Building Moonstone: Bloomberg Terminal

About

I built Moonstone to price Pokémon cards on what they actually sell for: binder-page scans priced from real sold data, PSA populations and gem rates, movers and indexes, and break-even grading math that tells you when grading pays — and when to sell raw. Scan 1,000 cards free at moonstonehq.com/scan.

Moonstone - The Bloomberg Terminal for Pokémon Cards

Point your phone at a binder page and Moonstone prices every card on it from real sold data — no typing, no one-card-at-a-time lookup. Scan 1,000 cards free: moonstonehq.com/scan Under the scan: eBay sold-price medians, PSA populations and gem rates, each figure with its source, across 70,045 cards. Plus break-even grading math — the exact gem rate where grading starts to pay, and a plain "sell it raw" when it doesn't. Pro: free 3 days, then $9.99/month.
