I need some help from someone who collects this series, and has a good scale. The New Zealand 50c coins from 1978 to 1989 were struck at the Royal Canadian Mint, on copper-nickel planchets. I have found that weights can vary a lot on coins not struck on intrinsic metals. So I would like to see some examples of this coin, photographed on a scale. Why you might ask? Well, I believe this Canadian dollar coin was struck on a New Zealand 50c Cu-Ni planchet. And, I'd like proper attribution on the PCGS holder. https://www.PCGS.com/cert/43870508But it weighs 12.7 grams, and the Krause shows the New Zealand 50c coin to be 13.61 grams. Most New Zealand coins I have seen, are often slightly lighter than Krause listed weights. Thanks in advance.

If the planchet is way under spec for a NZ 50c, I doubt that PCGS would certify it as such - and any proof that NZ 50c can be found that far underweight would probably be taken as circumstantial.
Is there a list of countries the RCN made coins for in 1981/2? Though it might not even be a coin blank, if the RCN was in the habit of making CuNi medals or tokens at the time.
I do, however, have a large stockpile of NZ 50c pieces right now (apart from the ones in my own collection). I'll see if I can get some weights for you later today. But I would think the chances of finding a match here are unlikely, simply because these coins need to be good weight if they're going to work in vending machines. A coin that's a whole gram underweight when freshly minted would probably fail a coin-op test.

What does the edge look like? Reeded? Smooth?

The planchets used for NZ 50c pieces were smooth-edged; the interrupted-milling pattern seen on the coins was applied by the collar die. So an NZ 50c planchet fed into a Canadian $1 press should come out with the usual milled edge expected for a Canadian $1.

T The only RCM minted coins of Cu-Ni composition remotely close with those dates are: New Zealand 25c: 11.33 grams Australia 20c: 11.42 grams New Zealand 50c: 13.9 grams It could be struck rolled thin stock in error, which most planchets could have been rejected, but then as you say, PCGS will not attribute that. However, if I could demonstrate a handful of coins being under 13 grams, it might change their mind.

Sorry but none of my NZ 50c coins weigh less than 13.6 grams.  |

The reason why I asked edge is because I have an error Australian 1981 10 cents with the edge of Sri Lanka 50 cents. This is how it was determined that it was from Sri Lanka

I seem to have gotten rid of most of the NZ large 50 cent pieces I had, but of the 25 I do have at hand, most were between 13.61 and 13.66 grams. Only two were "lightweight", at 13.32 and 13.20 grams. (one of those was dated 1974); none were under 13 grams. More were overweight than underweight, with several reaching over 13.70 grams.

I ordered a couple on eBay. But I already suspect that what I have was not struck on the New Zealand 50c planchet. So that leaves: 1. struck on thin rolled stock intended for New Zealand 50c coins, that was most likely rejected for the production run (how it got struck by Canadian $1 dies would be a mystery). 2. struck on a planchet intended for another country, and not reported by the Royal Canadian Mint. That means I need to do a loooong and slow search through the Krause catalogue. 3. mint shenanigans (which seems possible, given all the other weird stuff you see on the Constitution series dollars). Thanks for the input everyone. "Discovery follows discovery, each both raising and answering questions, each ending a long search, and each providing the new instruments for a new search." -- J.

I have no records of the RCM striking any coins for Bermuda, but supplying planchets might be possible. But, considering that was more than 40 years ago, I'd have a tough time proving it.
