Here's an Australian Penny which I've tentatively identified as a doubled die reverse, although I'm unsure which class of doubling this would be.  There are a few interesting details, such as where the "doubled tops of STR (see photo) are nicely aligned, yet there's a dramatic offset at the bottoms of the letters. Perhaps the tops are only MD? I particularly like that ghost K above the designer's K.G   Edited by KurtS

Have to confess I don't understand DD & MD, but you've certainly got an eye for picking up any interesting differences! life is a mystery to be lived not a problem to be solved

Thanks Nancy! I think one difference here may be that US collectors have high awareness of doubled dies, due to the classic 1955 and 1969-S doubled die Lincoln cents. |

Hi, Looks like Machine Doubling on STR. I wonder if the other stuff isn't die clash. To be honest I am not sure and would need to think about it more but I have kids to take to school. Mark |

Thanks Mark for your input  Others have wondered the same, although how does one explain the doubled star point, the K in KG, and look at the PE in PENNY? |

That could be the DEI from a die clash under the PENNY. No idea about the star! Spectacular looking coin whatever it is.

OK I've just superimposed a mirrored obverse of a penny over your image and it's not die clash. The marks dont seem to line up with the obverse legends at all. Must be die doubling. It's very spectacular.

Mark, my overlay supports your conclusions. The legend on the obverse simply is in the wrong location to create such marks from a clash. I'm more confident than ever this is a doubled die--thanks again for your input. Here is my overlay. I re-shot the coin to ensure the scale between obverse/reverse was very close. Fortunately, two denticles almost exactly align obv/rev--the result should be fairly accurate:  Obverse as reference for devices:  Edited by KurtS

Not being familiar with the "Aussie" coinage, I was not aware of the "doubling" on the chest area of the 'roo. The only area that I could comment on is the "ASTR", where the top of the portrait is, but that doesn't correspond. No idea, other than a doubling of some sort. Nice job of making the overlay, Kurt!

Judging from the last overlay, a die clash seems unlikely, but what about a DDR? Can an overlay confirm the positions of these secondary features? To that end, I've created one more overlay using the same reverse photo without speculating on distortions which may happen in a double-hubbing--only rotation of the secondary reverse image. On this new overlay, I see many consistencies to the marks on this coin. Take a close look, keeping in mind that the secondary marks are doubled too. I've also included a clean reverse image if anyone would like to create their own overlay.   Edited by KurtS

Some very nice work there Kurt. I am quite sure you are perfectly correct about the DDR. When creating a die, the first blow from the transfer punch only created an imprint roughly 3/4 of the way out to the rim (which is why the 1933/2 overdate penny only shows the top of the 2 - the dies were created by one blow from a 1932 dated transfer punch and then two form a 1933 dated punch). I have some of these 1956Y pennies with the doubling at work. I'll have a look at them and see if they show all the details that you coin does. |

Thanks thesandpit--I guess I covered most details. And how interesting...thanks for the information on the 1933/2 overdate! That's a coin I'm trying to "noodle"--maybe at the next coin show. Yes--let me know how your 1956Y. compares to this one--thanks! Edited by KurtS

Hi Kurt, Great coin! The lettering shows characteristics of this one: http://triton.vg/P60-63.html theorized to be a triple punch (your "double nose" you're looking for  ). |

Xshift, exactly--the doubling and spread on that documented DDO strongly suggest a similar process at work here (imo) |

Yes the double nose. Here's my favourite one.  |

Beautiful toned penny--and very dramatic offset punch--thanks for showing that one; another I'm trying to "noodle".
Fortunately I have a good head for storing details....someday it will burst, lol.
