KUENKER'S SUMMER AUCTION SALES 442-444

With its Summer Auction Sales 442-444, the Kénker Auction House in Osnabréck will once again present an exceptional numismatic selection of international caliber from June 23 to 26, 2026. A total of more than 2,250 lots with a combined estimate of over four million euros will go under the hammer, bringing together significant provenances, rare gold coins, and outstanding coins and medals from the Middle Ages and Modern Times.

The event kicks off on Tuesday, June 23, 2026, at 2:00 p.m. with Auction 442, "The Imperial Collection, Part 1." Up for auction are 337 numismatic treasures from the Collection of the Prussian Kings and German Emperors of the House of Hohenzollern. With an estimated value of over one million euros, the auction offers fascinating insights into the collecting and representational culture of one of Europe's most significant ruling houses.

Particularly noteworthy are the exceptional provenance, the outstanding condition of the items, and the large number of rare pieces. The collection was built up over generations by members of the House of Hohenzollern, including King Frederick William IV of Prussia and Emperor Wilhelm I.

Originally, the collection was housed in the Hohenzollern Museum at Berlin's Monbijou Palace. Toward the end of World War II, it was moved to the Berlin City Palace, subsequently taken to the Soviet Union as looted art, and returned to East Berlin in 1958. After that, it remained largely hidden from the public for decades and was kept at the Bode Museum.

After many years of negotiations with the government, an agreement was reached in 2025 regarding the future of the collection. Numerous items remain on permanent loan to German museums, while others have been transferred to the House of Hohenzollern. Selected pieces from this collection will now be offered for sale at the auction in June 2026.

The collection comprises approximately 2,000 coins and medals, many of which were acquired immediately after minting and were never in circulation. The focus is on Prussian medals from the 18th and 19th centuries in gold, silver, and bronze. The collection is complemented by Brandenburg coins and selected international coins, which offer an impressive overview of the Hohenzollerns' numismatic culture of representation.

On Wednesday, June 24, 2026, starting at 10:00 a.m., Auction 443 will feature gold coins from around the world as well as German coins dating from 1871 onward. Of particular note are numerous rarities from the Collection of Commercial Councilor Dr. Herbert Wenzel, with a focus on the Habsburg era. The 677 lots represent a total value of approximately 1.6 million euros.

The series concludes with Auctions 444 on Thursday, June 25, and Friday, June 26, 2026, both starting at 10:00 a.m. The focus is on the significant collection of Dr. Karl Ortseifen, featuring coins and medals from Mainz and Trier. The offering is complemented by coins and medals from the Middle Ages and modern times, including additional pieces from the collection of Dr. Herbert Wenzel as well as selected historical medals from the Reinhard Laufen collection. The 1,250 lots spread over two auction days also have an estimated value of approximately 1.6 million euros.

The Summer Auction Sales thus combine outstanding quality, excellent provenance, and a broad numismatic spectrum that is likely to appeal to collectors, scholars, and institutions alike.
