What would you call this, and how did it get there?

[belg_jos]

I've been studying this type for a couple of months now, and this one is the biggest mystery so far.

 

 

The pictures are very poor, but they still help to explain what I see.

On both sides there is something that looks like die damage. I have more dramatic examples than this, but this is one of the coins, which has it on both sides, on the corresponding place. If you would drill a hole there, you would drill through both. I have made the following picture to show what I mean. Keep in mind that this coin is minted in coin alignment.

 

 

 

I have absolutely no explanation for this. It is something that damaged the dies, but why did this happen on the exact same corresponding place?

 

I have found similar things on two other dates, on other places. And I have from every date more than one example. So a corrosion-bubble, or something like that is out of the case.

 

Anyone here, who can solve this mystery?

If I had to make a guess, I would say something harder than the die got struck into the dies without a coin blank in the way to keep it off the other side. In other words, the dies come down, no coin enters, but a steek shard makes its way between them before they close all the way, and BAM, a two die gouge.

And that Crown is a cracking too Neat little late date die crack.

My thoughts exactly, Vfox.

Yes, that's the only way something like this could have happened. The question remains where this hard material comes from. A die chip could be an explanation, but if a die is chipping, it is bound to be taken out of production. On the other hand, I have more than one coin, that is struck with that die, so that might not be the source of that chunk of metal.

 

Thanks for you replies
