Hi,
this is the way British Museum collected many valuable items today and in recent years, BIG discoveries made BY METAL DETECTORS and amateur treasure hunters.
Then the british laws suit the scenario with wonderful and reasonable rules that make all win.
So the really big
go to all museums of "some" other countries where archeo-guys go hunting with camel-butt-hairs-brushes and find nothing as valuable as this stuff is.
But there's no limit to human stupidity, this confirms the fundamental rule.
Kind regards,
Max
