If you've spent any time in the graded card market, you've heard the term "pop report" thrown around. Understanding how to read and use a PSA (or CGC) population report is one of the most powerful skills a collector or investor can develop — it tells you exactly how scarce a graded card really is.
What Is a Population Report?
A population report (pop report) is a publicly accessible database maintained by grading companies that shows how many copies of a specific card have been graded at each grade level. PSA publishes its pop report at psacard.com/pop, and CGC maintains a similar registry at cgccomics.com.
For every card in their system, you can see:
- How many copies have been submitted for grading
- How many received each grade (1 through 10)
- The total "population" at PSA 10 (the top grade)
Why Does the Pop Report Matter?
Scarcity drives value. A card with only 12 PSA 10 copies in existence is worth significantly more than the same card with 4,000 PSA 10s — even if the raw card is identical. Pop reports give you a verifiable scarcity number to anchor pricing decisions.
How to Use Pop Reports When Buying
Low pop = premium pricing is justified. If a card has fewer than 50 PSA 10s, expect to pay a meaningful premium over the average sold price. These copies are genuinely rare and command collector premiums.
High pop = buyer's market. A card with 5,000+ PSA 10s is unlikely to appreciate significantly unless demand spikes dramatically. These are safer buys at lower prices but have a lower ceiling.
Watch for population growth. When new submissions arrive in bulk (often after a reprint or re-release), a previously low-pop card can suddenly have 10x more PSA 10s, which suppresses value. Keep an eye on pop count trends over time.
PSA 10 vs. PSA 9: Does the Gap Matter?
Always check the PSA 9 pop alongside the PSA 10. If there are 50 PSA 10s but 2,000 PSA 9s, the card is clearly difficult to grade at gem mint — which supports the PSA 10 premium. If both grades have similar populations, the gap between a 9 and 10 may be narrower than the price difference suggests.
