Hello guys, I was just wondering what's this badge. Rare?







The seller is asking for US$ 1.600.. ¿is it worth that much?

Thanks in advance!

Hello Sepp,

it is Austro-Hungarian (Kaiser Karl) badge for observers and balloon crews:

How much it is worth? I don't know, lets wait what others will say.
