Was metal detecting a hundred year old church here in Delaware ,I went to the parish office and got permission from the Secretary.After digging up about 13 rosie dimes, I got a solid fifty -cent signal at 8 inches.Last time I got a fifty cent signal it turned out to be a boy scout pin as big as fifty-cents.After removing the grass plug and diggin out popped two silver quarters at 8 inches This machine never ceases to amaze me.Only detected for about 2 hrs and bagged over six dollars in quarters and dimes.Will go back next couple days to finish up. Nothing back to late 1800s yet. Wayne
