A stamp, signature, label, or other identifying mark on an item indicating its manufacturer, designer, or artist. Maker's marks are found on pottery, porcelain, silver, furniture, fine art, and other antiques. Identifying the mark is often the single most important step in accurate lot description and valuation.
How It Works in Practice
Maker's marks are typically on the bottom (pottery, porcelain, silver), back (paintings, furniture), or inside (jewelry, watches). This is why detail shots and multi-photo AI analysis are critical — a front-only photo never captures the backstamp that distinguishes a $50 vase from a $5,000 one. Reference resources like Kovel's marks guide, Replacements.com, and online maker's mark databases help auctioneers identify marks. AI cataloging tools with multi-photo analysis can read and identify many common marks automatically.
