I went to old cellarhole with a little snow it took me half hour to remove the snow . I warmed up the coinstike and was getting nickle reading left and right in the bottum of cellarhole. I dugg a few and they were shotgun shells and i got this strong reading just a little higher then nickle and kept on pulling buttons one after another. I figured someone must have had a sewing box hummm???????? ps the plain buttons are below i found a gold gilt odd square shape lead back object on your left far bottum pic it a ladie profile on it
