Welcome to the site Francesco.. Your bold in even giving your first name, I hide my name like I do the secret of building the pyramids.
Now you mention historical researcher.. I guess all of your finds would go to a museum of some sort. I have a great deal for you then. Do some research on "Lost American Treasures", when you find something good I'll split it 40/60. I'll be glad to give you an extra 20% so I don't have to do any research
