A detectorist has asked on a forum whether there are rules for sharing finds with farmers and been told “There isn’t no hard and fast rules“.
However, in the rational, well-behaved world inhabited by ramblers, amateur archaeologists and everyone else, there IS a hard and fast rule.The finds should be handed to the farmer as they are his. How hard is that to understand? The farmer can then get independent advice on their significance and value and then, only then, he can decide if he wants to reward the finder.
Any other arrangement is a blatantly unfair contract for it puts the detectorist at an unfair advantage in which he alone knows the value of the finds. Only an oik or a crook would do that yet that “no hard and fast rules” situation is supported by both the National Council for Metal Detecting and the Portable Antiquities Scheme by omitting to explain and to specify a fair contract. (The NCMD do it because detectorists want it that way and PAS do it for the same reason. But PAS are supposed to be respectable! What’s happening?)
