I bet he will get less of that than they say right now. I believe there are some rules over there about this type of stuff. Like the Gubment gets first dibs.
Might be wrong but I think I read about this a few months ago, not this one exactly but another treasure found in England.
Probably read it here on FR
I will second your recollection with my own memory of a recent historical find in the UK. IIRC, the Brit .gov has total say (not just first dibs) on historical artifacts. Basically “thanks for digging that up, old sod, we never would have found it without you — now begone with you...”
Under the 1996 Treasure Act, anyone who finds a group of buried coins has to declare it to the coroner within two weeks. If the coins are bought, as planned, by the Museum of Somerset, the reward will shared between Mr Crisp and the landowner.
The Secretary of State determines market value.
