I've hunted my small yard repeatedly since I got my Ace 250 back in January 2012. My house was built in 1932. I thought it was hunted out, but so far this year I've found a 1924, 1925-D and 1946-D Lincoln and my wife dug up the 1905-O
Barber quarter.
I had my detector out on Monday and was swinging it under the bushes right by the doorway when I dug up this nice 1937
Buffalo nickel. Fortunately, the soil here in SE Wisconsin is very kind to coins.
