Quote: I tried to find without success foreign coins that fit those caracteristiques and produced by the Mint at that time. Aside from the Jamaica strike after WW1 and Newfoundland, the Royal Canadian Mint did not start producing coins for other countries until 1970. Your coin was struck on a planchet that was split before the strike. The nickel 5c planchets back then were produced from nickel powder by the Sherritt Mint, and sometimes they were prone to splitting. Most examples I know of were split after the strike, but I have seen an few examples like yours, all from 1962.

Wow! Noce split planchet and a great find! I had never heard that 1962 nickels had this issue. Now I want one to add to my collection lol.

Thank you SPP-OTTAWA for the detail explanation.
I was close with my thin planchet option, but the split planchet is much more better.
We can clearly see the powder granularity on the reverse.
Case Closed !

Do we know the period of time where Sherritt produced planchets for the RCM?

When you are very lucky you find both halves 38 years after they were struck!!

I found an interesting paper about the Sherritt Company. https://gosling.ca/Sherritt/Sherrit...Research.pdfThe document containing numerous papers and other materials about Sherritt's history. A lot of work. I haven't had the time to read everything, but there's an interesting paper on page 42 about Canadian coinage based on the sintering process of nickel (metal powder compression). Sherritt developed two concepts for the Royal Canadian Mint ( RCM): one based on power-rolled strip and the other on static compression of blanks. Initially, nickel planchets were produced by laminating ingots. The nickel strip produced by the pilot plant was retained, but the actual setup produced too thin metal sheets. Therefore, they had to overlap and compress two strips together to achieve the desired characteristics as per RCM requirements. Unfortunately, this method produced blanks that sometimes delaminated. This problem was resolved with the formal manufacturing plant. All this work was carried out in the early 1960s. Sherritt produced some demos in 1961 and secured the contract from the RCM in 1962. So, I think this explains why we only find split versions of the Nickel for 1962. Early deliveries in 1961-62 were based on the pilot plant with the laminated two-sheet method. Subsequent deliveries were made from the formal plant without this issue."
