Well, my collection is smaller than a lot of yours so it is easier for me to have "singles" since just about anything except the most common beads on a mixed strand are unique to me. The first one I found on a mixed strand at Tucson this year. I know Thomas has a whole strand of these but I still think it is pretty cool. I wish I knew why these were made though! The second is a Roman bead that I got from Bassam may years ago.

OK, I don't know why the first image didn't post!?
