NO. Stupid to melt it down OR turn it in, since Britain only pays the “market rate” for finds. Ridiculous. Best to take your time and find a dealer who sells such items to collectors in the black market. Could easily get $25,000 for an item like this, whereas “market value” even if 24k gold would be less than $2k.
But you would have to start some relationships with “interesting” people.
Metal detecting and guns.
Best to know the rules before hand.
I suppose a whole bunch of other things too. Especially in England what with driving on the left side of the road and all.
It's clear that you don't understand the difference between "market value" and "melt value". Great Britain has the most fair and sensible metal detecting laws (Portable Antiquities Scheme ) in Europe.
