Proprietary grading metric
Gem Rate for Pokemon card grading decisions
Gem Rate helps collectors understand whether a card is a strong grading candidate by combining condition signals with value upside.
What is Gem Rate?
Gem Rate is PocketGrader.ai's proprietary pre-grade signal. It combines visible condition, centering, likely grade limiters, and value context to estimate how attractive a card is as a grading candidate.
