Does a silver war nickle have any distinctive sound when Dropped on a table.If it does make a comparison.I'm sure somebody has a better Idea

Try flipping it in the air and compare to a war and non-war nickel. The war nickel vibrates with a higher pitch, I believe.

clang 2 regular coins, then that coin with a regular coin, if they make a difference, then you MIGHT have one.

Sure looks like the way war nickels wear. Can't use weight because both alloys weigh the same.

This is a quick test to see if your coin contains silver. Place a tissue paper (Kleenex) over the coin. If you see white through the tissue where the coin is, it is silver, if you see the shadow or darker outline of the coin it is of another composition.

Electrical conductivity (eddy current) would be feasible, with a shielded ferrite core probe. Compare the war nickles conductivity (known standard) versus your subject nickle (unknown).

Got access to a metal detector? Run some tests with known war nickels and coppernickel alloy pieces you will find the detector will generate different tones for the two different alloys. Then see which one your coin matches. Not absolutely conclusive but fast and pretty accurate, and if it does match the war nickel then it would be worthwhile to have the specific gravity test done or spending the money for professional authentication. If it reads as coppernickel then it mostlikely is.

I am definitely interested in this topic. Hopefully you do have a silver!
I did have a 1965 Dime once that I thought may have been silver, but it was indeed just the toning and wear combo that made the clad piece look like that.
Coininvester: If the coin was minted on a wrong planchet, it will not have the mintmark above the dome. The dies for 1946 were not created like that, but being only one year from when silver nickels were minted, it is a great possibility that a couple silver blanks made it to the next years batch.

Since your coin had the same results with the kleenex test I would have a special gravity test done.

I sometimes forget where I am at occasionally, usually at work. I happen to perform Nondestructive tests, and the ferrite core shielded probes are readily available at the "office". I made some people mad when we performed conductivity measurement tests on their jewelry, only to find out that it was gold or platinum plated. 
The metal detector generates eddy currents (currents generate fields and the those fields generate currents), so this method has merit to it. Hopefully you have some sort of display to differentiate between the two materials, and not the tone type. I se that you don't have a metal detector, but this may be a good time to have one demonstrated to discriminate the metal content.
