Nice coin and nice history!
I do not (yet) have any bracteates to post, but would like to build on the thread with the following. Kempten in Bavaria is a place which has had a strong cult of Saint Hildegard since shortly after her death in 1179. Hildegard founded female religious communities at Rupertsberg and Eibingen, in the Palatinate, but I don't think either of these minted coins. There are, however, bracteates from the Kempten Abbey dating to the beginning of the 13th century which bear her image. I'm not sure I have run across an earlier representation of a post-biblical female saint on a coin.
I have posted this much later coin from Kempten city bearing her image on the German States thread (it's dated a bit too late for the ancients and medieval thread, but ...):
