smallcentguy mentioned earlier in the thread that in 1989 36 million new Zealand 5 cents were produced by RCM. it wouldn't be too hard for a planchet to get stuck in a machine or transport bin. |

Colonial Acres is selling a 2006 specimen set with a toonie that has a centre core containing titanium instead of aluminum.
Where did THAT come from?

Titanium is definitely wrong. The standard alloy was copper/aluminum/nickel.
It could be a goof in the sheet coil. But then you'd think there would be lots and lots of these.

yes, one would guess that if there is one core with this alloy, probably many more like a whole rolls worth of these cores.

If that analysis is right I assume it probably is then thats a nice error set well worth the money, IMO. Although without an analysis you would never know. There has to be more out there unless it was a single planchet mix up. wish there was an app. for that lol

There is nothing wrong or abnormal with that Twoonie being offered. The problem is with the analysis that was conducted on it. If you use an old Russian-built XRF, you can expect titanium in just about everything you analyze (titanium alloys are used to shield radiation, the interior shielding of most XRF machines)... I have tested these twoonies with multiple instruments, and even tested one whereby the twoonie was taken apart - they are not compositionally different.
I have told Lower Canada Auctions about this, who sold one at Torex last year, but it fell on deaf ears. I have also had discussions with Bill Cross, who refuses to acknowledge this "titanium twoonie" even exists, unless one of these Russian-XRF tested examples (which all come from one collector) was sent to me for both quantitative SEM analysis and a test on my XRF.
In summary, save your money. You can find these "whitish-cored" Twoonies in many different years of Specimen and PL sets....

Spp to the rescue..lol Glad you chimed in and informed us. I take it back what I said about worth it - "Not worth the money"

I just received my penny back from SPP - Ottawa. what a great guy for testing it and confirming it as a new zealand 5 cent planchet. he also estimated its value between $100 - $150 and graded it AU scratched. the xrf machine confirmed 73% copper and 27% nickel. thanks SPP-Ottawa!

@SPP: That accounts for the false titanium. But where did the aluminum go? The claimed percentages add to 100%. Are these Russian XRF at all reliable? Without a TPG certification, how could you know you even get the tested set? Did CA verify? Some guy comes in with a set and an XRF results sheet, and they bought it? Does CA expect you to go out an verify the XRF? Will they refund when it fails? |

But where did the aluminum go? Aluminum is a light element. It won't even register on an XRF set up to deal with alloys and if it does, the machine is getting interference with the energy peaks (the detector measures spectrum peaks) and providing erroneous values. When I have to deal with aluminum, I have to switch to software packages and X-Ray beam settings capable of dealing with lighter elements.... Of course it adds up to 100% - that is the sum of the interpreted spectrum peaks, no matter what the detector is.

I would have assumed that a test setup to detect the old toonie core was for the situation it was expecting (aluminum in the mix).
I'm reminded of the great rule of thumb: Never assign to malice what can adequately be explained by stupidity.
