Grading exists to solve one problem: "mint" means something different to every seller. A third-party grading company puts a card through a standardized review, seals it in a tamper-evident holder, and assigns a number that the entire market agrees to treat as objective — even though, underneath, it's still a human being's trained judgment call. Three companies dominate the sports card side of the hobby, and they don't grade the same way.
PSA
PSA is the company most collectors default to first, largely because it has the deepest population report data and the strongest resale liquidity — a PSA-graded card is usually the easiest one to sell quickly at a fair price, simply because more buyers trust and recognize the label. PSA's 1–10 scale weighs centering, corners, edges, and surface, but tends to be somewhat more forgiving on centering than BGS. For vintage cards especially, PSA's grading has become something close to the industry's reference standard.
BGS (Beckett)
BGS is known for two things: sub-grades and stricter centering standards. Instead of one overall number, BGS assigns individual sub-grades for centering, corners, edges, and surface, then calculates a composite. That transparency is genuinely useful — you can see exactly why a card graded an 8 instead of a 9 — but it also means BGS grades tend to run tighter than PSA on the same card, particularly on centering. A BGS 9.5 with a "Black Label" 10 across every sub-grade is one of the most sought-after distinctions in modern grading precisely because BGS's bar for a true 10 is so high.
SGC
SGC has built a strong reputation specifically in vintage grading, and its newer holder design has become popular enough that some collectors specifically seek out SGC-graded vintage over PSA for aesthetic reasons alone. SGC's grading tends to be viewed as comparable to PSA on vintage cards, sometimes considered a touch more consistent on cards with print or manufacturing-era imperfections that are common to a whole print run rather than damage.
What actually drives the grade, regardless of company
- Centering. How evenly the image sits within the card's borders, viewed front and back. This is usually the single biggest factor separating a 9 from a 10.
- Corners. Sharp corners grade higher; even microscopic softness gets caught under magnification.
- Edges. Chipping or roughness along the cut, often invisible to the naked eye but obvious under a loupe.
- Surface. Scratches, print lines, wax stains, or gloss loss. This is where factory print-era issues most often cost vintage cards a full grade.
Turnaround time and cost
All three companies offer tiered service levels — a cheaper, slower "economy" tier and progressively faster, more expensive tiers for time-sensitive submissions. Turnaround and pricing change often enough industry-wide that we won't print specific numbers here; check each company's current submission page directly before you commit, and factor return shipping and insurance into your real cost, not just the stated grading fee.
So which one should you actually use?
A practical way to decide:
- Modern cards you plan to resell quickly — PSA, for the liquidity.
- High-value cards where you want maximum transparency on exactly what's costing you points — BGS.
- Vintage cards, especially anything pre-1980 — SGC or PSA, both well-regarded; compare current population reports for your specific card before choosing.
The grading company doesn't change what the card is. It changes how fast and how confidently someone else will buy it from you.
Before you submit anything, it's worth applying the same scrutiny covered in our piece on spotting fakes and reprints — a grading company will catch an altered or counterfeit card, but you'll save yourself the submission fee and the wait by catching it first.
Talk to dealers before you ship
One of the most underused resources for a new collector deciding how to grade is simply asking working dealers at a show floor. Most have submitted hundreds of cards across all three companies and have real opinions about which one made sense for which type of card — opinions that are more current than anything written six months ago, this piece included.
