Btw (and this is not a judgement of this thread but a point of order) this is how one claps with one hand. :-)  |

The blank one does appear marginally larger than the normal 1920.  Coin doesn't seem to be round, rim on obverse very flat and width varies, metal seems like it's been pressed from high areas into low areas on the obverse and not just sanded off - how does somebody do that?  |

It will be interesting to hear what SPP Ottawa thinks once he's able to see the coin with his own eyes. Please do post back with results.

how does somebody do that? Good question..sooo I had to find out. Here's my quick made in 10 min version. I'm not saying the OPs coin is PMD that is yet to be determined and I look forward to hearing about it as well. What you see here is just an experiment.    |

I am skeptical for many of the reasons that others have stated, but also because of the amount of wear. A coin with such an obvious error would be snatched out of circulation even by non collectors. Yet this coin has seen many many years of wear.

Wow @pennyman007, you got the oblong appearance and everything. So, how did _you_ do it? It's been 40+ years since I put a coin in a vice and tortured it.

Come on now Kbbpll lets allow Rocky (OP) to go to the coin show with some enthusiasm. He might have an unusual uniface strike of some kind.

well, something I need to ask. what do the dies sit on, ie what is the next surface the coin would be against if the die was missing. if smooth,i could see this being in that setup, no collar.

^ now there's someone that is thinking before randomly dismissing an error.

gunnern, we are not "not thinking" before dismissing an error. It's just that it is impossible for only one die to strike an uniface coin. wazzapening, a diagram for you. The obverse die for Canadian pennies is the hammer die. How is it possible that the impression of the die is struck on the planchet, if there is nothing to press down on it and make the metal flow?  Remember that the planchet is a plain metal disk. When the hammer die presses down on the planchet, the collar keeps the coin from expanding beyond a set diameter. The metal has nowhere else to go, so it flows in to fill the recesses in the die. The metal won't flow unless there's pressure applied to it, and in this case it is provided by the hammer die. (You can try doing this yourself if you have some play-doh and a couple of moulds.) If it was a true uniface strike, I think it would have been picked out of circulation quickly. People pick one-side-sanded-off coins out of circulation all the time thinking it is an error. Also, a full uniface strike, where two planchets are fed into the striking chamber at once, will have an abnormally strong strike with finning around the rim, which I'm not seeing on this penny. |

thank you so much for the diagram . very well done SlurExe97.when I show this coin to SFF at the show, he will see something about the copper very quickly .I had this coin in the hands of a couple of dealers at a show. you guys would be shocked to know what they offered me right there on the spot. just looking at it with a louper. them they started to out bid one another. I said look sorry, I am not interested in selling this right know. so what did they see that made it so interesting .I know what it is and after looking SFF coins . I know he will see it very quickly. as anyone that handles it and looks at the unstruck side

Not to mention the fact that even if the die were missing whatever holds the die in place for striking would certainly be bigger than the die and would hit the collar, not to mention the fact that there's probably not even enough reach before it would have to retract again.

Your welcome rocky.
If I can make one the mint can make one..lol. Even if it somehow found its way out the proverbial "back door" it would still be a mint error.
Thats why the experts need to have a good look.
