How to Write Auction Lot Descriptions (With Examples)

Why the description does the selling

On most auction platforms, a bidder never holds the item. The photos and the description are all they have. A vague description ("old vase, good condition") creates doubt, and doubt lowers bids. A specific, honest description builds confidence, and confidence raises hammer prices. Writing good lot descriptions is one of the highest-leverage things you can do, and it follows a repeatable structure.

The anatomy of a strong lot description

A good auction lot description usually has five parts:

1. What it is. Lead with the object and its most identifying facts: type, maker, pattern, model, or artist.
2. Key details. Materials, dimensions, age or period, markings, signatures, and anything that establishes authenticity.
3. Condition. Be specific and honest. Note wear, chips, repairs, or losses. Bidders trust sellers who disclose flaws.
4. Context or provenance. Where it came from, what it was used for, or why it matters. This is what turns an object into a story.
5. A clean close. Keep it factual. Avoid hype words like "rare" or "must-have" unless you can back them up.

Example: before and after

Before: "Vintage blue vase, nice piece, some age."

After: "Roseville Pottery Wisteria vase, circa 1933, in the blue glaze. Stamped on the base. Stands 8 inches tall. Excellent condition with one small glaze nick to the rim, shown in photos. From a single-owner Ohio estate."

The second version answers the questions a serious bidder would ask, and it discloses the flaw instead of hiding it. That honesty is what protects your reputation across sales.

A template you can reuse

Use this fill-in-the-blank structure for any lot:

• [Object], [maker or artist], [period or year].
• [Material], [dimensions], [markings or signature].
• Condition: [honest condition notes, reference the photos].
• [Provenance or context, if known].

Writing 200 of these is the hard part

The structure is simple. The problem is volume. Writing a thoughtful description for every lot in a 200-lot sale, by hand, is days of work, which is why so many catalogs end up with one-line descriptions that leave money on the table.

This is exactly what AI cataloging solves. With Estimint's auction description generator, you photograph the lot and the AI writes a structured description, condition note, tags, and a value estimate using multi-image analysis that reads every angle. You review and tweak instead of writing from a blank box, so every lot gets a full description, not just the headline pieces.
