Who's Behind This
Howdy, I'm Andrew.
I'm a collector who got frustrated with the lack of real data available to people like us. Grading companies publish population reports but don't tell you what they mean for your wallet. Marketplaces show you prices but not whether those prices justify the cost of getting there.
the Card Calculus² is what happens when you point math at an industry that runs on vibes. No affiliations with any grading company or marketplace.
