Munzenhandlung Erwin Dietrich Ag

What Munzenhandlung Erwin Dietrich Ag does

Erwin Dietrich AG is a privately held, single-location numismatics and precious-metals dealer headquartered at Werdmühleplatz 4 in Zürich, Switzerland, operating continuously since 1957 under the trade name numismatik.ch. The business buys and sells collectible coins and banknotes (Swiss, European, American, Asian, African, and Middle Eastern), commemorative and shooting medals (including Schützenbecher and Schützentaler), non-valeurs, diamonds, jewelry and old gold, silverware, and investment-grade bullion in gold, silver, platinum, and palladium. Inventory is drawn from international refineries such as Aureus, Valcambi, Metalor, Degussa, Geiger, and PAMP for small collector bars and plates. The firm holds the Swiss BAZG Registrierter Altgoldankäufer certification authorizing purchase of precious metals from the public, and is a member of the Verband Schweizer Berufsnumismatiker (VSBN) and the Berufsverband des Deutschen Münzenfachhandels (BDM).

The underlying technology stack is a conventional e-commerce build: a product catalog at numismatik.ch spanning multiple geographic and historical categories, an in-house Edelmetallrechner (precious-metals calculator) that values gold, silver, platinum, and palladium items against the day's spot, and a live Kitco gold/silver/platinum price feed embedded directly on the homepage. A separate online auction channel runs on dietrich.auex.de (partnered with Sincona AG), enabling periodic auction events for coins, medals, and collectibles, with a CHF 50 minimum order for deliveries. Distribution is dual-track: a physical Zürich storefront with retail hours and a global e-commerce/auction storefront accessible online.

Revenue is generated entirely through transactional spreads and markups — buy/sell spreads on bullion, markup over intrinsic and numismatic value on collectible coins, banknotes and medals, acquisition pricing on old gold, dental gold, jewelry and silverware, "price on application" sales of diamonds, and buyer premiums on online auctions. Customer segments are collectors (numismatists and banknote collectors, Swiss and international), precious-metals investors (buying and selling bullion), and — to a lesser extent — the jewelry and dental industry selling scrap precious-metal materials. The firm is recommended by Swiss banks, savings banks (Sparkassen), and Swiss television (SF DRS), indicating established third-party trust signals. With only 1–10 employees and no disclosed institutional ownership or external funding, the company operates as an independent, founder-named Swiss specialty retailer.
