Took one of my M-6s to the k-2 school next door.. Playing with the 6x10DD coil and I found fist full of clad and a few wheaties.. The coins in the middle of the picture were stacked on top of each other 2" down!! At the edge of the swingset it locked on a half dollar, and there at 4" was my first Kennedy..Not the usual clad.. As I continued to detect I found a lipstick case, and a toy car.. Good day I thought as I was about done..Must of been, as I was leaving the schoolyard the M-6 got a "A" of thin brass or copper..
