed once. The serial number on the card says 1/1. Only one copy exists, period.
- Pop 1 is about grading, not printing. It means only one copy has received that grade from that grading company so far. Thousands of copies of the card might exist.
A graded 1/1 card will always be Pop 1, as with the Black 1/1 PSA 10 above. But most Pop 1 cards are not 1/1s.
Does Pop 1 make a card more valuable?
It depends on the grade. A Pop 1 at the top grade, with nothing higher, can command a big premium because no better copy exists. A Pop 1 in a low grade, like the “Pop 1, 17 higher” PSA 6 above, usually doesn’t, because collectors can buy one of the 17 better copies instead. If you’re not sure what separates a PSA 6 from a 10, see the PSA grading scale.
Keep a few other things in mind:
- Populations change. Today’s Pop 1 can become Pop 3 as more copies are graded, especially for recent cards. Grading volumes hit record highs in 2025 and 2026, so modern pops are climbing fast.
- Each grading company counts separately. A card can be Pop 1 at PSA and have several copies graded by CGC, SGC or Beckett.
- Check the population report yourself. Don’t rely on a seller’s “Pop 1” claim without looking it up.
- Check the slab too. A high-value Pop 1 is exactly the kind of card counterfeiters target, and a fake slab can carry a real cert number. Here’s how to spot fake PSA slabs.
How to check a card’s pop
PSA’s Population Report is free on psacard.com (search for the set, then find the card). CGC and SGC publish their own population data too. Tools like GemRate combine pop counts across several graders, which is handy when a card has been graded by more than one company.
If you’re deciding whether to submit a card that could be a low-pop gem, run the numbers first with the card grading calculator.
FAQ
Is a Pop 1 PSA 10 worth more?
Usually, if people want the card. A Pop 1 PSA 10 with none higher is the best graded copy PSA has seen, and collectors chasing the top copy have only one to buy. Low pop doesn’t create demand on its own, though. A Pop 1 PSA 10 of a card nobody collects is still a card nobody collects.
What does Pop 2 mean on a card?
Pop 2 means two copies of that card have received that grade from that grading company. Pop 3 means three, and so on.
What is a good PSA pop?
There’s no magic number. What matters is the pop compared with demand, and the pop at your grade compared with the grades around it. A PSA 10 pop of 50 is tiny for a popular rookie card and huge for an obscure base card. A low PSA 10 pop next to a big PSA 9 pop is what drives the big price jump from 9 to 10.
Is PSA 1 or 10 better?
PSA 10 (Gem Mint) is the best grade. PSA 1 (Poor) is the lowest. Don’t confuse a PSA 1 with Pop 1: one is a grade, the other is a count of how many copies have that grade.
