Man 55F and the ground has thawed. Decided to get in a short hunt. Went to an area where I played baseball as a kid. Once a year this same area was used when the Circus came to town. I hunted an area about the size of a baseball diamond. I recovered a 1939 Merc dime, 4 wheat pennies 1936, 2- 1944, 1945. Also recovered 3 Rosie dimes and a 72 Kennedy half dollar. My X-Terra-70 then gave me a very sharp signal and a solid 42 on the meter. I thought for sure I had a silver quarter. At about 8" I recovered a one peace brass button. There is no writing on the back. I'm thinking WWII but now sure. Can any one identify. Thanks TomB
