Sterling bear - Baby's first teething ring

Baby's First teething ring. It's a Sterling Silver bear. It's 3 dimensional and not flat. It has some discoloration on the side in two areas, probably just needs to be polished up. It weighs: 26 grams The bear measures: 2 1/2" x 1 1/2" without the teething ring. With the ring it measures: 4 1/4" in length. It has silver balls inside to allow it to rattle. I guess it could be a key ring also.
