Moss says that it's a committee that decides the going rate and Mark says that they are valued according to what a museum would pay for them as opposed to what a private collector would pay for them. Fair enough, but fair play has me wondering if the 2 gents in question in the article would donate their 'reward' to some conservation charity or summat similar. I guess it comes down to the way you look at things – bronze axe heads as an economic resource or bronze axe heads as a cultural resource.

Thanks to everybody who responded and sorry if this topic has been done to death before.
