I haven't been able to identify the provenance of the coat of arms emblazoned on these buttons.
These metal buttons have an antiqued brass look. The brass is a bit weathered, especially on the back--on one, you can see where the metal has turned green. My guess is that it was stored with an early plastic button that didn't quite agree with it.
I make use of recycled packing and shipping materials, both to be eco-friendly and to minimize shipping costs. So don't worry--it might have come to you in an old television box, but your item was packed with care to arrive safely on your doorstep.
