You sell artifacts you find in the area

When you where a child and you would stay the weekend at Lake Crump with your grandfather you would sometimes find curious old artifacts your grandad said where pushed up from the volcano there. Little statuettes and such. You have one that looked like a snake with several heads and bat wings that was really cool. So start searching for more of these items. According to what you have researched back when you had a computer, these artifacts are from a pre-human civilization that lived around the volcano when it was still active. A blue skinned cat eyed people who where nearly extinct when the native Americans crossed over into north America. The native Americans bred out the last of this ancient race. Science and the government refuses to admit there ever was such a race, but selling such artifacts is illegal. You do it all the same. But you have to claim they are merely Native American artifacts or no one will believe you. A normal price for a item found is forty bucks. Then they turn around and sell the object for 400 bucks on the internet!
