If you happen to find a treasure in a cave what you do it and why

I would sell the treasure and give the money to St. Jude's.

First thing i would do is check what treasures are inside. If there is gold i would go to a re seller of gold products and cash in the gold. I would save myself $100 US dollars. The rest of the money i would spend on food for the homeless people on the street and stray animals. I would also spend some money on a nice gift for my parents.
