Hello, I wanted to see a direct source to make sure that the 1974 Commonwealth Games Proof Dollar from New Zealand is indeed silver, just so if I ever sell it I know I am selling a silver coin. I ask because New Zealand had copper-nickel proofs at the same time, and it's odd that a silver proof dollar appeared in the 1974 proof set when previous and subsequent years had them minted in copper-nickel. If for some reason official mint reports contradict the notion that the coin is silver, I would like to know before I decide to sell to avoid ripping someone off.
I was looking moreso for the official mint report from the Royal Australian Mint. I understand NGC uses Krause, which is prone to having mistakes in its catalogue. The report from the mint would be a more reliable source from my point of view. I tried accessing the 1974 Royal Australian Mint report from the Australian library online, but it kept giving me errors. I was hoping someone would have access to that primary source.
I know this seems like an obvious answer, but I just find it weird that New Zealand would shift to a silver dollar and then continue to mint proof dollars in copper-nickel. Having clarification from a primary source, like the mint itself, would be nice.
1974 NZ day 1$ proof was CuNi but Commonwealth Games 1$ proof was only silver (km#44a) according Bertrand catalogue of New Zealand coins (2024 edition):
New Zealand • 1 Dollar - Elizabeth II (2nd Portrait; Commonwealth Games, Silver Proof)
