Thanks. There's a link off off the BBC story to a hoard of 20,000 (!) coins, perhaps that's the one you'd read about (2004).
Thanx for the link.It was also on the History Channel.A guy(amateur)asked the land owner if he could try out his metal detector in the field.Single coins had been turning up over the years.Talk about luck!I believe(not 100%sure)the gov claims all finds,but pays finders fair market value.
