Silver Tone Mother and Baby Polar Bear Pendant

I purchased the mother and baby silver figure years ago. It has an opening where the mother is holding thee baby for a chain or cord. The piece has some weight but couldn’t find a sterling stamp so it’s listed as silver tone. It possibly is silver or heavily silver plated. There is a small hole in the bottom of the piece that may mean it was made by pouring in a mold, not sure. Can also be used as miniature animal decor.
