The short answer
ISA stands for International Sports Authentication, a third-party card grading company based in Brighton, Michigan that launched in 2010. It grades sports cards and TCG cards on a 1-10 numeric scale in a distinctive blue holder, at a fraction of what PSA, BGS, or SGC charge. ISA is a legitimate, functioning grader — the tradeoff is market recognition: an ISA-graded card typically sells for far less than the same card in a PSA holder, even at the same numeric grade.
Scale, label, and pricing
- Scale— 1 (Poor) to 10 (Gem Mint), with half-point grades available from ISA 1 through ISA 8. See how grading actually works for what centering, corners, edges, and surface mean generally.
- Label— a blue holder and label, visually distinct from PSA's red label, BGS's sub-grade box, and SGC's black holder.
- Pricing and turnaround— roughly $20 for a 20-business-day standard tier, $28 for 5 business days, and $45 for a 2-business-day rush — well under PSA's $50+ starting price for a multi-month wait.
- Resale value— the biggest gap versus the major graders. The same card in an ISA 10 holder routinely sells for a fraction of what a PSA 10 or BGS 9.5 brings, because buyer trust and liquidity are tied to the grading company as much as the numeric grade.
Should you submit to ISA?
- Check sold comps for that exact card in an ISA holder first. If you plan to resell quickly, compare an ISA listing against a PSA or BGS listing for the identical card before assuming the low submission fee is a bargain overall.
- Good fit for personal collections and bulk vintage. If you're grading for protection and display rather than resale — or submitting a large batch of lower-value cards where a $50+ PSA fee per card doesn't pencil out — ISA's price point makes sense.
- Compare against the established players in PSA vs BGS vs SGC vs CSG before deciding — for anything you plan to flip for a premium, PSA or BGS still has the deepest buyer pool.
