Population reports are among the most valuable resources for coin dealers. These databases track every coin certified by PCGS and NGC, revealing exactly how many examples exist at each grade level. This information is essential for understanding condition rarity and pricing coins appropriately.
Yet many dealers underutilize population data. They check a number but don't know how to interpret it in context. Is a population of 50 significant? What about 500? How do population patterns affect pricing strategy?
This guide explains how to read, interpret, and apply population report data to your pricing decisions. You'll learn to identify condition rarities, spot value opportunities, and price inventory with data-driven confidence.
What Are Population Reports?
Population reports are databases maintained by grading services tracking all coins they've certified:
PCGS Population Report

What Population Reports Show
| Data Element | Meaning | Pricing Relevance |
|---|---|---|
| Population at grade | Number certified at specific grade | Core scarcity measure |
| Plus grade population | Number with + designation | Subset scarcity |
| Higher grades | Population at grades above | Condition ceiling context |
| Total certified | All grades combined | Overall type availability |

Reading Population Reports
Sample Population Grid
A typical population report displays grades in columns:
| Date/Variety | MS-63 | MS-64 | MS-65 | MS-66 | MS-67 |
|---|---|---|---|---|---|
| 1881-S | 5,234 | 8,127 | 4,891 | 1,247 | 89 |
| 1893-S | 127 | 89 | 34 | 8 | 1 |
Notice the dramatic population difference between the common 1881-S and key date 1893-S, plus how populations decline at higher grades.
Interpreting the Numbers
- High populations (1,000+): Common in this grade—price guides usually accurate
- Moderate populations (100-1,000): Available but not abundant
- Low populations (10-100): Scarce—may warrant premium over guides
- Very low populations (1-10): Condition rarity—market sets price
Plus Grade Data
Population reports often show plus grades separately:
| Grade | Standard | Plus (+) | Total |
|---|---|---|---|
| MS-65 | 4,200 | 691 | 4,891 |
| MS-66 | 1,100 | 147 | 1,247 |
Plus grades are subsets—the 691 MS-65+ coins are more scarce than the 4,891 total at MS-65.
Understanding Condition Rarity
What Makes a Coin Condition Rare?
Condition rarity exists when a coin is common overall but rare in high grades:
- Many certified total: Type is available
- Few at top grades: Finding gem examples is difficult
- Steep population drop: Population decreases dramatically at higher grades
Identifying Condition Rarities
Condition Rarity Indicators
Look for dramatic population drops between grades. If MS-65 has 500 and MS-66 has 20, that MS-66 is a condition rarity even if the coin is "common" overall. The 25:1 ratio signals significant scarcity at the higher grade.
Condition Rarity Pricing
| Population at Grade | Condition Status | Pricing Approach |
|---|---|---|
| 500+ | Common at grade | Standard price guide |
| 100-500 | Available | Price guide, minor adjustment |
| 20-100 | Scarce | Above price guide, research sales |
| 5-20 | Rare at grade | Well above guide, auction research |
| 1-5 | Condition rarity | Market-driven, significant premium |
Pricing Applications
Using Population for Initial Pricing
- Check price guide: Get baseline retail value
- Look up population: Find certified population at grade
- Assess scarcity: Is this common or condition rare?
- Adjust pricing: Premium for scarce, standard for common
- Research sales: Verify with recent auction results
Premium Adjustments by Population
| Population Level | Suggested Premium Over Guide |
|---|---|
| 500+ | 0% (use guide) |
| 100-500 | 0-10% |
| 50-100 | 10-25% |
| 20-50 | 25-50% |
| 10-20 | 50-100% |
| Under 10 | Research required—may be 100%+ |
Comparing to Higher Grades
Consider the coin's position relative to finer examples:
- Many finer exist: Grade isn't the ceiling—standard pricing
- Few finer exist: Near top of census—premium potential
- None finer: Finest known—significant premium
Finest Known Premium: Coins ranked #1 at a grade with nothing finer can command 2-5× or more the price of "just" high-grade examples. Registry collectors pay for position.
Common Population Patterns
Pattern 1: Normal Distribution
Most grades cluster around MS-63/64 with declining populations at extremes:
- MS-60-62: Moderate population
- MS-63-64: Highest populations
- MS-65-66: Declining populations
- MS-67+: Rare populations
Pattern 2: Modern Coin Skew
Modern coins often cluster at MS-69/70:
- MS-65-68: Low populations (most go higher)
- MS-69: Very high population
- MS-70: High population (but lower than 69)
For moderns, MS-69 is "common" and MS-70 carries the premium.
Pattern 3: Weak Strike Issues
Some issues rarely show full detail:
- Standard grades: Normal populations
- Full designation (FB, FH, etc.): Much lower
- Example: Mercury Dime with 500 at MS-65, only 50 as MS-65 FB
Pattern 4: Original vs. Resubmission Heavy
Some dates show inflated populations from resubmissions:
- Popular dates get submitted repeatedly
- Population may overstate actual surviving coins
- Consider "unique coins" vs. "grading events"
Data Limitations
Resubmissions Inflate Numbers
Population counts grading events, not unique coins:
- Crossovers: Same coin counted at both services
- Reholders: Same coin counted multiple times
- Upgrade attempts: Repeated submissions seeking higher grade
- Impact: True surviving population lower than reported
Population Reality Check
A reported population of 100 doesn't mean 100 unique coins exist. Resubmissions mean the actual number of unique coins is lower—sometimes significantly lower for popular resubmission targets.
Not All Coins Are Certified
Population only counts certified coins:
- Raw coins exist: Many high-grade coins never submitted
- Collections: Some collectors never certify
- New discoveries: Hoards or collections enter market
- Impact: Population understates total surviving coins
Historical Data Gaps
- Pre-1986 coins: Grading services didn't exist
- Early data: May be incomplete or use different standards
- World coins: Many not yet certified
Advanced Population Analysis
Comparing PCGS and NGC
Add both populations for fuller picture:
- Combined population: PCGS pop + NGC census
- Market reality: Both service coins compete in market
- Crossover discount: Some coins counted at both services
Tracking Population Changes
Monitor populations over time:
- Growing populations: More coins being certified
- Stable populations: Most examples already graded
- Supply impact: Rapid growth may pressure prices
Grade Distribution Analysis
Calculate ratios between grades:
- MS-65 to MS-66 ratio: Indicates difficulty of achieving MS-66
- Large ratio (10:1+): Significant condition rarity
- Small ratio (2:1): More normal progression
Key Takeaways

What is a coin population report?
A population report is a database maintained by grading services (PCGS and NGC) that tracks every coin they've certified. It shows how many coins have been graded at each grade level for every date and variety. This data helps determine rarity and appropriate pricing for certified coins.
Where can I access PCGS and NGC population data?
PCGS Population Report is available free at pcgs.com/pop. NGC Census is available free at ngccoin.com/census. Both allow searching by denomination, date, variety, and other criteria. You can also see population data when verifying specific certification numbers.
What is condition rarity?
Condition rarity refers to coins that are common overall but rare in high grades. A date might have thousands certified total but only a few dozen in MS-66 or higher. These high-grade examples are condition rarities and command significant premiums even though the date itself isn't rare.
How do population reports affect pricing?
Low populations indicate scarcity, which justifies pricing above standard price guides. High populations suggest the coin is common at that grade, so standard pricing applies. Condition rarities with populations under 10-20 may warrant 50-100%+ premiums over guides. Always combine population data with actual sales research.
Why doesn't population equal the actual number of surviving coins?
Population reports count grading events, not unique coins. The same coin may be counted multiple times through crossovers, reholders, and upgrade attempts. Additionally, many high-grade coins have never been certified. Actual surviving populations are typically lower than PCGS/NGC combined numbers suggest.
What population is considered rare?
Populations under 100 start to indicate meaningful scarcity. Under 50 is scarce. Under 20 is rare. Under 10 is very rare and likely a condition rarity. Under 5 is extremely rare. These thresholds vary by series—some popular series have high populations throughout, making even 100 relatively scarce.
Should I combine PCGS and NGC populations?
Yes, for market analysis. Buyers consider both PCGS and NGC coins when making purchases. Adding both populations gives a more complete picture of market supply, though some coins may be counted at both services due to crossovers. Combined data better reflects the competitive landscape.
How do I use population data for pricing?
Start with price guide value, then check population. If population is high (500+), use guide pricing. For moderate populations (50-500), consider small premiums. For low populations (under 50), research recent sales and price above guides. For very low populations (under 10), market sets price—research comparable sales carefully.
What does "finest known" mean in population reports?
Finest known means no examples have been certified at a higher grade. Being #1 on the population report carries significant premium—registry collectors compete for top positions. A finest known coin might sell for 2-5× or more the price of examples just one grade lower.
Do population reports include raw coins?
No, population reports only count certified coins. Many high-grade coins exist that have never been submitted to grading services. This means population reports understate total surviving coins while overstating certified supply due to resubmissions. Raw coin availability varies widely by series.
