The decision of which grading service to use can mean a 30-50% difference in resale value. Here is the complete 2026 comparison covering trading cards, sports cards, and TCG.
The four major services at a glance
| Service | Founded | Strongest in | Market premium |
|---|---|---|---|
| PSA | 1991 | Vintage sports, Pokémon, modern sports | Highest (baseline) |
| CGC | 2000 (cards 2020) | Comics, video games, TCG, modern Pokémon | 10-30% below PSA |
| BGS (Beckett) | 1999 | Modern sports, autographs, MTG | 15-25% below PSA except BGS 9.5/10 |
| SGC | 1998 | Vintage cards, oddball categories | 5-20% below PSA |
PSA (Professional Sports Authenticator)
PSA dominates the trading card grading market with approximately 70% of high-end activity. PSA-graded cards consistently set auction records. Their grading scale: PSA 1 (Poor) to PSA 10 (Gem Mint), with no half-grades on cards (BGS-style 9.5 doesn’t exist for PSA).
Pros: highest market premiums, deepest sales database (Auction Prices Realized), strongest brand recognition, fastest sales liquidity. Cons: 30-300 day turnaround at peak, $20-150+ per card, slot availability constraints during 2021-2023 backlog.
Best for: Pokémon, vintage sports cards, modern hits intended for resale at six-figure price points.
CGC (Certified Guaranty Company)
CGC entered cards in 2020 after dominating comics for two decades. CGC introduced quarter-grade increments (PSA 9.5 equivalent) and is the leading grader for video games and sealed product. They often grade more strictly than PSA on centring.
Pros: faster turnaround (often 7-30 days), good for video games and TCG, half-grade granularity. Cons: 10-30% lower market premium than PSA on equivalent grade.
Best for: comics (industry standard), video games (industry leader), modern Pokémon and One Piece TCG, sealed product, signed cards.
BGS (Beckett Grading Services)
BGS uses a 0.5-increment scale with separate sub-grades for centring, corners, edges, and surface. BGS 9.5 (“Gem Mint”) and BGS 10 (“Pristine”) command premiums over PSA 10 in the Magic: The Gathering and high-end sports market.
Pros: sub-grades give granularity, MTG and modern sports are BGS strongholds, BGS 10 Pristine is the rarest grade. Cons: below PSA on Pokémon and most other categories, slower turnaround than CGC.
Best for: Magic: The Gathering, modern sports cards, autographed cards, anything with a chance at BGS 10 Pristine.
SGC (Sportscard Guaranty Corporation)
SGC focuses heavily on vintage sports cards and uses a black slab with a gold logo. They grade more strictly than PSA on edges, often resulting in lower scores than PSA. The market accepts SGC at slightly below PSA pricing for equivalent grades.
Pros: fast turnaround, strong reputation in vintage, less subjective grading. Cons: 5-20% market discount to PSA, lower volume = thinner price discovery.
Best for: vintage sports cards (1900s-1970s), oddball categories that PSA grades inconsistently.
Decision tree
- Pokémon, vintage baseball, vintage football, modern hits → PSA.
- Comics, video games, sealed product, signed cards → CGC.
- Magic: The Gathering, modern sports with chance at Pristine → BGS.
- Pre-1980 vintage sports with strict centring concerns → SGC.
- Cross-grading is rarely worth the time and cost — pick once and commit.
FAQ
Can I cross a CGC card to PSA?
Yes — PSA’s “Crossover Service” cracks the existing slab and re-grades. There is risk of a lower grade (the new graders may disagree). Cross only if you’re confident the existing grade is conservative.
Why do PSA-graded cards sell for more than CGC-graded?
Liquidity, buyer familiarity, and depth of comparable sales data. The market trusts PSA’s gem-mint label more than competitors at top grades.
Should I grade my common Pokémon card?
Almost never. Grading costs $20-50; the card needs to be worth $200+ raw to make sense. Common cards lose money on grading even at PSA 10.
What’s the cheapest grading service?
SGC and CGC are usually the cheapest at the bulk tier ($15-25 per card). PSA bulk grading (when available) is $20-30 per card. Walk-in / express grading at any service costs $100-1,000+.

Frequently Asked Questions
Is this grading guide suitable for beginners?
Yes — this guide is written to be accessible to new collectors while remaining useful for intermediate enthusiasts. We layer foundational concepts with practical examples, expected price ranges, and authentication checkpoints so you can read once and reference repeatedly. If you are completely new, we recommend reading our beginner’s roadmap (/start-here/) alongside this material.
How current is the information in this grading guide?
This guide reflects 2026 market conditions, grading standards, and authentication best practices. We periodically refresh content as auction records, grading-service criteria, and counterfeit techniques evolve. The guide’s last-updated timestamp shown by your browser corresponds to our most recent factual review.
What’s the most common mistake collectors make in grading?
Buying before learning. The hobby rewards patience: collectors who spend the first 60-90 days reading, attending shows, watching auction results, and asking questions in established communities consistently outperform those who buy aggressively from day one. Education compounds; impulse purchases rarely do.
Where can I get items in grading authenticated?
For most categories, established third-party authenticators include PSA, BGS, CGC, and SGC for cards; PCGS and NGC for coins; BBCE for sealed Pokémon and sports wax; AFA for toys; and recognized industry experts or auction-house specialists for watches, autographs, and fine collectibles. Independent verification typically costs $20-$200 and is well worth it for any item over $500. See our /authentication-hub/ for category-specific recommendations.
How do I sell grading for the best price?
Match the venue to the value. Items under $100: eBay or Facebook collector groups. Items $100-$1,000: eBay with strong photography and detailed descriptions, or category-specific platforms (StockX, Discogs, Catawiki). Items over $1,000: established auction houses (Heritage, Goldin, Christie’s, Phillips) or vetted dealer consignment. Avoid pawn shops (typical offers: 20-40% of fair value) and unverified buyers offering instant cash.
