All silver made whistles. Some with hallmarks, some without. Probably the most variety lies with the silversmiths and their creativity — which is limitless !! We have left out teethers and rattles for another catagory for the future, mostly made by silversmiths. Just too many and silver raises the price somewhat heavier than we can handle with our other catagories of collecting. Suffice it to say that it is a very large category and we probably won't be able to do it justice.
