This old Pontiac city park has a lot of potential.Myself and three other hunter's went in search of old silver coins.Once at the park we all went in different areas to search.My strategy use a very slow business like search and try to find wheat's to find the silver trail.After searching for about an hour I had found some clad and a couple of wheat's.Later on another two wheat's and I got a 180 ID on the meter with a nice deep rounded signal.Once the flap was removed I placed the sunray probe in the hole to locate the target nothing,switching back to the coil and a sweep revealed the target was still there.Digging deeper in the hole now the Sunray probe got a signal and after another adjustment I could see the silver edge of the 1914D Barb Dime.Two more wheat pennies and 176 showed on the meter,which I just knew was going to be an Indian Head penny.This target was a complete surprise this coin was half the size of a dime and was silver ,which was a 1880 Canadian 5 cent piece.Finally after another hour of hunting and a couple more wheat pennies and a 1949 nickle I ended my hunt.The other hunter's had a bad day only clad no wheat's.
