None of the points in this picture are old. They were made by modern flintknappers and there's no problem if they were collected as art. They become "ghost points" when they're purchased with no evidential information that might support the value placed on them. In-other-words the buyer thinks they're old. They are usually higher priced items that only have a good story. Since the beginning of the great flintknapping boom in the United States, in the 1970's, there are more "ghost points" in circulation that old ones. They number in the millions. Some even have authentic patina, for example, if they've been place in running water for a few months.
