Selling cards for a living?
The workflow tier: bulk photo grading, collection export, real-sold-comps pricing and a straight path from scan to eBay listing. Subscriptions are for workflows — this is the one thing worth paying monthly for.
Founding members lock the launch price for life.
The 2-grade guarantee
If a CardGradeCheck estimate misses the final professional grade — PSA, BGS, CGC or SGC — by more than 2 full grades, we credit that grade back. Send the slab photo and your original result. We publish honest ranges precisely so this rarely happens; when it does, it's on us, not you.
Why credits and not a subscription? Because you rip a hobby box twice a quarter, not twice a day. Charging monthly for occasional use is how tools farm forgotten renewals — we'd rather you buy 25 grades once and think of us the next time a chase card hits your desk.
FAQ
Is CardGradeCheck free?
The centering tool and worth-grading calculator are free forever, no signup. AI grading gives every visitor 3 free estimates a month; credit packs cover anything beyond that.
Do credits expire?
Never. Buy once, use whenever the next pull deserves it.
What do I need to buy credits?
Just an email — you sign in with a one-time code, no password to remember. Credits attach to your email and work on any device.
What if the estimate is wrong?
Off by more than 2 grades against the professional result → the credit comes back. That's the guarantee, and it's the whole product philosophy: honest ranges beat confident nonsense.
Can I pay for a single grade?
The smallest pack is 10 grades for $4.99 — below that, card processing fees eat the transaction. Your 3 monthly free grades exist exactly for the one-off card.
