I was looking on ebay and saw this pin advertised:
http://cgi.ebay.com/Vintage-14kGOLD-...QQcmdZViewItem
It says it's "Alpha Phi Omega" but looking at the shaft of the key, I see KKG big time. I know someone would like to get this off eBay , I know my daughter's sorority keeps a lookout for their pins on eBay in order to return to the original owner, if stolen, or to offer members as a replacement badge. This one is dated 1930 and could even be part of any museum you may have. It's beautiful and shouldn't be on eBay!
