I cleaned out some old junk from under an addition to the house. The wife said you should check it with the metal detector. Ok soft dirt looks clean not like the backyard. in a few min. i get a very high tone In relic 2 tone on .it says 6inches but nothing still ringing and i remember reading if it says 5 inches and you dont fine it its prob.a good target. so i dig about 11 inches and pull out whats looks a half dollar .Im having fun now clean it off to see an inbossed face of Napoleon with the number 1 and that's all nothing on the back but very good shape and clean.I was relay hoping for an old coin of some kind but this will do .dint know what it is so if anyone has any ideas i would love to here.And thanks Aarong81
