Took the X-Terra 50 to an old Country School yard today. Didn't find a lot of coins, but some days are just like that. Managed to pull up two IH cents, 1900 and 1903, and two old Wheats, 1910 and 1911. Both Indians read a consistent 27 with no wavering. The Wheats read a 27/30 with consistent tone. Top pic shows how they looked as they came from the field. Bottom pic is after a cold water rinse. Chemicals in the soil sure took their toll on these copper cents. Glad it don't have that effect on silver. HH Randy
