The piece shown is from our own stock, as photographed and as the tool returned it. Nothing is retouched after the cut.

Some inventory is not difficult to sell. It is difficult to find the time to list.

Backgrounds removed
Every piece cut out on white at 2048 square, or on black. Nothing is retouched or redrawn.
Named, not IMG_4821
A descriptive filename from the piece itself, then every photograph of that item numbered to match.
Catalog numbers found
HK, Fuld, DeWitt, Baker, Eglit, BHM. Verified, or it tells you which reference to check instead of inventing one.
Listings drafted
Title, description, item specifics and condition in words, plus a CSV ready to upload.
Priced when the market allows
Comparable sales at Deep Research when real ones exist, and a plain no when they do not.
You approve everything
Nothing leaves the tool without you reading it. It flags what it could not settle rather than guessing.

Three depths. You choose per piece.

Identify
Reads the photographs and drafts the listing. Enough on its own for dated coinage with no catalog number, which is most of a dealer's stock.
Attribute
Also searches for the catalog reference and the published size and weight. The one for a so-called dollar, a Civil War token or an exposition medal.
Deep Research
A wider search for a genuinely obscure piece, and the only level that looks for comparable sales.
