A few weeks ago the IBRA 2023 website mentioned that thanks to Richard Borek GmbH & Co. KG, the unique Bordeaux Cover bearing both one penny orange-red and two pence deep blue Mauritius examples will be on display at the IBRA Schatzkammer during the exhibition.
On 9th January, a post in the news section of the website reported that Auktionshaus Heinrich Köhler revealed that the three most valuable rarities of German philately will also be on display:
- the only known first day cover of the “Black One”, the Bavarian 1 Kr. stamp of 1 November 1849,
- the legendary “Baden misprint” 9 Kr. on cover, which was printed on green instead of pink paper (only one other letter and one piece of cover are known of this one) and
- the only complete sheet of the “Saxony Three”, Germany’s second stamp, still in existence.
As we are closing in to the exhibition, more announcements are expected on rarities that will be included at the IBRA Schatzkammer.
