this is a very nice Indian arrow head colection . t is 30 arrow heads from Trumbull Co. , i do not know what state . i do not know what year these are but they are old . all in real nise shape and some of them are very nice looking . not sure the types of stones that were used . some of these might not be arrow heads , they might be other tools like knives , speer heads , ect. t are some black , opaque , gray , white , and other colors . all very nice . this is my small collection . t will be a bigger one in the next auction .
