Hi All, I find old and vintage items from another era to be interesting. Do you have any old items you keep?

The item I pictured below is an ashtray from the Biltmore hotel and is marked 1925. I think it's silver. There are a few carvings on the bottom. Most notable says "Mu Sigma Convention December 25, 1929." The Mu Sigma is in greek letters.
