Ancient Chert Stone Tools

I am looking to gather information and potentially sell: Seven (7) Ancient Stone Tools I purchased these tools from an estate sale of a private collection about 15 years ago. There was very little information given on them as much of the larger collection was undocumented, but I can provide what I know and would love to learn more. The information I have from speaking with experts is mixed, some suggesting lower paleolithic while others mastodon era. They are a mix of choppers and flake tools, and someone noted they could be European or Iberian. I have some information on the original owner but not much. I can provide this if you are interested. You can see additional photos if you follow the link below. Thanks!
