The Most Submitted Baseball Cards of All Time (2026 PSA Pop Report)
| By Johnny GuloWhat are the most popular baseball cards collectors have ever sent to PSA?
While million-dollar auctions often dominate headlines, PSA population reports tell a different story about the hobby. They reveal which cards collectors actually spent money grading, protecting, investing in, and preserving over time.
This study examines some of the most submitted baseball cards in PSA history and what those numbers reveal about the modern sports card hobby.
Using PSA Population Report data and hobby industry grading statistics, we analyzed iconic rookie cards, modern stars, and legendary baseball releases that collectors continue submitting year after year.
What Is the PSA Population Report?
The PSA Population Report tracks every card PSA has graded and authenticated.
Each entry shows:
- Total graded copies
- Population by grade
- PSA 10 population
- Historical submission growth
Population reports have become one of the most important research tools in the sports card hobby because they help collectors understand:
- How frequently a card has been submitted
- How difficult a card is to gem mint
- Relative scarcity
- Long-term collector demand
According to PSA, their population database updates daily and includes millions of graded collectibles across all categories.
The Sports Card Grading Explosion
The sports card grading industry has grown dramatically over the past decade.
According to hobby industry data compiled by GemRate, major grading companies graded more than 26 million cards in 2025 alone, with PSA accounting for over 19 million submissions.
This massive increase reflects how grading has transformed from a niche service into a central part of the modern hobby.
Today, many collectors automatically consider grading for:
- Key rookie cards
- Vintage stars
- Low-numbered parallels
- Autographs
- High-value modern prospects
The Most Submitted Baseball Cards Ever
Below are several of the most heavily submitted baseball cards in PSA history based on PSA Population Report data.
| Card | Total PSA Population | PSA 10 Population |
|---|---|---|
| 1989 Upper Deck Ken Griffey Jr. #1 | 45,000+ | 3,000+ |
| 2011 Topps Update Mike Trout US175 | 10,000+ | 4,000+ |
| 2018 Topps Update Ronald Acuña Jr. US250 | Massive modern population | Large PSA 10 population |
| 2019 Topps Chrome Fernando Tatis Jr. | Thousands submitted | High gem mint rate |
| 2018 Topps Chrome Shohei Ohtani | One of the most submitted modern cards | Strong PSA 10 volume |
Population figures fluctuate constantly as additional cards are submitted to PSA.
Why the 1989 Upper Deck Ken Griffey Jr. Rookie Dominates
The 1989 Upper Deck Ken Griffey Jr. rookie card remains one of the most iconic baseball cards ever produced.
Collectors have submitted tens of thousands of copies to PSA over the years because the card represents:
- The beginning of the premium card era
- One of baseball’s most beloved players
- A flagship rookie card from a groundbreaking set
- A long-term investment staple
Even with a massive PSA population, high-grade Griffey rookies continue to command strong demand throughout the hobby.
The Mike Trout PSA Population Explosion
Few modern baseball cards symbolize the grading boom more than the 2011 Topps Update Mike Trout rookie card.
Over time, collectors aggressively submitted Trout rookies chasing PSA 10 grades, causing the population to rise dramatically.
The card became:
- A modern investment icon
- A grading submission favorite
- A benchmark for modern rookie card demand
Despite the large PSA 10 population, the card continues to hold major hobby significance due to Trout’s legacy and sustained collector demand.
Population Does NOT Always Mean a Card Is Common
One of the biggest misconceptions in the hobby is assuming that a large PSA population automatically makes a card unimportant or inexpensive.
That is not always true.
Cards like:
- 1989 Upper Deck Ken Griffey Jr.
- 2011 Topps Update Mike Trout
- 1952 Topps Mickey Mantle
continue attracting collector demand because of their historical importance and cultural significance within the hobby.
Collector demand often matters just as much as scarcity.
What These Population Numbers Reveal About the Hobby
PSA population data reveals several major trends in modern baseball card collecting.
1. Rookie Cards Dominate the Hobby
Most heavily submitted baseball cards are rookie cards tied to superstar players or major prospects.
2. Modern Collectors Chase PSA 10s
Modern grading culture heavily emphasizes gem mint condition.
Many collectors submit multiple copies of the same card hoping for a PSA 10.
3. Grading Has Become Standard
Today, grading is often viewed as a normal part of collecting rather than a niche service reserved only for elite cards.
4. Population Growth Has Changed Scarcity Discussions
Collectors now debate scarcity differently than they did 15–20 years ago.
Some modern cards once viewed as “rare” now have thousands of PSA 10 copies in existence.
The Most Important Lesson From PSA Population Reports
Population reports measure collector behavior.
Every submission represents someone deciding a card was worth:
- Protecting
- Authenticating
- Investing in
- Preserving long term
That makes PSA population data one of the clearest windows into what collectors truly value.
How Collectors Use Population Reports Today
Collectors commonly use PSA population reports to:
- Research rarity
- Compare grade scarcity

- Study market trends
- Analyze long-term demand
Population reports are especially important when researching:
- Vintage baseball cards

Protecting High-Value Baseball Cards
As grading submissions continue growing, collectors increasingly focus on protecting both raw and graded cards properly.
Popular storage and display methods include:
- Soft sleeves
- Top loaders
- Card savers
- Magnetic holders
- UV-protected graded card display cases
Collectors displaying PSA slabs often use trading card display cases to help protect cards from dust, handling, and UV exposure while showcasing their collections.
