Leveraging PSA Population Reports to Identify Undervalued Cards
By KOLT, Senior Analyst at KLLKT.in
Why PSA Population Reports Matter
PSA population reports provide critical data on how many copies of a specific card have received a particular grade. In a market where scarcity drives premiums, these reports reveal true supply levels for high-grade examples. Cards with low PSA 10 populations often command outsized prices relative to raw versions because collectors compete for limited supply. When population figures remain low, even modern or lesser-known issues can represent undervalued opportunities for investors who act before broader awareness increases demand. This data separates hype from actual scarcity, allowing analysts to spot cards where the graded premium exceeds what current population numbers would justify.
How to Read PSA Population Reports
Access reports directly through the PSA website by entering the card’s set, year, player, and card number. The report displays cumulative populations for each grade, including PSA 10, PSA 9, and lower tiers. Focus primarily on the PSA 10 column, as this grade captures the highest collector demand. Compare the population figure against total print run estimates and recent sales data. A low PSA 10 count relative to the number of raw cards available signals potential undervaluation. Track historical population growth over time to identify cards that have not yet seen significant grading volume. Cross-reference with auction results to confirm whether the current PSA 10 price reflects the reported scarcity or lags behind it.
Top Low-Pop Opportunities with Current Data
Several recent and vintage cards show notable PSA 10 price premiums against raw values, with population reports currently listed as unknown. These discrepancies highlight areas where low PSA 10 counts could create buying opportunities once verified.
| Card | PSA 10 Price | Raw Price | Premium Ratio |
|---|---|---|---|
| Walter Payton 1978 Topps Football | $6,773.46 | $8.28 | ~818x |
| Cooper Flagg 2025 Topps Basketball | $376.71 | $87.90 | ~4.3x |
| Victor Wembanyama 2025 Topps Chrome Basketball | $103.93 | $4.23 | ~24.6x |
| Cleffa 2023 Pokemon Scarlet & Violet Obsidian Flames | $415.76 | $33.37 | ~12.5x |
| Kon Knueppel 2025 Topps Basketball | $353.65 | $25.38 | ~13.9x |
| Victor Wembanyama 2025 Topps Finest Basketball | $292.82 | $18.70 | ~15.7x |
| JoJo Parker 2025 Bowman Draft Chrome Baseball | $82.91 | $5.52 | ~15.0x |
| Bobby Witt Jr. 2026 Topps Baseball | $43.63 | $1.07 | ~40.8x |
The Walter Payton example stands out for its extreme premium, suggesting that even modest PSA 10 populations could support strong returns. Newer prospects like Cooper Flagg and Kon Knueppel display solid multiples despite unknown populations, indicating possible scarcity in top grade. Pokemon and baseball rookies follow similar patterns, where raw prices remain accessible while graded 10s trade at meaningful markups.
What to Watch For
Unknown population figures require caution. High premiums can stem from collector hype rather than confirmed scarcity, so verify populations as soon as new reports update. Condition sensitivity varies by set—some modern cards receive high grades more easily, inflating populations quickly. Market liquidity also matters; thinly traded cards may show inflated PSA 10 prices that do not hold during broader sales. Watch for sudden population spikes after major grading submissions, which can erase premiums overnight. Always factor in set popularity and player performance trends before assuming low population equals automatic value.
Action Steps
Begin by monitoring PSA’s population database weekly for the listed cards and similar issues. Calculate premium ratios regularly using recent sold listings. When a card shows a high multiple and still-unknown PSA 10 population, consider acquiring raw copies in strong condition for future grading. Set price alerts on marketplaces to capitalize on temporary dips. Document population changes alongside price movements to build a personal database of proven opportunities. Focus first on the highest-ratio examples like the Walter Payton and Bobby Witt Jr. cards, then expand to prospects with emerging collector interest. Consistent tracking of these metrics positions investors to act ahead of wider market recognition.
