Your collection, on your shelf.
Every lot you've ever owned, valued at the same fair-market price the marketplace runs on. Cost basis, P/L, set completion, daily movers — all in your binder. Free for collectors.
What the binder shows →Track every card you own, buy and sell with a 0% platform fee, and price against numbers that show their receipts. The whole hobby, one app.
Search routes into the live catalog spine and marketplace context, not a static marketing mock.
Search Charizard →Seller pricing is subscription-funded; public marketplace paths do not add a platform rake.
Compare plans →Published values carry method, sample size, confidence, source context, and honest insufficient states.
Open methodology →Storefront and seller discovery are live; depth grows from real sellers instead of seeded claims.
View stores →Every lot you've ever owned, valued at the same fair-market price the marketplace runs on. Cost basis, P/L, set completion, daily movers — all in your binder. Free for collectors.
What the binder shows →Buy any card from any seller; list any card to any buyer. The number above the buy button is the same fair value our portfolio uses, so seller and buyer see the same truth. No bidding-war hidden fees, no quiet rake.
See live listings →Trimmed median over 30 days, 95% confidence interval, sample size, last-sale timestamp, attribution. A daily watchdog flags drift against external comparables. Public methodology. Public API. One-line embed.
Read the methodology →Marketplaces, insurance carriers, and portfolio apps cite VaultStore prices because every response carries a version, a confidence tier, a sample size, a methodology URL, and an honest insufficienttier when we don’t know.
