Just to tell you guy what I think, after hunting for more than 20 years and
incountering this type of situation several times, my true gut instinct is to say
that peaple lost what they had, and if your hunting an old poor black church,
or a residencial home that was not of an upper class person, they probably did not
carry lots of silver on their person much of the time.
As for those hound dogs that cleaned out all the silver and left the Wheats, well
the truth of my opinion is that most of the older machines that just had
knobs for discrimination could not distingish between a copper penny, and silver
dime, anything that high sounded the same and sounded good and I dug it
to discover what kind of coin I had......
But I truly find it hard to believe that anyone who is digging lots of silver
will not stay and dig other more iffy targets just because they are lazy or
in a hurry...
Only todays high tech machines with a digital meter can distinguish a silver dime
from copper pennie, but still I have dug silver on copper pennied signals....
Normally worn, pretty smooth.
my odds guise is one silver dime for every 10-12 wheats dug,
and a silver quarter for ever 8-10 silver dimes...
just my 2 cents worth....
