You pulled something good. Maybe it's a rookie card you've been sitting on, or a card you snagged for cheap that the population report says barely anyone has graded. Either way, you're thinking about sending it to PSA. Here's everything you need to know before you do.
What PSA grading actually is
PSA (Professional Sports Authenticator) is the largest third-party grading company in the hobby. When you submit a card, they authenticate it (confirm it's real), assess its condition, and assign it a numeric grade from 1 to 10. A PSA 10 is gem mint — essentially perfect. A PSA 9 is mint with minor flaws. Most raw cards grade somewhere between 5 and 8.
The grade gets printed on a label and the card gets sealed in a hard plastic case called a slab. The slab protects the card and makes the grade permanent and verifiable by anyone.
The four grading criteria (corners, edges, surface, centering)
Corners — Flip the card under a bright light and look at all four corners. Fraying, chips, or rounding kill grades fast. This is where most cards lose points.
Edges — Run your fingernail lightly along the edges. Rough texture, chips, or nicks drop a card from a 9 to a 7 immediately.
Surface — Look at both front and back at a 45-degree angle under bright light. Scratches, print lines, stains, or creases all count. On holographic cards, look for foil wear.
Centering — PSA measures the white border from all four sides. For a PSA 10, centering needs to be roughly 50/50 or better on front, and 75/25 on back. Off-center cards are common and often uncorrectable.
How to prep a card for submission
Never clean a card with anything. Don't use your fingers, cloths, or any chemical. Handle cards by the edges only. Store them in penny sleeves inside top loaders before shipping.
Pull the card out under strong light and do your own honest assessment before submitting. Grading costs money — there's no point paying to confirm a PSA 6.
What does PSA grading cost?
PSA charges by service tier, and prices change — always check their current rate sheet. At time of writing, Economy service (slowest, 60+ business days) runs $18–$25 per card for cards valued under $499. Express and super-express tiers run much higher. For high-value cards or time-sensitive submissions, costs jump significantly.
The math: if a raw card sells for $40 and a PSA 9 sells for $120, submitting at $18 makes sense. If a raw card sells for $15 and a PSA 9 sells for $25, you're losing money. Run the numbers first.
Is it worth grading?
Depends entirely on the card. For rookie cards of stars with clean surfaces and sharp corners, almost always yes. For base set commons, almost never. For modern hits, the answer is usually: check eBay sold comps for the graded version and decide if the spread justifies the cost and wait.
The population report on PSA's site shows how many copies of each card have been graded at each grade. Low-pop 10s are often worth a dramatic premium. High-pop cards in a crowded grade are worth closer to raw.
