The PSA Pop Report is a free, publicly accessible database that tells you exactly how many copies of a given card PSA has graded and at what grade levels. To find undervalued cards, you look for low population counts at high grades — a card with only a handful of PSA 10s relative to the total number graded signals genuine scarcity, which the market may not have priced in yet. For example, a Base Set Alakazam that has thousands of PSA 9s but fewer than a hundred PSA 10s suggests the jump from 9 to 10 carries real rarity, and if the PSA 10 price hasn’t separated dramatically from the PSA 9, you may be looking at an undervalued card.
But the Pop Report is not a simple cheat code. It requires context — understanding submission trends, the difference between absolute and relative scarcity, and the quirks of how PSA categorizes sets. This article walks through how to actually read the Pop Report, what the numbers mean for card valuation, where the tool falls short, and how to pair it with market data to make smarter buying decisions. Whether you are hunting for long-term holds or looking for quick flips, the Pop Report is one of the most underused research tools in the hobby.

What Is the PSA Pop Report and How Does It Help You Find Undervalued Cards?
The psa Population Report is a running tally of every card PSA has ever graded, organized by set and card number. For each card, it shows the total number graded and breaks that total down by grade — from Authentic (no numerical grade) all the way up to Gem Mint 10. You can access it directly through PSA’s website at no cost. The data updates as new submissions are processed, though there can be a lag between when a card is graded and when it appears in the report. The connection to undervalued cards is straightforward: price should, in theory, reflect scarcity, but it often doesn’t. The Pop Report gives you hard data on supply at each grade level.
If a card has a population of 15 in PSA 10 and the last sale was comparable to cards with populations of 500, the market may not be accounting for how rare that gem mint copy actually is. Conversely, if a card you thought was scarce in high grade actually has a population of 2,000 in PSA 10, the current asking price might be inflated. The report turns guesswork about rarity into something measurable. It helps to think of the Pop Report as one leg of a three-legged stool. The other two legs are demand (how badly collectors actually want the card) and market pricing (what people are paying right now). A low pop count means nothing if nobody wants the card, and a high pop count doesn’t automatically kill value if demand outstrips supply. But when you find a card where the pop data and the pricing data are misaligned, that gap is your opportunity.
Reading the Numbers — What Low and High Populations Actually Mean
When you pull up a card on the Pop Report, you’ll see a row of numbers corresponding to each grade. The most important figures for value hunters are the PSA 10 and PSA 9 columns, since those are the grades that command meaningful premiums. A useful metric is the PSA 10 rate — the percentage of total submissions that earned a 10. If a card has been submitted 5,000 times and only 50 copies came back as a 10, that one percent gem rate tells you something important about the difficulty of achieving top grade for that particular card. However, raw population numbers can be misleading if you don’t account for context. A PSA 10 population of 20 sounds incredibly scarce, but if only 40 total copies have been submitted, the gem rate is actually 50 percent — meaning the card is easy to grade well, and more PSA 10s will flood in as submissions increase.
this is a common trap with newer sets or cards that haven’t been heavily submitted yet. The population is low not because the card is hard to grade, but because people haven’t bothered sending it in. If a card is inexpensive and the set is recent, expect the pop to climb. The cards where low population genuinely signals value tend to be older. Vintage cards from the Base Set, Jungle, Fossil, and Team Rocket era have been submitted in enormous quantities over the past two decades. If a card from one of those sets still has a tiny PSA 10 population after tens of thousands of total submissions, that scarcity is likely structural — the card is just hard to find in perfect condition. That is meaningful, durable scarcity, and it’s the kind the market tends to undervalue.
Why Certain Cards Stay Undervalued Despite Low Pop Counts
One of the most instructive examples in the Pokemon hobby is the non-holo rare from early sets. Take a card like Base Set Hitmonchan non-holo. It is not a chase card. Nobody is building a display around it. But if you check the Pop Report and find that the PSA 10 population is extremely thin relative to total submissions, you have a card where actual scarcity exists but collector demand hasn’t caught up. These cards tend to sit at modest prices for years before the market notices. The reason is that most buyers search by card name and set, glance at the grade, and buy based on recent comparable sales.
They are not cross-referencing the Pop Report. Sophisticated collectors and investors do check populations, but they represent a fraction of the market. The average buyer on eBay is not running population analytics before placing a bid. This information asymmetry is exactly why the Pop Report creates opportunities — the data is free and public, but most people do not use it. The flip side is that some cards have low pop counts and still aren’t worth chasing. If a card has zero cultural relevance, no competitive play history, and features a forgettable Pokemon, scarcity alone won’t drive meaningful appreciation. A PSA 10 of an obscure common from a mid-era set might have a population of 5, but if there are only 8 total submissions, it just means nobody cares enough to grade it. Scarcity is a necessary but not sufficient condition for value.
How to Cross-Reference Pop Data with Market Prices for Smarter Buys
The practical workflow looks like this: identify a card you’re interested in, pull its Pop Report data, then compare the PSA 10 population against recent sold listings on platforms like eBay. You’re looking for a gap — cases where the price doesn’t reflect the scarcity. A card with a PSA 10 pop under 100 that’s selling for the same price as cards with populations in the thousands is potentially mispriced. There is a tradeoff between precision and effort here. You can go deep, building spreadsheets that track pop-to-price ratios across entire sets, or you can do quick spot checks on cards you’re already considering buying. The deep approach is better for finding truly hidden gems — cards you wouldn’t have looked at otherwise — but it’s time-intensive.
The spot-check method is faster and works well if you already have a sense of which sets and cards tend to be undervalued. For most collectors, starting with spot checks and graduating to set-wide analysis as you get comfortable with the data is the practical path. One critical comparison to make is PSA 10 price versus PSA 9 price. If a card has a PSA 10 population of 30 and a PSA 9 population of 400, but the PSA 10 is only selling for 20 percent more than the PSA 9, that price gap is probably too small given the scarcity difference. Over time, as more collectors recognize the population disparity, the PSA 10 premium tends to expand. Buying into that gap before it widens is one of the more reliable strategies in card investing.
Common Pitfalls and Limitations of the PSA Pop Report
The biggest limitation is that the Pop Report only tracks PSA-graded cards. It tells you nothing about the raw supply sitting in binders, shoeboxes, and ungraded inventories around the world. A card might have a PSA 10 population of 10, but if thousands of near-mint raw copies exist and people just haven’t submitted them yet, the scarcity is illusory. This is particularly relevant during grading surges — when PSA turnaround times drop or prices decrease, submission volume spikes, and populations can shift dramatically in a short period. Another pitfall is resubmissions, sometimes called “pop pollution.” When a collector gets a PSA 9, cracks it out of the case, and resubmits hoping for a 10, the Pop Report counts both the original 9 and any subsequent grades. This means the total graded number is inflated relative to the actual number of unique physical cards. PSA has acknowledged this issue but hasn’t implemented a reliable way to deduplicate the data.
For high-value cards where the difference between a 9 and 10 is hundreds or thousands of dollars, resubmission rates can be significant. The pop counts for those top grades are less precise than they appear. You should also be cautious about treating the Pop Report as a static snapshot. Populations change constantly. A card you identify as undervalued today based on a low PSA 10 count could see a batch of new 10s added next month if a large submission lot comes through. Vintage cards are somewhat insulated from this — the supply of ungraded mint copies is largely exhausted — but modern cards are not. If you’re making decisions based on pop data for sets released in the last few years, treat the numbers as a floor, not a ceiling.
Using the Pop Report for Set-Wide Analysis to Spot Overlooked Cards
Instead of checking individual cards, some collectors pull the full Pop Report data for an entire set and sort by PSA 10 gem rate. This reveals which cards in a set are structurally harder to grade, regardless of whether the market has noticed. For instance, within a single vintage set, one card might have a gem rate of 2 percent while another sits at 15 percent. If both cards feature popular Pokemon and are priced similarly in PSA 10, the 2 percent gem rate card is arguably the better buy because its scarcity is harder to disrupt.
This set-wide approach also helps you identify cards affected by known print quality issues. Certain cards from certain print runs are notorious for centering problems, surface issues, or edge wear straight out of the pack. The Pop Report reflects this in the numbers — these cards will show heavy clustering in the PSA 7 to 8 range with a steep dropoff at 9 and 10. That pattern is worth paying attention to, because print-quality-driven scarcity is permanent. No amount of future submissions will fix a card that was poorly cut at the factory.
The Future of Pop Data and What It Means for Collectors
As the grading industry evolves, population data is becoming more accessible and more granular. PSA has made improvements to their Pop Report interface over time, and third-party tools have emerged that aggregate pop data with pricing information, making the kind of cross-referencing described above much faster. This trend is likely to continue, which means the informational edge from using pop data will shrink as more collectors adopt these tools.
That said, the fundamental principle will remain: the market is slow to price in scarcity data, especially for mid-tier and lower-tier cards that don’t attract heavy speculation. Even if more people start using the Pop Report, the collectors who combine pop analysis with genuine knowledge of card history, print runs, and cultural significance will continue to find gaps. The Pop Report is a tool, not a strategy. The strategy is in knowing which low-population cards actually matter — and that requires the kind of judgment no database can automate.
Conclusion
The PSA Pop Report gives you a concrete way to measure card scarcity at each grade level, and the most actionable insight it offers is the gap between population data and market pricing. Cards with low PSA 10 populations relative to total submissions — especially from older sets where the ungraded supply is largely tapped out — are the primary candidates for undervaluation. Cross-referencing that data against recent sale prices reveals where the market hasn’t caught up to the rarity. But use the tool with its limitations in mind.
Pop counts are inflated by resubmissions, they don’t reflect ungraded supply, and they change over time. The Pop Report works best as one input in a broader analysis that includes demand, cultural relevance, and your own collecting goals. Start by spot-checking cards you already own or are considering buying, then expand to set-wide analysis as you get comfortable with the data. The information is free and public — the advantage goes to the people who actually use it.
Frequently Asked Questions
Is the PSA Pop Report free to use?
Yes. The Pop Report is available on PSA’s website at no charge. You can search by sport, category, set, and card number without needing an account, though creating a free account may provide additional features.
How often does the PSA Pop Report update?
PSA updates the Pop Report on a rolling basis as cards are graded and entered into their system. There can be a delay between when your card is graded and when it appears in the report, but the data is generally current within a reasonable timeframe.
Does a low PSA 10 population automatically mean a card is undervalued?
No. Low population only indicates scarcity of graded copies at that level. If there is no collector demand for the card, or if large quantities of ungraded copies exist that could be submitted, the low pop may not translate to value. Scarcity needs to be paired with demand.
Can the Pop Report data decrease or go down?
In rare cases, yes. If PSA revokes a grade due to fraud, tampering, or error, the population can decrease. Crossovers to other grading companies after cracking out of PSA slabs also effectively remove cards from PSA’s population, though the original grade may still be counted in the report.
Should I use the Pop Report for modern Pokemon sets?
You can, but exercise caution. Modern sets are still being actively submitted, so populations are in flux. A low PSA 10 count today could increase substantially in the coming months. The Pop Report is most reliable for value analysis on vintage and older sets where submission volume has stabilized.
