That is simply amazing! I can imagine that the "rush" must have been fantastic when you first viewed these specimens together.

 

Thanks for posting this!

Now that is very cool

[CaptHenway]

It was just incredible to see something that had never been seen before!

No grade on the die chunk?

[Coindude]

Wow! what a find. I'd bet Charmy would love to get her hands on that!

Freaking awesome! I am not much into errors, but that is one I can really appreciate.

Same here.

I noticed something. Tom says this discovery took place a few weeks ago. The coin and fragment are shown in an NGC multi coin holder that they stopped using over a year ago and which have only been available for bulk submissions for the year before that. So either NGC ignored their "no more multi-coin holders" decision, or they handled and slabbed this piece more than two years ago. (It definitely wasn't part of a bulk submission.)

[CaptHenway]

I asked our gracious hosts in advance if they could accomodate both the coin and the fragment, and Dave Camire said he would see what they could do. Obviously they used a leftover multi-coin holder, and did a smashing job at it!

Not a "casting" problem - die steel is not cast to shape.

 

It looks like a severe annealing defect in the die – likely poor tempering which made the die face brittle.

 

[CaptHenway]

At some point molten steel was cast into a form. At some later point a part of it became this die.

[RWB]

The molten steel was cast into a slab or ingot which was then hot rolled and formed into square-faced rods. Typically the mint purchased the rods, and machined them to initial working cylinders. (Much like using a wood lathe to make round chair legs.) Machining was done "across grain" of the steel so that the crystals lay parallel to the length of the die.

I love errors coins...That article got me so excited to know that there is still so much more out there to still be "discovered".

[johnny9434]

what an awesome thing to get and get slabbed as well. wtg

[TomB]

That's insane. Thank you for posting the thread as I would likely have never seen the article otherwise.

WoW I love this one!

This is SOOOOOOOOOOOOOOOOOOOOOO cool!

[RWB]

Regardless of the details, this is a fantastic error combination and an excellent article by Tom.

Hard to believe the anonymous collector held onto this raw error since 1975 ~uber coolness~

[CaptHenway]

The pieces have found a new home with a serious error collector.
