Frequently asked questions.

What does MintySlab measure?

MintySlab reports the same left/right and top/bottom centering ratios grading companies evaluate, so you can compare against published thresholds like 60/40 and 55/45.

Which cards work best?

Cards with distinct, clearly defined borders — most sports cards and TCG cards — detect best. You can also fine-tune detected edges manually anytime.

Is it on Android?

MintySlab is currently a native iOS app available on the Apple App Store. Follow MintySlab's channels for future platform news.

How is the grade estimated?

The estimate is based on measured centering. Final grades from a grading service also consider corners, edges, and surface, so treat MintySlab as a pre-submission check.
