New to me Akro Agate pieces

I was invited to the Akro Agate collectors auction in WV last weekend. Had a GR8 time hanging with the locals! Managed to find a couple goodies for the collection also! Top left marble is called a double ingot, formed by two separate "globs" of glass coming in contact with each other while still molten and then continuing through the machine. Bottom left is a misshapened Lifesaver, almost marble. Marble on right is a green & blue snake. The Akro crow logo fob is a very scarce, 1 of 50 piece! Akro experts don't know it's exact purpose but all agree these are very hard to find and great Akro related pieces. GR8 weekend!!!
