After reading all the input about how deep and how accurate detectors are, I realized that I have been all wrong for the 40 some odd years I have been detecting. I always put too much faith in the numbers and digital reading of my machines. I took it for granted that unless a dime or quarter or whatever signal came up on the screen, then it was probably junk. I now realize that some coins can give junk indications when they are deep or close to other junk. I will be digging anything questionable from now on. I can only imagine what I may have left behind over the years. I put this to the test this afternoon when I went back over a location that I thought I had all cleaned out. I concentrated around a large maple tree and its roots and started digging iffy signals. I did manage to dig up a number of nails and other iron junk, but suddenly got a pull tab reading from under a large root and started digging. The pull tab turned out to be a 1934 Washington quarter. I will post this and several other coins on Todays Finds later on this evening. Who says you can't teach an old dog new tricks. Thank you for the discussion contained in this forum.
