I have to say, this has been one of the most interesting subjects, with lots of opinions, and I'm sure lots of people are following this.
Dont let us down Frankn, keep us posted till you reach the conclusion. There are a lot of lessons here, on what to do and not to do, but we wont know until the end, which was the right way to go.
Maybe we could even start another thread, on the question of agreements between "Treasure" hunters, and land owners, (not about permission to search a yard for a few coins)
Also how to make an agreement between a treasure hunter and his partner(s). What happens after long hours of research, and one partner goes it alone, and uses the research to find the treasure. As Frankn pointed out, some projects are just to big, to do it alone, some are impossible. There are probably more than a few of us, that have some kind of lead to a possible treasure, but cannot do it alone, either because of financing, time or know-how. So what is the best way to move forward, or do we just say, "its too big", and give it up?
Another question is actually who OWN's the treasure, its not always an easy question, as Odessy found out. Most treasures are owned by someone, the bank, insurance company or the person the money was stolen from, although most here believe that once its buried, we can just go dig it up, so how do we go about getting ownership, Before we spend time looking for it? And before you say, "just dig it up and be quiet about it, just sell a little bit at a time". Think it through, its not easy to sell old coins, bullion or whatever, without leaving a trail. Do you want to exchange your metal detecting hobby into a criminal occupation?
Hope we can get a good, interesting discussing going.
