One of the classic Mosser Collie colors is Crystal, aka Clear. The early Crystal collies glow faintly green under an ultraviolet light (“black light”), suggesting the presence of some uranium in the mix. However later crystal collies do not fluoresce.
In the early 2000’s, Mosser was selling collie figurines in several variations in addition to the basic clear version. Pictured below (L-R): Crystal Opal, Crystal, Crystal Carnival, Crystal Opal Satin. Not pictured, Crystal Opal Carnival and Crystal Satin.
