Basics of Double Dies

I think it comes down to intent.

Once the (defective) die is produced, the Mint intentionally put it into service, creating varieties. As opposed to a collar slippage during production is not normally intentional. ...jmho...Spark

I have an idea, use the numeral 2, as in 2 die. Everybody will be right, I think!

 

Man, that one flew by me so fast I barely read the words, let alone understand what you mean. Must be cognitive impairment on my part.

 

No impairment Robert, I was being a bit obstinate, sorry.

 

Isn't the Master Hub used to make the Master Die, the Master Die is used to make the Working Hub, and the Working Hub is used to make the Working Die?

 

We know quite a lot of them have trouble communicating intelligibly, so yes, that might be a problem. That’s one reason I think they rely so heavily on YouTube, it’s like an audiobook.

 

The way I learned for vintage coins was:

Master Hub makes Master Die.

Master Die makes several Working Hubs.

Each Working Hub makes the Working Dies used to strike coins.

Perhaps the modern process takes out a step.

 

But, Who's on first?

 

I could have written a book using references, ad nauseum, but most would click off, so brevity was my choice.

 

Why make it complicated for the beginner?

 

Well said. If I am learning to drive I don’t need a lesson on engine rebuilds. That time will come.... I understand why new collectors to the hobby are consumed by doubling. It’s likely the only thing they have an opportunity to find in their pocket change. For me anyway, it’s the least interesting part of this hobby. But it is different for everyone. I do find it mildly amusing how passionate we get when we try to lead a new collector down the right path. I would bet we scare off 70% of the fresh new collectors with the detailed information we lay on them sometimes.

 

Why publish incomplete information. Best to study up on the minting process before posting. I posted how it was done at the Mint for the majority of the years the Mint was making coins. Noticed I added that "things" may have changed in "MODERN" (after 1964 - post vintage coins) times so as not to Post something I was unsure of.

 

I would imagine that the 70% that we scare off are only concerned about the value of the coin that they found in pocket change. Nothing else!

A very bad example. How coins are made is as basic as THE TRAFFIC LAWS for new drivers. Learn 'em, or get killed or only ticketed if you are lucky.


PS In the video, it appears a CNC machine is making several HUBS. These are each used to make DIES. Therefore, the modern die making process appears to be much less complicated than previously used for vintage coins. They can make a hub any time they need one so it is not necessary to preserve a Master Hub or Master Die by limited use. That was the difference between "Master" and "Working" in the old days.

 

You have a point, however, I think a short explanation is sufficient to provide basic information regarding the subject even though a number of steps were omitted. If my short response about how coins receive a doubled image serves the purpose, I say great. If some want all the information as to how this occurs. they can search the web.

Does my post leave out paragraphs of details? Yes, because my intent was not to address every detail of every process involved in how a doubled image coin is produced. Rather, it was written as a basic understanding of how this happens. If I have erred by leaving out interim steps, it was intentionally done.

 

How about this then: When the die was made it was doubled in error and all the coins it makes will show this doubling. Now, I'll sit back and get bashed & trashed for all the stuff I left out by keeping it simple. Ah, what's a hub?

 

Good point. Answer: An explanation of that item, if you choose or post a site, book or article in its absence.

 

A "hub" can PROBABLY mean many things to different professions such as an airline hub.
In numismatics a hub is a "tool." From The Macmillian Encyclopedic Dictionary of Numismatics: A positive impression in steel of a design to be reproduced in reverse on a die.
Hubs have the coin's design raised in steel while dies have the same design sunk into the steel.

 

then you have hub doubling, also triple dies and quadruple dies (just bought one a dd0-05-fg-105 from errorsmostly on ebay for 56.00 at auction, he sells em for 79.00 nin too
