Auktionshaus Ulrich Felzmann GmbH & Co. KG

What Auktionshaus Ulrich Felzmann GmbH & Co. KG does

Auktionshaus Ulrich Felzmann GmbH & Co. KG is a privately held German auction house founded in 1976 and headquartered in Neuss, North Rhine-Westphalia, operating as a GmbH & Co. KG within The Founders Auction Group. The firm specializes in philatelic (stamp) auctions with adjacent categories spanning numismatics (coins, medals, banknotes), autographs, postcards, and militaria. It is positioned as one of Germany's leading philatelic auction houses, with particular recognition for air mail and Zeppelin mail expertise, and serves an international collector base across Germany, Austria, Switzerland, the UK, and the US.

The company runs a multi-format auction operation combining traditional live salon auctions (Saalauktionen) at its Neuss premises with a proprietary online auction platform (e@uction at auktionen.felzmann.de) supporting real-time bidding. The annual calendar comprises approximately three live auctions and three e@uctions, supplemented by special themed sales (for example the Rhenumis numismatic series). Underlying technology includes the proprietary bidding platform, a WordPress-based marketing website, Yumpu-powered digital catalogs, WhatsApp-driven preliminary valuation with philatelist Axel Möller, and home/on-site consultation services. Authentication leverages human expertise referencing the Michel catalog and recognized bodies such as BPP and PTS.

Felzmann generates revenue primarily through transactional commissions: a buyer's premium (Aufgeld) of 26.2% for EU consumers and 22% for EU traders and third-country buyers, plus €3 lot fees, alongside consignor commissions deducted from hammer prices. Consignments are sourced through free valuation services, trade fair presence (Briefmarkenmessen, World Money Fair, Boston World Expo 2026), and the WhatsApp consultation channel. Customer segments include private collectors and estate inheritors, hobbyist philatelists, dealers and traders, and estate executors, with bilingual German/English servicing supporting cross-border participation. Notable outcomes include a €260,000 record for a Dassier 10 Rubel 1757 coin and a €135,000 record for an Audrey Hepburn commemorative stamp.

Direct peers
