주요 등급 회사 한눈에 보기
PSA는 시장 거래량에서 선두이며 특히 스포츠와 빈티지에서 강하고, 그 10은 가장 두텁고 유동성 높은 시장을 갖는 경우가 많습니다. BGS(Beckett)는 모던 카드에서 인기가 높고 서브그레이드와 인기 있는 Black Label 10으로 알려져 있습니다. SGC는 빈티지에서 강한 입지를 가지며 특징적인 검은 속지가 표식입니다. CGC는 코믹에서 출발해 수집용 카드, 특히 포켓몬 같은 TCG에서 빠르게 성장했습니다. TAG는 가장 새롭고 기술 지향적인 신규 진입자로, 컴퓨터 비전 등급과 상세한 디지털 리포트를 제공합니다.
왜 등급 회사가 가치에 영향을 주는가
같은 카드의 같은 숫자 등급이라도 회사에 따라 팔리는 금액이 다를 수 있습니다. 시장이 각 라벨의 개체 수·일관성·수요를 반영하기 때문입니다. 그래서 가치는 특정 등급 회사와 등급에 연결될 때만 의미가 있으며, 일반적인 「9」나 「10」으로는 의미가 없습니다.

Labels, slabs, and presentation
The physical slab is part of what a buyer is paying for, and each grader looks distinct on a shelf. PSA holders are instantly recognizable and ubiquitous in the hobby. SGC frames the card against a black insert that many vintage collectors prize for how it makes a card pop. Beckett slabs carry the subgrade breakdown and the well-known label colors, with Black Label reserved for the perfect cards. CGC brings the clean, professional presentation it built grading comics. TAG pairs its slab with a scannable digital report, leaning into its data-first identity.
Presentation is not just cosmetic. A consistent, trusted, tamper-evident holder supports authenticity at resale and signals to a buyer that the grade can be relied on — which is part of why the label feeds directly into value.
PSA — the volume and liquidity leader
PSA is the default for many collectors, and for a straightforward reason: scale. As the highest-volume grader across sports and vintage, it tends to have the largest pool of comparable sales, which makes its slabs easy to price and easy to sell. For blue-chip modern rookies and most mainstream sports cards, a PSA holder usually sits in the deepest, most liquid market — meaning you can convert it to cash quickly and predictably.
That liquidity is itself a form of value. When a buyer knows thousands of identical PSA-graded copies have changed hands, the price discovery is tight and the spread is narrow. For cards where you want maximum marketability and the broadest possible buyer base, PSA is frequently the safe, conventional choice.
BGS (Beckett) — subgrades and the Black Label
Beckett earned its reputation in the modern era, and its subgrades are the reason. By breaking a grade into centering, corners, edges, and surface, BGS gives buyers a more detailed picture of a card than a single number can — useful for high-end modern cards where condition nuance drives big price swings.
The Black Label sits at the top of that system: a card where every subgrade hits the top tier. Because it is genuinely hard to earn, a Black Label can carry a substantial premium over a comparable standard 10. For collectors chasing the absolute condition ceiling on a modern card, BGS offers a level of granularity and a top-end designation the other graders do not replicate.
SGC — the vintage specialist
SGC has carved out a strong, well-respected niche in vintage cards. Many vintage collectors specifically seek the SGC black insert, which frames older cardboard handsomely, and the grader is widely regarded for consistent, fair assessment of pre-modern material where surface and centering quirks are common.
For older cards, the choice of grader can matter as much as it does for moderns, and SGC is frequently the connoisseur preference in that lane. Its labels carry real weight with the vintage buyer base, which is exactly the audience that matters when those cards change hands.
CGC — TCG and comic heritage
CGC built its name grading comic books, and it brought that operational pedigree and clean presentation into trading cards. It has grown quickly in the card space, with particular traction in TCG — Pokemon above all — where its slabs are increasingly common and increasingly liquid.
For collectors focused on trading-card games rather than sports, CGC is a serious option whose market presence in that category has expanded fast. Its heritage in authentication translates into a label many TCG buyers trust.
TAG — the technology-forward newcomer
TAG represents the newest direction in grading: computer-vision assessment paired with detailed digital reports that aim to make the grade transparent and measurement-based rather than a matter of human judgment alone. The pitch is consistency and data — a buyer can see the underlying analysis instead of trusting a number on faith.
As the most recent entrant, TAG is still building its market footprint relative to the established graders, so its resale liquidity is earlier in its development. For collectors who value transparency and are comfortable being early to a newer standard, it is an intriguing choice — and one whose role in the hobby is still being written.
How grader choice affects resale value and liquidity
The same card in the same numeric grade can sell for different amounts across companies, because the market prices in each label population, consistency, and demand. A grader with a deep, active market for a given card type gives you tighter pricing and faster sales — that is liquidity, and it is real money when you need to sell. A thinner market can mean a wider spread between what a card is theoretically worth and what a buyer will actually pay this week.
This is why a value is only meaningful when it is tied to a specific grader and grade — never a generic 9 or 10. A PSA 10, a BGS Black Label, an SGC 10, and a TAG 10 of the same card are four different assets with four different markets. Treating them as interchangeable is how collections get mis-valued and under-insured.
How to decide which grader to use
Match the grader to the card and the goal. For mainstream sports and modern blue-chip cards where you want maximum liquidity and the broadest buyer pool, PSA is the conventional, safe pick. For high-end modern cards where condition nuance matters and you want to chase the absolute ceiling, BGS subgrades and the Black Label are hard to beat. For vintage, SGC commands real respect with the buyers who matter in that lane. For TCG and Pokemon, CGC has fast-growing traction. For transparency and a data-first read, TAG is the forward-looking option, with the caveat that its market is younger.
Two more practical inputs round out the decision: how a card already sells at each grader in its category, and what you intend to do with it. A card you plan to hold and insure has different priorities than one you plan to flip quickly. Look at where comparable sales are deepest for that specific card before you commit — the market will tell you which label it rewards.
Slabline values cards from every major grader
Whichever grader you choose, the slab still needs to be valued, tracked, and protected — and that is the same problem across all of them. Slabline values cards graded by PSA, BGS, SGC, CGC, and TAG, each at its specific grade, from real comparable sales. Scan the slab label and the grader and certification number are read automatically, returning a value that reflects exactly what you own rather than a generic price-guide figure.
From there, every slab — regardless of which company graded it — lives in one place, with a collection-wide 0-to-1000 protection score across insurance, concentration, storage, liquidity, and provenance, plus a broker-ready insurance schedule built from those live values. Slabline is not an insurer or a broker, and its values are estimates from recent comparable sales, not a certified appraisal. You can build your own score free for up to 25 cards and see every grader you own, side by side, in a single view.
