A 20 cent blank should be slightly thinner than a 50 cent blank. Simple and easy way to test if is a 20 cent blank or not: Comparative ring tone test against a known genuine 20 cent coin. If it sounds the same, I would write to the RAM about it. They may wish that you submit it for further testing to confirm your suspicions. Coins struck from blanks intended for lower face value coins are not EXTREMELY rare. I have about 5 or six such errors produced by The Royal Mint in Llanstrisant, but none produced by the RAM. |

i have tried to take a photo of the edge but with no success, there is no reeding on it, yet it is the same thickness as a two bob, measured up against a fifty, there is a considerable thickness difference. the un-rounded section is slightly thicker than it is to the opposite side. I will continue to try to get a picture of this. if it was ground down in a back yard shed, would it not be the same thickness all over ?

Why would there be reeding? Reeding would only be on a coin struck in a 20c collar. On the other hand, flat sides might get squashed onto a round blank if there is enough pressure. I would expect a round blank to end up thinner and larger diameter than a 20c if it went into a set of 50c dies. I am expecting this one to be PMD. |

On further thought, I am not so sure if this is PMD. The round rim on the right side may be from a 20c blank? What is the diameter compared to a 20c coin? |

it is slightly bigger than a two bob, however this is slight, maybe 1mm or so all round

PMD caused by someone deliberately removing parts of the coin in an attempt to make it look and seem like a 20c coin. Show us the other side, and I'm certain many more will reach the same conclusion as me. If is is supposed to have been minted on a 20c planchet, the planchet would now be very noticeably thinner, as it has been flattened out when supposedly minted as a 50c coin, so it wouldn't be thicker, it would be thinner. If there's even the slightest hint of it being thicker anywhere at all, then it's a 50c coin that's been mutilated.

here is a pic of the other side, the only part of this coin that is the same thickness as a 20c is the part that looks like a fifty, the rest of the coin does spread out slightly thinner. no part whatsoever is the thickness of a 50c .  |

I don't have the experience to say if this is real or not but if it is then it is worth a heaps of cash!
and I am sure that RAM will want to know about it
I wish you were in wa so I could see it

I'm not sure. What does the edge look like on the top? Can you please take a side photo of the top where supposedly you should be able to see the apex of the 12 edge coin? If this section is round, you might have something.

I don't know the exact minting process, but I am wondering why the angles and raised edge appear at the top of the coin? Surely they only appear when a 50 cent shaped planchet is used with a 50 cent rim collar die? Wouldn't this be the only way a raised edge would be formed? I would be thinking the raised edge and straight angled rim could only be formed in a 50 cent minting process?  Of course, I might be way off the mark ... |

I must  with you enworb, proper pic's is needed here. With my limited knowledge it seem's to good to be True. Why is the coin's strike so central, Couldn't the Spread of the Planchet go off in a different direction in the Collar instead of a Straight Strike (12 o'clock & 6 o'clock) jpl.. Edited by jpl

Could it be a dramatic elliptical clip?
