BTW, when you bury your valuable coins, remember to bury it deep,and then, a few inches from the surface, thow in a few nails. Metal detectors will get a hit and when they dig up the nails they will think they found what was detected.
Good idea.
Ahem, regular nails won’t work with a good detector. They differentiate between ferrous and non-ferrous. If you want to do that bury the gold deep and sprinkle aluminum nails into the hole as you refill it. Lots and lots of aluminum nails.
Great idea. Now I have to go check out those old nails in the woods I left behind.
Ferrous and non-ferrous metals give off very different sigals to a metal detector, and a skilled operator can discern that quickly. After the nails are removed, there’ll still be a noticeable non-ferrous signal.
