This button was marked on a card I bought as a German WW II Prisoner of War Button. I have found a number of these German gold pebbled buttons online, saying they were Officer buttons, but, none of them had the markings as this one does. It has a number 63, two stair step lines in a circle, and another circle wirh what appears to me to be initials RzM or R2M? Thank you for any assistance.
