My friend's dumpster dive find full of stick pins.

My friend found a bag filled with all these pins behind a local thrift store about 10 years ago. I have had very little luck finding out anything about them beginning with what to actually call them. They appear to be, for the most part logo's in another language or sorority titles with some familiar such as red cross pins and a lot of plain figures as well (man with beard etc.) This is displayed in his kitchen and makes a wonderful conversation piece.
