If you told the current property owners that there might be some coins buried, they likely would assume you were going to dig holes all over the place and say NO! Tell property owners exactly what is buried and how you intend to recover the jars, then offer a split. If they say no, no loss since they do not know where the jars are buried.
I am guessing that a quart jar full of silver coins could be 5 to 10 pounds. That could be $1700 to $3500 per jar?
I remember in at a very young age before we moved to Tennessee, that on certain weekend days, he would have me help him sort out silver dimes from quarters, etc..I would have been maybe 9 or 10? My hands would be black from the soot off of the coins.
My mom always said I would be surprised how much he buried, but I always thought that was kinda BS exaggeration on her part, but knowing my dad, it could be? He was born in 1930 and grew up with nothing during the great depression and had to wear his older sister's dresses as clothing.
A lot to think about, but I need some kind of resolution.
