So I know this thread is long dead, but it’s full of very good info. I was wondering if anyone could help me with some history.
I spotted this miniature badge on EBay (which has sold, unfortunately) and I was very curious as to it’s history.

I’d never seen miniature badges other than a stray mini Kappa key that isn’t a standard badge, rather more of an accessory I think. Did Kappa Delta have mini pins? Are they indicative of anything in particular? The badge has initials and chapter engraved on the back, along with a badge number. Not sure if that info is able to be looked up by any KDs? I had heard that miniature badges were stylish for a while, but what time period was that? Badge history fascinates me!
