IBRA 2023

Heinrich Köhler is official auctioneer, sponsor and philatelic partner of IBRA 2023.

From 25 to 28 May 2023, the International Stamp Exhibition in the Ruhr metropolis of Essen will open its doors to collectors from all over the world. IBRA 2023 is the world championship of philately, at which many exhibitors from all over the world will present their outstanding exhibits. The last comparable exhibition on German soil took place in Nuremberg in 1999. Only every 25 years or so does Germany have the opportunity to experience a philatelic exhibition at this high level. So there is no question that Heinrich Köhler is supporting IBRA 2023 as one of the main sponsors.

In addition, Germany's oldest stamp auction house will present the reading room as well as the Forum Philately – Presented by the Consilium Philatelicum. Don't miss this extraordinary philatelic festival. Among other things, exciting special shows and a treasure chamber with ultimate philatelic world rarities will attract visitors.

We also recommend that you pay special attention to the IBRA special auction, where smaller and larger rarities starting from the foundation of the German Empire from the ERIVAN collection will be offered for sale. We look forward to seeing you at our stand at IBRA 2023, where you can test our new innovative Provenance Finder, among other things.
