Quick Answer: How Many Card Grading Companies Exist?
10+ regional/specialty graders serve niche markets and local regions
The card grading industry has expanded significantly since PSA launched in 1991 as the first third-party authenticator. Today, collectors have more options than ever — from established giants to emerging AI-powered services.
However, not all grading companies are equal. The "Big 5" majors dominate market share and resale value, while smaller graders serve specific niches or geographic regions.
The Big 5 Major Card Grading Companies
These five companies process approximately 95% of all graded cards globally and command the strongest resale values:
Cards Graded: 40+ million
Market Share: ~60%
Specialty: Modern cards, registry sets
Cards Graded: 15+ million
Market Share: ~15%
Specialty: Sub-grades, Black Label
Cards Graded: 3+ million
Market Share: ~8%
Specialty: TCGs, comics crossover
Cards Graded: 500K+
Market Share: ~2%
Specialty: AI-powered, digital reports
Regional & International Grading Companies
Beyond the Big 5, several companies serve regional markets where shipping to US graders is expensive or impractical:
| Company | Region | Est. | Notes |
|---|---|---|---|
| ACE Grading | UK | 2020 | European alternative to US graders |
| ISA | USA | 2010 | Budget option, limited resale market |
| GMA Grading | USA | 2000s | Very low cost, minimal resale value |
| KSA | Canada | 1996 | Canadian market focus |
| PCA | UK | 2010s | European collector market |
| GetGraded | UK | 2021 | UK/EU focused, growing rapidly |
| AGS | USA | 2019 | AI-assisted grading system |
Note: Regional graders offer convenience for local collectors but typically have weaker resale markets in the US. Use for PC (personal collection) cards rather than investment pieces.
Specialty & Niche Grading Services
Some graders focus on specific card types rather than general sports cards:
- CSG (Certified Sports Guaranty) — Autograph authentication and signed cards division of CGC
- DNA Autograph Authentication — PSA's autograph verification service for signed items
- JSA (James Spence Authentication) — Premier autograph authenticator, works with card graders
- Beckett Vintage Grading (BVG) — BGS division specifically for pre-1981 cards
- AGS (Automated Grading Systems) — AI-first grading with machine learning focus
Emerging AI-Powered Grading Companies
The AI grading revolution has spawned numerous tech-focused startups:
| Company | Approach | Status |
|---|---|---|
| PreGradeCards | Pre-screening AI | Active — 89% PSA accuracy |
| CardGrade.io | Mobile AI app | Active — 3 free scans |
| TAG Grading | Hybrid AI + Human | Active — Limited tiers |
| AGS | Full AI grading | Active — Low volume |
| GradeAI | Computer vision | Beta testing |
| CardScan Pro | AI estimation | Active — Portfolio tool |
Caution: Most AI grading tools are pre-screening services, not professional graders. Only TAG and AGS offer actual slabbed grading with resale markets. Use AI tools to decide whether to grade, not as a replacement for PSA/BGS/SGC.
Inactive or Paused Grading Services (2026)
Several grading companies have paused or closed services due to capacity constraints in 2026:
Currently Paused/Closed:
- PSA Value Tiers: Value Bulk, Value, Value Plus, Value Max — paused June 2, 2026
- TAG Standard Tiers: Basic, Standard, Express — closed to capacity May 2026
- CGC Bulk: Extended turnaround to 120+ days due to backlog
- HGA: Reduced capacity, longer turnaround times
These pauses highlight the industry's capacity challenges. When asking "how many grading companies are there," the practical answer depends on which are currently accepting submissions.

Grading Company Market Share in 2026
Not all 15+ grading companies are equal in market power. The graded card market is heavily concentrated among the top players, and market share directly affects resale value.
| Company | Estimated Market Share | Primary Strength |
|---|---|---|
| PSA | ~70% | Resale premiums, market trust |
| BGS | ~15% | Sub-grades, modern condition detail |
| SGC | ~8% | Vintage, tuxedo slabs, value |
| CGC | ~5% | TCG, Pokemon, Magic |
| All Others | ~2% | Niche/regional markets |
Why market share matters: a PSA 10 typically sells for more than a BGS 9.5 or SGC 10 of the same card, even if the condition is identical. The brand on the slab carries value. Collectors choosing between graders should weigh the cost of grading against the expected resale premium.
How to Choose From 15+ Grading Options
With so many options, here's a decision framework:
For Maximum Resale Value
Choose PSA, BGS, or SGC. These three command the strongest premiums in the secondary market. PSA leads for modern, SGC for vintage, BGS for sub-grade transparency.
For Budget Grading
Consider CGC ($15 bulk) or ISA/GMA for low-value cards where resale isn't the priority. Note: Budget graders have weak secondary markets.
For Pre-Screening
Use PreGradeCards (89% accuracy) to identify which cards are worth sending to professional graders. This saves hundreds in wasted submission fees.
For UK/EU Collectors
Try ACE, PCA, or GetGraded to avoid international shipping costs. However, expect lower resale values than US-graded cards.
Frequently Asked Questions
How many card grading companies are there in the US?
There are approximately 10 card grading companies based in the United States: PSA, BGS, SGC, CGC, TAG, ISA, GMA, AGS, and several smaller AI-powered services. The "Big 5" (PSA, BGS, SGC, CGC, TAG) process over 95% of all graded cards in the US market.
What is the oldest card grading company?
PSA (Professional Sports Authenticator) is the oldest card grading company, founded in 1991. They created the 1-10 grading scale that became the industry standard. Prior to PSA, collectors relied on dealer opinions and raw card sales without standardized condition assessment.
Are there any free card grading companies?
No professional grading companies offer free grading — all charge per-card fees ranging from $15 (CGC bulk) to $300+ (PSA expedited). However, AI pre-grading apps like PreGradeCards offer free tiers (5 scans/month) to help collectors pre-screen cards before paying professional fees.
Which grading company is the strictest?
SGC and BGS are generally considered stricter than PSA for Gem Mint 10 grades. SGC's 10 Pristine requires perfection across all factors. BGS 9.5 (Gem Mint) with all sub-grades 9.5+ is roughly equivalent to PSA 10 in strictness. PSA is known for being slightly more lenient on centering and surface for modern cards.
Can I start my own card grading company?
Technically yes, but establishing market credibility takes years and significant capital. New graders need: (1) Expert staff with grading experience, (2) $500K+ in authentication equipment, (3) Insurance and legal infrastructure, (4) Years to build resale market trust. Most new entrants focus on AI-assisted pre-screening rather than full professional grading.
Why are there so many grading companies now?
The grading boom of 2020-2021 created massive demand that exceeded PSA's capacity. New companies emerged to capture overflow: BGS and SGC expanded, CGC entered cards, TAG launched AI-assisted grading, and numerous regional options appeared. The 2026 PSA Value pause (at $79.99) continues driving collectors toward alternatives.
What are the biggest card grading companies by market share?
PSA holds approximately 70% of the graded card market, followed by BGS at ~15%, SGC at ~8%, and CGC at ~5%. All other grading companies combined make up less than 2% of the market.
Is it worth using a smaller grading company?
Smaller companies can be worth using for budget grading, local convenience, or niche card types. However, their slabs usually command lower resale prices than PSA, BGS, or SGC. Use them when cost matters more than resale value.
How do I choose between PSA, BGS, and SGC?
Choose PSA for maximum resale value on modern cards, BGS for sub-grade transparency and modern cards, and SGC for vintage cards and budget-conscious grading. Pre-screen with PreGradeCards to identify which cards are worth sending to any of them.
What is the cheapest professional card grading company?
CGC bulk tiers start around $15 per card, and ISA/GMA offer budget tiers around $10-20. However, these companies have weaker resale markets. PSA is $79.99 per card in 2026 but commands the highest premiums.
