Yesterday, 4 of us hunted several house demos in the Houston area. As a group we did well with silver coins. On a place they had just taken down a 1910 house I got a 12-38/9 at about 5" and I dug it and out came a small dime sized dirt encrusted silver coin. Thought I had another Rosie, then saw the '1/2' and thought "1/2 dime", naaahh! A 1905 'Deutsches Reich 1/2 Mark' in pretty good condition except for the hole! Also got a very good condition 1887 IH there.
