Sdub, don't take this wrong, but : I say you went about it all wrong. To start discussing contracts and split methods, before you've even hunted, is the FASTEST way to get a "no" to your permission request.
To start talking negotiations, and putting contracts in front of them to sign, just conjures up legal hassles, treasure chests, blah blah.
I mean, dude, this is THEIR land. So OF COURSE the stuff on the land belongs to them.
All I ever tell them, before a hunt (
if they even ask) is : "You're welcome to anything I find." And invariably, just like CFMCT and JNimons say : It rarely ever works out in any kind of negative way.
I'll just pile everything on to my tailgate at the post-game show. And will pull a token or a seated coin I want aside next to the pile. And say : "Here's one I don't have in my collection, can I have this one ?" And will push the rest of the pile bulk towards them (wheaties, common silver, etc.....). And I have NEVER had anyone say "no, give it all to me".
Yes, on the extremely rare occasion that I have had to fork over everything , these were cases where I was hunting obvious historic landmarks. Where the stuff in in museums now. So pictures are just-as-good in my book. The thrill of the hunt is a prize in my book.
And when you think of it, this hobby is about 99% show & tell anyhow (none of us are "getting rich" by this). So to show & tell, all ya need is pictures, right ? You still have your boasting rights, eh ? Presto, that's 99% of the hobby in the first place.
