I don't know where Pablo dug up all his finds but if it's just farmland then I wouldn't call it "looting". If it was known archaeological sites then I would. If the cops raided my finds it would look very similar (if they emptied them out of their numbered bags onto a piece of tarpaulin). I also own 3 metal detectors.
Wonder if they had permission? We used to visit Lochindorb, you could hire a boat and row to the island with a ruined castle. Would give that a search but probably covered in modern junk from all the visitors.
You need permission in Scotland or at Loch Lomond? Folk going past in boats all shouting at them I.e can you find my keys , if you find 3 quid it’s mine etc
You need permission from the landowner. Only place you don't need permission from the landowner is the area on most beaches between high tide and low tide. Most beaches are owned by The Crown Estate who allow metal detecting on the foreshore without the need to obtain permission.
I have very few finds to register from last two years and haven't done any metal detecting this year. Crops are coming off about now so ought to get out there.
Was it common behaviour for them to bury their wealth back then? I know that during the Great Fire of London it was common behaviour for the wealthy to bury their cheeses to protect them because the cheeses were more valuable than coin. Asking for Aldo 2.0 (Aldo 1.0 isn't interested)
Before the advent of high street banks, that's what people did with their wealth. In times of war, especially so. Some of the huge ancient hoards with tens of thousands of coins, it's likely that was the community's "bank".
