Planchet error or PMD?

[ChrisHagen-migration]

I was just sorting through hundreds of these Danish 10-øre coins from the 70s and 80s, and I came upon this one. I can tell two die cracks I believe, as well as what seems to be a strange sort of planchet error or minting error that chopped off part of the coin. The other side of the coin has a strange edge in that area, but even in hand under magnification it's hard to see.

 

I can't see any tool marks on the coin, or any indication that it was held in a vise.

 

Here is a link to an imgur album with the best pictures I could get - a camera and a little tweezer thingy for removing splinters. (Don't worry, I was careful to avoid scratching the coin!)

 

What's your take on this? Post-mint damage, planchet error, minting error?

That big piece of metal along the perimeter looks like a serious die break (vernacular, a "cud"). I think I see a faint crack on the coin, too. Those will very typically come off the rim. When they're not off the rim, they're retained cracks.

 

I have a few Danish coins. These are lovely coins.

Oh it's not an extra piece of metal, it's a huge missing piece of metal along the rim!

 

Thanks for confirming the crack, if you can see it from my horrible pictures then I am probably correct in seeing it coin-in-hand.

Chris, is it raised on the coin? If it is, it was depressed on the die, due to a break in the die. That's how these die breaks manifest on coins.

 

Anyway, on the light crack, let's say your photography was good enough, I could see it.

No, it is not raised in the coin. The pictures must be causing some kind of optic illusion, like when pictures of craters look like raised mounds. There is a large chunk of metal missing from the coin, no raised part.

 

Edit: hold on one minute, taking some more pictures

 

Here are some more pictures. The die cracks actually show BETTER in these than in my magnifying lens photos. Hilarious.

Pictures!

I think it is a planchet flaw.

Thanks a lot for your input Conder!
