hmm sorry would have to agree with nancy here just a scratch and not a die crack, or lamination flaw. You might want to take zoom up photos that are in focused as its offend very hard to spot die cracks.

It is hard to follow, but I don't think Allcoinage is referring to die cracks, but actual physical cracks in some coins after stamping.
He has a thought that the design of the queens head has an inherent weakness (a stress raiser so to speak) which runs from the chin, up to the bottom of the earlobe and then accross to the left hand end of the tiara/crown. It may not be those points exactly, but I think that is the gist of his theory. He has raised this in several other topics previously.
I have no idea if it is right or wrong, but as I've stated before, I am open to any idea until it is put to bed.

Yes ttkoo that is what I'm addressing here about the weakness in that area, it could be a problem for ram mint if this isn't dealt with, I wouldn't care if I had an error coin or not  |

OIl doesn't "leak out of cracks" on a coin, because there's no oil inside a coin to leak out of. And the oil stains weren't transferred from the die, because again, a coin die is a solid chunk of metal, it can't crack and leak oil out of it onto a coin. Further, coin presses operate at such high speeds, they don't use "oil", they use high-temperature grease - which is why "grease-filled die" varieties are a thing. The stains on your coin came from something outside of the coin - in other words, environmental damage. It's possible that a PMD crack formed on the coin, after exposure to heat and/or chemicals. The coin was then dumped in the staining environment, and the stain stuck to the crack better than the rest of the coin. But all of that hapened to the coin long after it left the Mint. The RAM has no control over what might happen to a coin after it's finished making it, and certainly can't control how a coin will react when it comes into contact with a chemically hostile environment.

All Australian coin blanks are made in South Korea. They come already washed and rimmed, ready for striking.

None of the coins shown actually have die cracks on them. Look up Pareidolia, it could explain what you think you are seeing. life is a mystery to be lived not a problem to be solved
