What the Population Report Tells You
PSA's free population report is the single most valuable scarcity-data source in collectibles. For every card PSA has ever graded, the report shows:
- Total submissions across all grades
- Submissions per grade tier (1 → 10)
- Submissions per qualifier (e.g. "OC" for off-center, "ST" for staining)
- Submissions per year (subscription tier)
Together that data tells you two things: how rare each grade actually is, and how the population is trending over time.
The Two Numbers That Matter
Total Pop
The total number of slabs PSA has graded for that card across all grades. Think of it as the floor on supply — if PSA pop is 10,000, there are at least 10,000 of this card in PSA holders globally.
A low total pop suggests genuine scarcity. A pop of 200 across all grades means very few people are submitting (either because the card is rare in raw form, or because nobody thinks it's worth grading).
PSA 10 Pop
The number of "gem mint" copies PSA has issued. This is the headline number for any modern collector — PSA 10 dominates the premium and drives most price discussion.
A PSA 10 pop of 200 on a chase card is very scarce. A PSA 10 pop of 30,000 means the gem-mint tier is functionally common — and the PSA 10 premium will be much smaller.
The Gem Rate
A useful derived metric: PSA 10 pop ÷ total pop = gem rate.
| Card | Total pop | PSA 10 pop | Gem rate |
|---|---|---|---|
| 1st Ed Base Charizard | 3,500 | 122 | 3.5% |
| Unlimited Base Charizard | 30,000 | 4,800 | 16% |
| Umbreon VMAX Alt Art | 70,000 | 22,000 | 31% |
| Charizard ex SIR (OBF) | 25,000 | 9,200 | 37% |
The gem rate tells you how often a submitted card grades 10. Modern cards have high gem rates because the print quality is better and submitters self-select sharp copies. Vintage cards have much lower gem rates because the print quality of 25-year-old cards is variable and even well-stored copies have whitening.
The asymmetry: a 3.5% gem rate on a card with 50 PSA 10s in existence is a different investment than a 35% gem rate on a card with 25,000 PSA 10s. The first scarcer-feeling card has 500× less supply at the top tier — the price reflects exactly that gap.
Reading the Trend
The population isn't static — it grows every time someone submits. A pop report that says "PSA 10 = 122" today might be "PSA 10 = 250" by year-end if a TikTok video sends a fresh wave of submissions.
PSA's yearly breakdown (subscription tier) is where to look:
- Flat pop year-over-year = card is "done" — most existing raw copies have already been graded
- Slowly rising pop (5–10% / year) = healthy long-term demand, modest scarcity erosion
- Sharply rising pop (50%+ / year) = something triggered a submission rush. Selling pressure is coming
- Vintage cards under +1% / year = strongest scarcity signal in the hobby
If you're holding a card and the pop is rising 30%+ annually, expect downward pressure on PSA 10 prices. If you're buying a card and the pop is essentially flat, you have a stronger thesis.
Reading the Grade Distribution
PSA's report breaks out every grade. Most useful when you compare adjacent tiers.
Healthy distribution (chase card with sustainable demand):
- PSA 10: 2,500
- PSA 9: 5,000
- PSA 8: 1,200
- PSA 7 or lower: 500
The PSA 9 pop is roughly 2× the PSA 10 — typical of well-printed modern cards. The drop to PSA 8 and below indicates lots of "borderline 10" submissions and few truly damaged copies.
Worrying distribution (oversubmitted modern card):
- PSA 10: 30,000
- PSA 9: 35,000
- PSA 8: 8,000
The PSA 10 outnumbers PSA 9 only narrowly. That means the population is dominated by very-well-printed cards being submitted in volume. The premium will compress.
Vintage distribution (Base Set Charizard Unlimited):
- PSA 10: 4,800
- PSA 9: 17,000
- PSA 8: 12,000
- PSA 7: 6,000
- PSA 6 and lower: 8,000
A long tail down the grade scale. PSA 9 is the most common grade — typical of mid-quality 25-year-old printing. This is the kind of distribution that supports a 5–10× PSA 10 premium.
The "Pop 1" Trap
A card with PSA 10 pop = 1 sounds like the rarest thing in collecting. Sometimes it is. Sometimes it's just a card nobody else has bothered grading because nobody else cares.
Before you pay a premium for a Pop 1, check:
- Total pop. If the total pop is also 1 (or under 5), nobody submitted this card and the gem-mint status reflects no demand, not real scarcity
- The card's actual demand profile. A Pop 1 PSA 10 of a Common card from a forgotten 2007 set has no buyers
- The trajectory. A Pop 1 that was Pop 0 last year suggests submissions are coming and the rarity will dissipate
The rule of thumb: scarce + in demand is what creates value. Pop 1 alone does nothing.
Using Mintlytics PSA Data
Every card on Mintlytics shows its current PSA 10 population alongside the price, and the population trends over time. The PSA Tracker ranks cards by gem rate, pop growth, and historical scarcity — useful for finding the asymmetric setups where the supply story is strongest.
A particularly useful workflow: filter modern cards by low PSA 10 pop + high recent price appreciation. That intersection — scarcity meeting demand — is where the biggest investment returns tend to live.
