How to Read a Pop Report (and What the Numbers Actually Mean)
Updated Wednesday, September 16, 2026 · by the CardsNearby team
A population report ('pop report') is a grading company's public census: how many copies of a card it has graded, broken out by grade. It's the closest thing the hobby has to a supply-side ledger — and reading it well is the difference between paying for real scarcity and paying for a story.
Every major grader publishes one: PSA and SGC pop reports are searchable on their sites, CGC publishes a census, and Beckett exposes population data per card. All are free.
The three numbers that matter
For any card and grade, a pop report answers three questions:
- Pop at grade — how many copies exist in the grade you're buying (e.g., 'pop 61 in PSA 10').
- Pop higher — how many copies exist above that grade. A PSA 9 with zero 10s is a different asset than a 9 under ten thousand 10s.
- Total graded — how many copies have been graded at all, which proxies how heavily the card is submitted.
Gem rate: the ratio that prices modern cards
Gem rate = copies in the top grade ÷ total graded. A card with 5,000 PSA 10s out of 10,000 graded (50% gem rate) is easy to gem — the 10 carries a modest premium. A card with 200 tens out of 10,000 (2%) is condition-scarce, and the 10 can price at many multiples of the 9.
Worked example: suppose a modern rookie has 12,000 total graded, 1,800 in PSA 10, 7,000 in PSA 9. Gem rate is 15%. If raw copies run $40 and the grading all-in is $25, a $150 PSA 10 comp means your expected value per submission is roughly (0.15 × $150) + (0.60 × $60 for the 9) − $65 cost ≈ −$6. The pop report just told you not to grade it.
Reading pop across graders
Populations don't transfer between companies — a card can be pop 50 at PSA and pop 3 at SGC without the SGC copy being rarer in any meaningful sense. Compare within one company's census, and remember crossovers (cards regraded at another company) inflate totals: the same physical card can appear in two censuses.
Pop report red flags
Low pop is necessary for scarcity value but nowhere near sufficient. Watch for:
- Low pop because nobody submits it — a $3 card is pop 2 because grading costs more than the card, not because it's rare.
- Growing pop on 'rare' modern cards — pop reports are snapshots; heavy submission volume erodes scarcity premiums over months.
- Half-grade and qualifier rows (PSA's qualifiers, Beckett's subgrades) that fragment the census and make totals look smaller than they are.
Good to know
FAQ
Where do I find pop reports?
PSA (psacard.com/pop), SGC's pop report search, CGC's cards census, and Beckett's BGS population data — all free on each grader's site.
What is a good gem rate?
There's no universal 'good' — a low gem rate (under ~20%) makes top grades scarce and valuable but your submission risky; a high gem rate (50%+) makes tens cheap to make and cheap to buy. Price the grade spread against the rate.
Does a low population always mean a card is valuable?
No. Pop only measures graded copies. Cheap or unpopular cards have tiny pops because nobody pays to grade them — scarcity without demand is just a small number.
Do pop reports change?
Constantly — they're live censuses that grow with every submission. A pop-10 card today can be pop-300 next year; scarcity-priced modern cards are exposed to exactly that risk.
