Buy Raw. Grade Smart.

Data-Driven Grading Intelligence

Gem Chase provides a structured look at the sports card market for collectors who buy raw and sell graded. By processing price gaps, gem rates, and seasonal market trends, the app identifies cards with significant spreads between raw and PSA-graded values. Our goal is to replace "gut feel" with a systematic approach, using an algorithm that factors current margins, liquidity and market timing to help you organize your next grading submission.

Analytical Tools for Flippers

Built for speed and accuracy, Gem Chase includes a net-return simulator that factors in marketplace fees, grading costs, gem rates and time to grade. Beyond the numbers, the platform offers specialized views like "Mint Yields" for cards that show profit potential at a PSA 9 grade, and our "Gem Chasers" list for cards with high gem rates and profit spreads. It is a streamlined dashboard designed to help you track price movement with professional-grade data.
