I find lots of nickels.
The first pic below is the amount of clad I have found in the last 5-8 weeks or so.
The second pic is the nickels culled from this pile.
There are definitely less nickels than quarters or dimes, way less then the pennies that are not shown, but they are out there.
Why do I find so many nickels?
Theory..
Lots of these were found with a Vaquero and a Compadre and both of these units run at a little higher frequency than several others, from the 12-14.7 kHz range.
I believe detectors in this range are a little more sensitive to not only gold but nickels, too.
My Compadre goes further on a nickel than it will on a quarter or dime.
However, a good portion were found with my lower frequency F2, also.
I am a dig it all kind of hunter, usually.
I am always looking for gold so I tend to dig most every solid signal from the just above the iron nails range right on up through foil, nickel, tabs, zinc and beyond.
I can tell you from experience that nickels can be very funny and even though they are supposed to come in at a certain range, (for instance on my F2 a 33 VDI # is usually a nickel), many many times they don't.
I have dug a lot of nickels that ranged from down in the mid foil section all the way up to almost zinc, and this was with all my detectors.
Don't know why, maybe it has something to do with soil conditions or their position in the ground, but I have been surprised many times when a nickel popped up when I was expecting something else.
Because gold comes in so many shapes and sizes and can come in literally anywhere in the range of most detectors, when you look for gold as hard as I do by digging all solid signals and even some that aren't so solid, a by-product of hunting in this manner is going to be recovering plenty of nickels, too.
This is just one of those coins that tends to disguise themselves and can hide in garbage areas like foil and tabs.
This happens more than you realize, in my experience.
So if you want to find more nickels...and probably some gold if you are lucky, you just have to take the advice from me and several of the other posts above...
DIG IT ALL!!!
