Friends:
The proofs are obviously German, post 1892. As for the big crowns, any official mark using a "crown" as a tax stamp, etc., most likely went the way of the monarchy.
Notice how the crowns are decidedly different in their conformation. Perhaps one is the imperial crown and the other the Prussian state crown.
Just speculation.
