Hello -
I too am saddned by the loss of these pins to collectors...The XO pins in question went to a man who has a great deal of money and VERY FEW people can outbid him. And when they try they end up paying a 4 figure price tag. This bidder isn't a graceful winner or loser as I came to find out after bidding on a lazy phi pin...There isn't much that can be done as they are from estates and up free free sale on the open market...
What needs to be done is education to ALL sororoity and fraternity members that in case of their demise, that the pins go back to the chapters, EO's or a family memeber who will know what to do with them.
Good luck on trying to get them. Here's to all greeks - we are sisters regardless!
