In the summer of 2017 a volunteer archaeologist investigating a field in Brandenburg unearthed a special find. This discovery was followed by a systematic investigation by archaeologists from the Brandenburg State Heritage Management and Archaeological State Museum (BLDAM) which continued until 2018 recovering a total of 41 “plain rainbow cup coins” (glatte Regenbogenschüsselchen). This is the largest Celtic gold find in Brandenburg and the second largest ever hoard find of plain rainbow cups of Kellner V A, in an extremely rare association with full and quarter staters of V A type recorded outside the normal distribution area of rainbow cups in general and plain rainbow cups in particular. In addition to die studies, metal analyses were carried out which, despite the lack of motifs, could also allow unexpected conclusions to be drawn about the coins. New and partly unpublished results will be presented.
