I am in a similar situation, except, the landowner doesn't know it yet. A man I worked with used to work as a teenager on a large farm to help an old man during the summer. He and his wife passed away, and only had one daughter, who lived over 300 miles away. His daughter would come in every couple of weeks and try to find the treasure her father had buried. She had hired several people with detectors to locate it for a fee, but they were not able to find it. One day while I was in the neighborhood, I stopped long enough to survey the land and do a little investigation. This was not and still is not posted property. She had since sold the property to a realitor and he has started building 4 homes on the property. I haven't approached him yet, and don't know if I will or not. The treasure is a 10 gallon ceramic churn full of silver dollars. Her father farmed for a living, but also worked for a company and was paid in silver dollars. Her never spent any of the silver dollars and also when he sold cattle, tobacco or hay, he also got silver dollars. His daughter told my friend that she remembered him wheelbarrowing the hoard out one night and never returned with it. I am relatively sure I know where it is buried. or in a real close proximity. Also I am relatively sure if I offered a split with the realitor and the daughter found out, we could both lose it in a court battle. I have been sitting on this for about five years now, and the daughter is getting way up there in years, so I may hold off for a while longer. I have offered others a 50/50 split and they have taken the deal. Still, I know of others that were offered the deal and were told to leave and not be caught there again. Each person you deal with can have a different perspective on such a sudden probability of wealth. Good Luck with yours, rockhound
