1 Pfennig Ferdinand I 1522 - what mint? [Risolto]

Hello, I got into my collection 1 pfennig Ferdinand 1 1522. Year is clearly visible and readable. However, other parts of coin are heavily worn, but it seems to me, that there is only 1 shield, not 2 as on pfennig from Graz (https://en.numista.com/catalogue/pieces77740.html) or Linz (https://en.numista.com/catalogue/pieces71674.html).
Moreover, I found in one shop two examples of such coin type, but without any further information:

https://www.ma-shops.com/macho/item.php?id=3103

Reverse is uniface. Diameter of coin is 14,5mm (could be slightly larger in original version).
Could You help me please?
Thanks,
Palci
