That's a great pin of Beta Pi Delta. I saw one on ebay and it did not look as nice. I do know that the Toronto chapter of BPiD went to AGD b/c they wanted to be part of a more established sorority.
Is it me or is the Pi Phi using the lower case pi/ the pi we always see in math class, with an upper case Phi. Was the sorority name spelled "pi Phi" or "Pi Phi"?
