Bremen 1764-RDDB groten KM-228
The first specimen was lot 1144 in Stephen Album sale 32 (Santa Rosa, CA, September 2018), where it sold for $105.75. The catalog description[1] noted, "BREMEN: AR groten, 1764, mintmaster RDDB, PCGS graded MS64, ex Don Erickson Collection." This port on the North Sea was in decline in the eighteenth century, as reflected in its scanty coinage. It revived after the Napoleonic Wars as Germany began to industrialize. One thaler was 72 groten. This type also comes as a klippe (KM 204) but is rare thus. The second specimen was lot 1509 in Künker Auction 425 (Osnabrück, July 2025), where it sold for €1,100 (about US$1,558 including buyers' fees). The catalog description[1] noted,
