This badge looks so odd - it's a 1991 model? I mean, it doesn't look antique per se, but it doesn't look like a modern badge either.
So, the other day I was browsing ebay when I saw a Gamma Phi Beta antique steel engraving for sale. I've cropped the picture and posted it here. I notice the striking similarities between the engraving and the badge for sale. The engraving is from 1908. Maybe this 1991 owner had an antique badge re-engraved with her info? Or maybe it was some kind of special anniversary edition? Hrm...yet, the monogram doesn't seem to match the crescent underneath - are they two different piece put together? "...the badge is just unique" doesn't satisfy my curiosity.
SmartBlondeGPhB, since you seem to know the owner, maybe you or sacvatire could find out for us? Also, the auction winner appears to be a sister - was the badge returned to her owner?
