My great grandmother gave me this item, it was her fathers who was a member of the ku klux klan, I myself am a Hispanic American so it is not really an item of my interest to keep I know there are collectors out though who may serve better use to such an item so I was trying to see how much it could potentially be worth if anything. The top part appears to look like a night looks like it could be hung like a necklace and the circular part has markings when the circular part is spun fast it creates a little mirage image of a cross surrounded by the three K's from the markings on each side.

It is a type of metal I would say it was made from not entirely sure
1915 when the 2nd ku klux Klan took place
Size and dimensions of this item:
About an inch long and it's no thicker than a penny
Not sure what exactly the pendant was for but came from the early 1900's when the clan came out
