Any card you buy
Sports or non-sports, vintage or modern. Upload a front and a back photo and that is all it needs.
About a minute
Two photos in, an estimated grade out, in about a minute.
Four parts, read apart
Centering, corners, edges and surface each get their own score, so you see what holds a card back.
A plain confidence level
Every estimate says how sure it is, and says straight whether a 10 is really there.
How it works
From two photos to a straight answer

Send the pair to GemGrade. There is nothing to type in and no card details to fill out.

Read the estimate
In about a minute you get an estimated grade, a score for each of the four parts, and a confidence level.
