| Additional information |
Jakza von Köpenick — also rendered as Jacza of Köpenick — was a Slavic prince who briefly seized the Margraviate of Brandenburg in 1157, the same year Albrecht the Bear formally consolidated his rule over the region. This coin was struck during that window of contested authority, making it one of the very few numismatic records of Jakza's claim. He was expelled not long after, and the Ascanian dynasty's grip on Brandenburg went uncontested for generations.
Bracteates of this type were struck on exceptionally thin flans, which accounts for the fragility endemic to surviving examples. Bahrf. 11 is among the rarer attributions in the series.
