Gabnn3, it depends on who you're asking this question to. I suppose if you asked enough lawyers, and tax-collector people, you would get one answer. Heck, I suppose if we md'rs "asked enough questions of enough lawyers", and if we md'rs "desired to be totally technically accurate to every last law", we'd probably all give up our hobby right now.
Not that I'm advocating "breaking laws", but just saying, it's an endless slope. Examples: You're supposed to call the utility Co before doing any digging. Those "call before you dig" 800#'s, so you don't hit a utility line. Did you do that ? And then you'd also have to turn in the items to police lost & found (afterall, there's no age/time criteria in all 50 state's "lost & found" laws). And then sure, the age-old taxes question: Not only do you with your cache of gold have to worry, but every last one of us who finds even-only clad, must dutifully report the income on our tax returns. And schemes like you're thinking of (to transfer state-to-state to circumvent), would probably fall afoul of some forbiddance of "evasion" or "subterfuge", etc....
So a part of me has no doubt that if you found loads of gold on your land, you could probably find some tax collector to say you owe taxes on it, EVEN IF YOU DIDN'T SELL IT (yup, someone one time posted that it's not reliant on selling your finds, if you can believe that).
I realize that cuda-mark and I didn't answer your question, but .... just saying you may not like the technical answer.
