SilphCo ingests completed sales from eBay, TCGplayer, Mercari JP, Fanatics, and physical-card-backed on-chain marketplaces — then reconciles them into a single market view. Here is one card's raw Near Mint market, sale by sale — every dot a real settlement.
Every price is a 30-day volume-weighted average of real completed sales, computed per card, per grade, per language. No listing prices, no wishful asks — settlement only.
From Base Set to this quarter's releases — every set gets the same treatment: daily volume, sale counts, average price, and PSA 10 share. Small multiples, same scale question, no chartjunk.
Physical cards now settle on-chain too. SilphCo indexes vaulted-card marketplaces on Solana, Base, and BSC alongside the traditional venues, and resolves every sale back to the same card identity.
Every chart above is rendered from real responses of the public SilphCo API — versioned contracts, a SQL-over-HTTP endpoint, and an agent that answers in charts. Free keys at silphcoanalytics.xyz/dashboard.
