Graded cards are one of the fastest-growing segments of the trading card hobby. Whether you’re buying a PSA 10 Charizard as an investment, looking for a slabbed Topps Premier League auto, or considering sending your own cards off to be graded, understanding how professional card grading works will save you time, money, and mistakes.
This guide covers everything you need to know.
What Is Card Grading?
Professional card grading is the process of sending a trading card to an independent third-party company who will:
- Authenticate the card — confirm it is genuine and not a counterfeit or reprint
- Assess its condition across multiple criteria
- Assign a numerical grade, typically on a 1–10 scale
- Seal the card in a tamper-evident plastic case (a “slab”) with a label showing the grade and card details
Once graded, the card’s condition is locked in and verified. This removes the subjectivity that comes with raw (ungraded) card transactions and significantly increases buyer confidence, which is why graded cards consistently command higher prices than their raw counterparts.
The Three Main Grading Companies
PSA (Professional Sports Authenticator)
PSA is the world’s most recognised grading company and the gold standard for trading cards. Founded in 1991, PSA grades use a 1–10 scale with half grades (e.g. PSA 8.5) rarely awarded for trading cards. PSA 10 — Gem Mint — is the holy grail.
Why PSA? PSA slabs command the highest premiums on the secondary market. A PSA 10 consistently sells for significantly more than the equivalent BGS Black Label or CGC 10 for most cards. PSA’s population reports are the most widely referenced in the hobby, making it easy to assess scarcity.
Current turnaround: PSA offers tiered service levels from Economy (months) to Express (days), with pricing ranging from roughly $25 to $300+ per card depending on tier and declared value.
Note: In 2026, PSA acquired BGS (Beckett Grading Services), consolidating the two largest grading companies under one roof. BGS continues to operate as a separate brand for now.
BGS (Beckett Grading Services)
BGS uses a subgrade system that grades four individual aspects of the card separately — Centering, Corners, Edges, and Surface — then produces a composite grade. This gives buyers more information about why a card received its grade. BGS 10 Black Label (perfect 10s across all four subgrades) is extremely rare and highly coveted.
Why BGS? The subgrade transparency appeals to serious collectors. BGS Black Label is arguably the most prestigious single-card grade in the hobby. Following the PSA acquisition, some collectors are watching closely to see how BGS evolves.
CGC (Certified Guaranty Company)
CGC entered the trading card grading market in 2020 and has grown rapidly. Following PSA’s acquisition of BGS, CGC is now positioned as the primary independent alternative to PSA. CGC uses a 1–10 scale with half grades available and offers competitive turnaround times.
Why CGC? CGC is increasingly popular for football cards and modern Pokemon cards. Turnaround times are often faster than PSA at comparable price points, and CGC 10 Pristine grades are gaining recognition in the UK market.
What Does the Grade Mean for Value?
The grade has a dramatic effect on a card’s value. Here’s a rough illustration using a Base Set Charizard as an example:
- Raw Near Mint — £800–1,200
- PSA 7 — £1,200–1,800
- PSA 8 — £2,000–3,500
- PSA 9 — £4,000–7,000
- PSA 10 — £10,000–20,000+
The jump from PSA 9 to PSA 10 is where the most dramatic price difference occurs. However, PSA 10s are rare — population reports show that for many vintage cards, fewer than 1% of submitted copies receive a 10.
Should You Buy Graded or Raw?
Buy graded when:
- You’re spending significant money on a single card (£200+)
- You want certainty about the card’s authenticity and condition
- You plan to resell and want maximum liquidity
- The card is vintage and condition is hard to verify visually
Buy raw when:
- You’re building a play set or completing a set on a budget
- The card’s value doesn’t justify grading fees
- You’re buying from a reputable seller who grades accurately
- You plan to grade it yourself
Should You Grade Your Own Cards?
Grading your own cards can be highly profitable — but only if you start with the right cards in the right condition. Things to consider:
- Is the card worth grading? Grading costs roughly £20–50 per card at economy tier. If the card is only worth £30 raw, it’s rarely worth the cost and wait.
- What condition is it in? Be brutally honest. Most cards do not grade PSA 10. Even Near Mint cards often come back PSA 8 or 9.
- What grade do you need for a profit? Work backwards — if a PSA 9 sells for £100 and a PSA 8 sells for £40, and grading costs £25, you need at minimum a PSA 9 to break even.
The best candidates for grading are: modern pulls from fresh packs (handle carefully from the moment you open them), vintage cards bought raw that look exceptional, and promotional cards with low population.
