When to the old park and hunted in the woods,had my sharpshooter coil on, Get a nice tone and my readings were bouncing around 67-75 and 4-5'' deep.My thoughts were I have a wheat penny,out comes a ------I think a train wheel------ check the hole with the pin pointer, something still in there,I get a penny and see its a Memorial,re check the hole,another penny,re check and another penny. I found 19 Memorial Penny's from 1959-1976. These pennies were 6''x10'' area. What is crazy is there are some more there,my pin pointer died and I'm spoiled using it.I didn't feel like getting a hand full of dirt and checking with the coil. I did mark the spot and will see how many more are there next time out. Hey its a penny---------after1-----------
