Judenburg:
In the 14th century the first gold coins after ancient times weres struck within the borders of modern day Austria. They were struck in Judenburg, a town along a trade route back then. The dukes of Styria Albrecht II. and later also Rudolf IV. struck imitations of the Florin of Florence.
The Florin of Albrecht II. is already in the numista catalogue but not under the Judenburg mint because it doesn't exist yet. The Rudolf IV. Florin does also not exist yet. These are the only two coins ever struck in Judenburg.
Oberzeiring:
Oberzeiring is the oldest and most important Styrian silver mine. Records weren't kept well and when Francis I. (II.) requested to get a full history of the silver mine in the early 19th century historians found out that it was simply lost, probably burnt down in a fire. However we do know it was first mentioned in the 10th century and was very rich in silver (there is still a bit of silver there today).
Originally the silver was all transported to Graz to mint coins there and it is one of the main reasons for the wealth of the city of Graz in medieval times. However coins were also struck directly in Oberzeiring, not a lot is known about them and there are only a few confirmed coins because as said before, records were either not kept or lost.
Fun fact: the name “zeiring" has the same celtic origin as the name of the swiss city “Zürich”. Meaning “somewhere with at a body of water”.
If you want a soruce for my information: the Judenburg one is basically common knowledge and I have no idea where I would find that and for the Oberzeiring one I have read the book about the known history about it.
