Research on a park in my NJ town told me an old house was once there, maybe a farm. Dug lots of deep nails and some interesting old metal things there in the past, but no older coins, no silver. This coin was near where the house was and finding it tells me more about the age of the place. Was in Disc mode using the 7" concentric coil, got a high tone and switched to All Metal to check the depth, the signal strength sounded like a penny/dime at 5" deep. Coin was 7" deep was under a tree root. Dug up old metal things in the socker field there too, going to spend more time at this park. The only other NJ copper I found was back in the 1970's in the front yard of an old house 3 miles from this park.
