Spruu, its the YouTube science channel, isn't it?. Possibly if one had a wave analyzer to detect the ultrasonic distortion of air currents of a series of coins dropped from the EXACT height, landing at the same identical(not similar) angle, and at the exact (to microns) spot, a ping test could be deemed "scientific, toss in control groups and all.
Oh, I forgot temperature and air current motion must be identical as well.
Doing the ping test isn't really as scientific as you think. I recommend the OP get the coin XRF analyzed. Then we'll have facts instead of "I think that one sounded different..."
Seriously though, there's some super information here, and I appreciate it.
I am going to try to get one of these "high-reading" nickels from my friend, and go from there...
Hoping to luck into the ability to have someone do an XRF analysis on it, and if not, it will be time for a plan B.
Keep the thoughts coming, if there are any...I'm really interested in the history here.
Someone posted that there were some 1943 P coins minted on nickel/copper planchets. They had the "big mint mark," I assume, suggesting the 35% silver " War Nickel" mix, but they WEREN'T? That might be just as interesting as a War Nickel that is supposed to have manganese, but doesn't...

Wow - a bit harsh there. This forum is for learning, asking, and sharing, and its normally done in a manner to help.
Unless a post is directed with an "@member," everyone just assumes its all open discussion. And even if an @member is used, most of the time its still open for discussion.
I think Spruett's request was being courteous enough, and I suspect he asked so everyone could get the Reader's Digest version from someone who understands the ins-and-outs, rather than people having to wade through Google links.
Please take this as constructive - maybe you were just having a bad day - we all do at sometime. I see you took the time to locate/post youtube vids, so why not just post the info that was asked for? The community thrives b/c of questions and answers and we appreciate everyone's input/expertise.
I have been told that an XRF test is available at some pawn shops and jewelry stores - perhaps for minimal or no charge. Of course a materials testing company is sure to have an XRF.
If I can't find one at the University, I will try jewelers/pawn shops for sure -- thanks for that. What, though, would be an example of a "materials testing company?"
Meanwhile, my plan A is working, so far. I have made contact with a professor in the Geology department at the University, who has an XRF analyzer, and he is going to have someone get in touch with me (so he says) who can help -- so good news so far.
I will! I appreciate everyone's help, and wouldn't even have known about XRF analysis were it not for the suggestions. I'll definitely let you know what the results are.
Should I do it in a new "results of the nickel analysis" thread -- since it may take a little while, or just resurrect this thread when I have some info to share?
