Use this for a signed item you are considering buying, selling, or adding to your collection. Describe the signer, item, chain of ownership, and certificate wording to spot gaps in the provenance and assess what the certificate does—and does not—say. Compare two item descriptions or prepare focused questions for the seller or authenticator. Leave with a provenance summary, comparison, or question list.

Ways to start
A few requests this Agent can handle.
I’m considering a Mickey Mantle-signed baseball from a local seller. The certificate says JSA, but I have no ownership history. What questions should I ask?
A seller offers a signed Taylor Swift tour poster with a certificate from a small shop. The wording says “authentic signature.” What does that establish?
Compare these descriptions: a Babe Ruth-signed photo with a named auction-house provenance, and one with only a seller certificate. I’m buying for my collection.
