Assuming you find a meteorite. You want to be 100% sure and give it, or a piece of it, to a geological institute for investigation. They find out it's really a meteorite. As you found it and it would probably be lost to humanity if you didn't take it with you and made the effort to have it analysed, you clearly deserve something. Do they give you the meteorite back after you pay for the analysis or do they keep it? Or do they even claim the other pieces which you didn't hand in for analysis?
How is finding a meteorite handled and do you even have a chance of owning/keeping one that is found to be a real meteorite - after all, you have to get it analysed if you want to be sure?
