Late comer here and my 1st post after making a year on this forum.
Here is my Coburg badge stick pin and my type 2 Coburg badge with RZM.
On the other forum Erich mention I think there was listed about 50-60 known badges in collections as members there posted their badges.
What's strange is the type 1 outnumbered the type 2 as the type 1 had 34 in known collections and the type 2 if memory is correct 23, so on both type 1 and type 2 badges totaling 57 badges.
Its obvious the number could be higher as many collectors are not on forums but the impression I have the Coburg badge is a rare award.
