Here’s a nice Gold Grade Wound Badge in zinc. As with many zinc based badges, this one no longer shows any of the original gold wash, with the exception of the pin on the reverse. Since the pin is not zinc, the gold wash remains.
The maker on this badge is “30” (shown on the reverse of the wound badge), which can be attributed to the Hauptmunzamt of Vienna firm.
The original case shows normal shelf wear with the paper hinge having worn over the years from being opened and closed. These paper hinges were never meant to last, but thankfully the hinge alone does not attach the lid to the base. You can still open and close the lid just fine thanks to the piece of white fabric on the interior, which acts as a secondary hinge.
On the bottom of the case is the blue manufacturer sticker labelled, “Hauptmünzamt Wien III.”
