Left to right,   Coppernickle, 10% silver, 40%silver, and .999% 

 

For the sake of accuracy: the 1968 Kennedy, while 40% silver as you said, is made up of two outer layers of 80% silver and 20% copper, bonded to a core of 21.5% silver and 78.5% copper. That makes it 40/60 silver/copper. So, what you are actually seeing under the tissue is 80% silver.

Well alright. Yes, I will then accept that they are probably cupronickel. Idk what specific gravity or an XRF gun are but if the tissue test is close to 100% then I should accept that. I gotta admit I didn't expect all this controversy. Now the main thing that has got me still so against it is that none of us have been able to even find these 5 coins online anywhere in Cupronickel. We have all, as well as several others, found them in Silver and have found plenty of different coins in Cupro, but not these 5. Surely that are not so rare that photos are unavailable or so popular that every single set was sold and not a single set has come up for resale? I mean, I found information about a one of a kind Token that was known to have existed but had never been photographed for a guy and found the guy that had the other similar ones from that particular town. So why can't I find anything on these?

Here is a 'complete' history of the Isle of Mann. At the bottom is supposed to be every coin produced there and nowhere are there Planes of WWII, which made me remember my first thoughts that they are counterfeit. Couldn't they be made from Tungsten lime my friends Morgan?

Tungsten would weigh close to twice as much as silver.  Silver has a specific gravity of 10.5 grams per cubic centimeter,  Tungten is 19.3.  Tungsten is normally used to fake make gold, which has a specific gravity of 18.88.

Well spoon!  You guys don't have to keep at this. I know your time is valuable and may be better spent helping the rest of the Newbies. I am at a loss as I don't have y'alls resources or knowledge so I don't see how much further I can go with it. Between me, all of you, and 3 guys from my FB Group we have likely exhausted any available resources that we know. So if you want to quit I certainly won't hold it against any of you. And I totally do appreciate all the hard work and research you've done.

Here a few others that I found with pictures that match your coins. I found the others without pictures. The specs are the same for all of them.

Hey Coinsandmedals! Glad to see you Friend. Dukeman also linked me to the Numista site and I had been there also. My question now, and I am so freakin confused that idek if it is a valid question anymore, is how can the Silver and the Cupronickel weigh the same? And also why can we find these coins at all anywhere if the site for the Isle Of Man doesn't list them in their history with all the rest of their coins?

Aslo not exactly your coin but I was able to find one similar straight from the source.

I also reached out to them because it looks like their silver proof coins have identical specifications to the Cupro Nickle. 

We are getting closer to solving this puzzle :D

They also mint collectibles in something they call Nickle Silver.

Dear Manuel

 

I can confirm the coins were minted in silver. They would, in picture, look identical. However, the silver coin would have more or a mirror finish when compared to the Cupro nickel version. It should also be kept in an airtight capsule with box and certificate of authenticity. Where the Cupro nickel will likely just be in a coin wallet with no paperwork.

 

If you have any queries, feel free to contact me.

 

Kind regards

Gareth

 

I hope this helps conclude the decision @KarenHolcomb If your coins have a Mirror image then there it is, they are silver. 

If you want to perform the specific gravity test.

Hey Dukemnm, this is helpful as mine do have a very mirrorlike finish and were received in airtight holders. I took them out to photograph them. I just figure anyone could have put them in there. As soon as I am up and at em I will try this gravity test and let you know. Thanks a bunch, that was definitely above and beyond.

Well, that settles it, they are silver.  

I also reached out to PobJoy mint. I think they are the official mint for these coins, here is what they said;

Thank you for reaching out. This is a good question as you are correct, they have mostly the same specifications. 
 
However, Copper Nickel is a much harder strike, therefore it doesn't have as smooth of a finish. Also, if you put one CuNi coin next to a Silver coin on the table and lay tissue paper over the top, the Silver will really shine through while the CuNi will be much more dull.
 
In addition to all of this, our Silver coins come encapsulated and in a presentation box for better protection, our CuNi coins come in a plastic flip and a Pobjoy pouch.

Do let us know when you conclude the gravity test. I'll be curious. :D

Ok, well I am not able to do the gravity test because apparently my scales spoon. I have been trying for 3 hours and haven't gotten the same read twice. And I broke two legs off my tripod. One and I could still work it but two gone is a lost cause. I have never had an issue with my scales before. I must have made at least 100 videos and now I have a headache. I'm not quitting. Only taking a break from it. If y'all wanna try and figure it out, my Zombucks are .999 Copper and weigh 28.98gms. In the water they were averaged at 3.28. I used them because they are nearly exactly the same size in thickness, diameter and weight. The questioned Queen is 28.56gms and in water averaged in at 3.17. My scales won't stay on tare. Idk if it's the water left on the coins or what, but it has me frustrated and I don't like that, so a break I shall take. Until tomorrow then. Maybe I can borrow a scale from someone. Would Triple Beams works?

FYI, I am still working on this. I did get quite frustrated and had to out them away for a while and today I found that I have a friend that lives kind of close to me that has the gun thing to tell me what they are comprised of. I haven't been able to do the specific gravity due to the weight limit of my scales. So hopefully I'll find out soon and let you all know. Because i am positive that you've all been waiting with baded breath. Right?
