Anyone ever get a high tone on a nickel? I was out this past week at a site and got a 13-41 signal at around 6 inches with a repeatative high tone in all directions. I dug down and ran my pinpointer in the hole and discovered a nickel. I was a bit puzzled and layed the nickel on the ground and scanned and got 12-14 signal. So I then proceeded to look for another coin and found this rusty bolt. I didn't look at the nickel very well at the site. Later that evening I kept thinking about what I saw and heard and got the nickel out and examined it and noticed it was a 1944P moderately worn. So It got me to thinking and "ala" the ole war nickel which is 35 pwercent silver. Maybe that's the reason for the high tone and conductive numbers.
