Antique 1878 14k gold Psi Upsilon fraternity pin badge.   Guaranteed to be 14k gold.  Measures 5/8" by 1".   Pin is in pretty good condition, but the clasp has been replaced at some point (repairable with a good jeweler).  Marked on the back '78, Beta, AA Dershimen, & s.y.d.    I don't clean items I leave the original Patina on it. I have other collectibles in my eBay store and feel free to take a look.  Once again thanks for taking a look.
