Know this is the Classic site but a good find to share. Got them this morning at that 100 yr old house just before they started digging up the whole yard for a new septic. Couldn't believe my eyes when they came up. Signal real strong and loud, down about 10"s in the same hole 1936-s and 1943, haven't gotten any silver halves in a couple of years.
