Your opinions please...
Say you hunt a nice grassy lot in a residential area. The lot is surrounded by houses from the early 1900's on two sides and from the 50's and 60's on the other two sides. For as long as the area has been residential it has been an open lot, and before that it was farm property. You hunt for two plus hours in very dry conditions with the E trac in auto and the sensitivity in the low 20's the whole time. Other than a mess of clad, you dig 14 wheats (1920's - 50's), two Buffalo nickels, and some Jefferson nickels from the 40's.
Now, which of these would be the most likely explanation for the lack of silver?
1 - No one ever dropped silver there.
2 - Silver was dropped there, but the spot has been hunted and cherry picked.
3 - Silver was dropped there; you were just unlucky and didn't pass your coil over it.
My best guess is that is was some combination of numbers 2 & 3. Your thoughts?
