I have bad news for you. There are more names that define the Meissen groschen:
-schwertgroschen
-schockgroschen
-judenkopfgroschen
-kreuzgroschen
-meissener groschen
-thüringer groschen
-wilhelmer
-landsberger groschen
-horngroschen
-spitzgroschen
and probably different. The German language offers a wide range of specific names. There are many, many reigns of pennies. Everything is clear to the German numismatist. It will quickly find the right variety. For me, GROSSVS is groschen. I'm sorry I didn't dispel your doubts.
