Gemini CLIAbout this skill
Verify that an object is what the seller claims and that its chain of ownership corroborates the attribution. Use when buying any high-value collectible, when an item's history has gaps, when forensic analysis is being considered, when a Certificate of Authenticity is in hand (or conspicuously missing), or when a piece's provenance is being assembled for sale, donation, or insurance. Authentication is the foundation that grading and pricing both sit on top of — skip it and the rest of the analysis becomes decoration.
