I was very lucky to find these. I used to detect (had to sell my detector to survive a divorce a couple years ago) and never found anything as nice as these. I purchased a book from a local detector store (Digging Deeper with the DFX) and it made all the difference in the world. The beach where I found these were very clean, in the 3 days I was there I only found $1.57 in change. The book allowed me to reset the DFX to find things a lot deeper than other detectors. These were 6.5 inches deep and right at the water line, either other detectors couldn't find them or they didn't want to dig that deep.
