spotted a sidewalk tearout in a small town on the way home from work, I had my etrac in the trunk so i jumped at the chance to hit it while I had time. I managed 14 wheats, oldest was 1912, 2 indians 1893, and 1908 (and there was NO "s") 2 merc dimes 1920 and 1937. The 1920 was lying right on the surface of turned up dirt, gotta love that! Found one marble and a few odd items..........not a bad quick hunt!
