That would show either sawing marks or split metal. It has to be one or the other.

I will brink back this because it is a very interesting post. Quote:
(1) the rolling process, (2) the blanking press and (3) the upsetting mill could have created or worsened a stress crack. I start with this to give my opinion: 1) Rolling process: Not really the roll of the metal can bend in the rolling process. The stress or de-crystallization of the material occur more due to a poor or lack of annealing. 2) The blanking press: Here yes, the blanking punches some times go out of the vertical, so will create a lateral forces. I already see some old coins pre- 1940 with angle cut. 3) Milling process: If was a milling process I do not thing we will have on this coin rim on the both sides of the split and why the milling process will push up one side of the split?

I think you're being far too dismissive I am not dismissive. Me I look at the coins from the point of view if could happened in the process of minting and what can cause the metal to react in that way. The KeepaChange show here many coins. Some I do not agree are legitimate. Some I congratulate to find. I am strait in what I see and give my opinion from my point of view. I do not look for prices like many others, just for coins process's and metallurgical field. |

The last edge shot is showing what looks like dental floss? Diamond paste and Dental floss.

that is my cats hair tbh,i cant get away from it....its everywhere,lol. I think that gunk is just gunk from years of catching crap in the crease overtime. I cant say for sure. But at the end of the day...i dont think we will ever actually know.....maybe ill send it in for attribution just to get some experts opinion on it by examining it inhand. Ill keep you guys posted if I do so

I'd send it in to Mike Diamond. I know you have asked him already. But having the coin in hand might show him something that images can't show.

I am sorry KeepAChange, this coin do not seem to me to be legitimate cracked planchet. Very nice photos, clear and I do not have a clue how you do 'it but superb. Like Coop say, to send to Diamond it is a very good option. By my side it is the lasts photos show me no fracture in the metal. There are some markers who tell me this, and one of the most important it is the Verdi's inside the crack and nothing outside. Second I do not see the de-crystallization of the metal. In the natural de-crystallization (crack) always we have parts which detached which it is not this case. There are more markers which tell me this: It is PMD intentionally done but for our security collecting community I will not say. Hope you do not pay to much for and can have a good return. |

@DEEZ, excellent photos which prove someone, somewhere fake crack coins and work more with war time because of the alloy composition which it is more instable to cold, heat and strike.

The one Deez posted is obvious PMD. The OP's coin is not so obvious. It would be nice if Mike could look at it in hand. I'm not convinced that it is PMD. |

I agree the OP coin it is not same like Deez post. BUT: why the Verdi's it is only inside? In normal condition will not be. This show as that the strike which could be see on the edge of the rim was done on cold condition and then the humidity developed after when the metal come back to the atmospheric temperature developed condense which facilitate the form of the Verdi but not to the rest. Like I say previously I can not disclosure methods the fakers use.
If Mike will have the coin in the hand will be great; also me I will like to have in my Lab.
And do not forgot: In the war time was use the shells to strike the coins. Those shells contain also ferrous metal which come from the shell caps.

I still think it is a cracked planchet even after all this.

I still think it is cut by someone to look like an error.
