About GradeOrFlip
GradeOrFlip is an independent project owned and run by Matt, a person, not a company or news organization. It is a free, no-signup tool site: Grade it or flip it raw? Know before you ship.
Purpose
I built GradeOrFlip to help people work out whether to grade a trading card or sell it raw with real numbers instead of guesses. The calculators run in your browser, show their formulas, and let you change every assumption. The guides explain the numbers behind the tools in plain language.
Data sources
Grading fees, turnaround times and tiers come from the public pricing pages of PSA, SGC, Beckett (BGS) and CGC, and eBay fee figures come from eBay's published fee schedule. Each figure on the fee pages shows its source and the date we last checked it. Fees change often, so confirm on the grader's own site before you submit. Your card values, grade odds and resale prices are your own inputs; we do not look up card prices.
How we keep it accurate
The math is covered by automated tests with hand-computed answers, figures show their source and update date where possible, and the site was last updated October 14, 2026. If you spot an error, please tell me and I will fix it.
Disclaimers
