What does pop report mean?
A pop report is a census provided by grading companies that shows the total number of a specific card ever graded and the distribution of those grades to help collectors determine scarcity.
A Pop Report, short for population report, is a searchable database maintained by major third-party grading companies like PSA (Professional Sports Authenticator), BGS (Beckett Grading Services), and SGC (Sportscard Guaranty Corporation). These reports track every card authenticated and graded by the company, providing a breakdown of how many copies of a specific card exist at every numerical grade level.
How Collectors Use Pop Reports
Investors and collectors use these reports to determine relative scarcity. While a card might have a high total population, it may have a very low "Pop 1" or "Low Pop" count in a Gem Mint 10 grade.
- Identify Scarcity: A card like the 1986 Fleer Michael Jordan #57 has a total PSA population exceeding 25,000 copies, but fewer than 325 of those have earned a PSA 10 grade, driving its six-figure valuation.
- Market Timing: If a "Pop Report" shows a rapid increase in graded copies, it indicates higher supply entering the market, which can lead to price softening.
- Detecting Trimmed Cards: Sudden jumps in the population of high-grade vintage cards can alert the community to potential card doctoring or massive "re-submitting" (cracking a card out of its holder to try for a higher grade).
Key Terms in Pop Reports
- Pop 1: This means only one copy of that specific card exists in that specific grade worldwide for that grader.
- None Higher: This indicates that no copies of the card have been awarded a higher grade than the one currently being viewed.
- Total Pop: The cumulative sum of all graded iterations of that card, regardless of the numerical score.
For example, looking at the 2019 Panini Prizm Zion Williamson Base #248, the PSA Pop Report shows a staggering total population over 40,000, with over 18,000 PSA 10s. This high population explains why the card’s value is lower compared to rarer "Silver Prizm" parallels with lower population counts. Analysis of these reports is essential for calculating a card's Scarcity Multiplier, which is the price gap between a common grade (PSA 9) and a rare grade (PSA 10).
Related questions
Does a high pop report affect card value?
High population (high pop) indicates a large supply of a card in a specific grade, which typically decreases its market value compared to low-population alternatives.
How do I check a card's population?
Collectors check pop reports by entering the card's name or the specific certification number found on a slab into the PSA, BGS, or SGC online databases.
What does 'Pop 1' mean in card grading?
A 'Pop 1' card is the only specimen in existence to have received that specific grade from a particular grading company, making it extremely rare.
Are PSA pop reports 100% accurate?
Pop reports are generally accurate, but they can be inflated if collectors 'crack' cards out of slabs to regrade them without returning the original label to the company.
