Our Auctioneers

Since 1913 the name of Heinrich Koehler has stood for outstanding auctions in the philatelic world. Such a reputation cannot simply be acquired or assumed; every day it encourages and demands new achievements. At Heinrich Koehler we are aware of this long tradition, and we gladly accept the challenge of its continuance. Not only this - it has become an integral part of our business culture.

The first Corinphila stamp auction took place in 1925 in Zurich under the name of the founding family of Eduard Luder-Edelmann.

Caspary and Alfred F. Lichtenstein. Now in our ninth decade, we are more committed than ever to providing our customers with the professional service and philatelic expertise that have long been synonymous with the Harmer name.

The Romano House of Stamps was founded in 1994 by Moshe and Mira Romano.

Mira, formerly an attorney, has been vital in all the day-to-day operations of a growing company. Their daughter Sharon joined the firm in 2001 to assist in expanding the auction, especially to collectors overseas. The family's efforts have been a success. They have become a unique source in the Holyland for collectors everywhere.
