Ok, just to kinda get back on track. CAN WE ALL CONFIRM this is not a transitional error? Only a 1946 with dark toning?
How can a person determine that without scientific analysis of the metal? The chances it is are astronomical, but if one wants to use their money to test it, then it is none of my business. I think the amount of silver in a 'war nickel' is too low to use the magnetic test that some bullion people use, so XRFSpectrometric is the least expensive nondestructive testing if you can find someone with a XRFS gun ( used about $10,000) so most charge 50 - 200 to test a sample. I do not know what test a TPG would use. The odds are about like my city being hit with a meteor next week. But I hope Santa brings me that type of gun for the holidays.
If you want to see real nickel errors, here are three nickels from my collection that are true errors on the wrong metals. All with full dates. 1. 1987 Nickel on clad 25c stock (only 7 known for any year). 2. 1969-S Nickel on a 10c planchet. 3. 1979 Nickel on a 1c planchet.
I was once a new member, but no one ever made fun of my posts. Why? I do my research and don't believe in unicorns!
Reminds me of a book my daughter has. The unicorn gets made fun of by the other unicorns because she believes in little girls.
QUIT MAKING FUN OF UNICORNS! JUST CAUSE YOU HAVENT SEEN ONE DOESNT MEAN THEY ARENT REAL!!!!! MY PET UNICORN IS WORTH MORE THAN THIS 1946 NICKEL!!!
If a person had good lab instrumentation, it might be close, but we would have to assume the % of each metal was right on specs as copper and nickel are 8.9, and pure silver is 9.5. One problem is tolerances of measurement, the other is a suspicion that the mint might have cheated a little on the silver percentages as it was a war need also for nuclear design and manufacture in the middle of the war, so I personally would rule a sp.gr. test out as deterministic.

Since the war nickels and regular nickels have the same size and weight specs, wouldn't that indicate that the specific gravities are pretty close?
To the OP. An SEM/EDS analysis would work well. Many Universities have this type of equipment and some will do outside work at reasonable prices. You'll spend about $100-150 but there will be no doubt if your coin has Mn and Ag (war nickel) or Cu and Ni (regular nickel). I am not a big fan of having dealer use handheld XRFs for things other than gold and silver. Not a problem if the operator knows the limitations of the equipment, but there is a lot more than just pointing and shooting and reading numbers off a small screen. Just my opinion.
