3 Spear points of Unknown Origin

The 3 spear points come from an unknown location and time period. I am leaving this up to you guys who know better than I. My only experience with handcrafted points goes only as far as arrow heads from the east coast. The gray one is 3 inches long by 1.5 inches wide. The one to the right of the gray one is 2.5 inches long by 2 inches wide, and the lightest color one measures 2 inches long by 1.5 inches long. Nice to add to a collection and research.
