Found a Roman coin in a field near Bath that was plowed for 40 years and never turned up a thing until now
Went out with a metal detector to a farm field outside Bath that a farmer has plowed every season since 1983. He switched to a no-till drill last fall and this spring I pulled a silver denarius of Hadrian from about 4 inches down. Turns out churning the soil was breaking coins apart and scattering the signal, so less digging actually gave me better finds. Has anyone else seen no-till fields change what they pull up?
40 years of plowing is a lot of damage when you think about it. I hunt a hay field near Cirencester that got switched to no-till about six years back and the difference showed up fast. The first season after they stopped, I pulled three Roman bronzes out of one strip that had given me nothing but junk before. My guess is the same as yours, the plow was dragging coins around and busting the weaker ones into pieces too small to hit clean. Now the stuff sits where it fell and the signals come through sharp instead of scratchy. Give that field a few more passes after rain and you might be surprised what else is sitting just under the stubble.
