Silver Labrador, LLC builds and published useful mobile applications. We focus on creating high-quality, native digital tools designed to provide intuitive and engaging user experiences. Our mission is to bring them directly to users through the Apple App Store, beginning with our upcoming release, Gem Chase.
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 weighs liquidity and market timing to help you organize your next grading submission.
