I think just about everybody likes a good Doubled Die. A problem for many people is distinguishing them from lesser anomalies. Another problem is distinguishing the nine different types of Doubled Dies. To solve both problems, an understanding of the minting processes is necessary. There are several websites and books available to acquire this information, and I strongly recommend reading them, as I have to help with this post. My intent here is not to replace the valuable and in depth information they contain, but to make available some of the highlights and what I consider to be the most important information in an easily accessed and brief format.

The "lesser anomalies" I mentioned, is the first thing most entry level numismatists learn to distinguish. In my opinion, they can be lumped into four major categories:
1. Strike Doubling AKA Machine Doubling (MD), is the result of the die making contact more than once, altering the initial devices. It usually reduces the size of the initial devices by leaving a flattened edge with a different color.

2. Die Wear is when the die has recesses on it that are transferred to coins as raised areas. They are usually alongside or near the devices and without the crisp edges of normal devices.

3. Damage is anything that happens to a coin after it's been minted. It's usually recessed in the coin.

4. Minor Errors are "lesser anomalies" only as they relate to Doubled Dies and major errors. They stem from damage on dies, and include clashes, chips, cracks, etc. They are valued less than major varieties and errors, but highly collected.

There are variations in the four categories, but as I said, I'm trying to present as much information as possible while remaining brief. That being said, here are my Doubled Die E-Files. Anyone can use them on here, but please wait a few days before copying them, as corrections may be necessary.

Coinmasters, thank you for this valuable information along with excellent photos.
As of today my One area of uncertainty still is to distinguish the difference between the Hub doubling and, MDD, WHO.

Great presentation and information CoinMasters! You remind me a lot like Coop in a good way. This will serve a good thread for new members that are new at the coin collecting hobby. Knowing the Minting process as well is good, since you'll be able to understand the terms better and know how the errors occur. Thank you for this awesome and very informative thread! It was a interesting read and learned more as well! You are very good at this.
Errers and Varietys.

Your welcome Chase, I think that's an ongoing story for most of us. It gets better with time.
Thanks EandV, I did my best. I'm glad I remind you a lot like Coop, I'm glad it's not in the bad way. lol I'm glad you picked up some things form the thread, I think we never stop learning.

There could be a thread for each of these classes of doubled dies.

CoinMasters, Some good pointers on a subject I'm constantly having to reference back on.

Though I understand the hierarchy of how and why. I have not gotten all the years memorized like those who have seen so many more than myself. I'm constantly having to look up or back for known references.

The way I look at it is, master hub doubling and or master die doubling are hub doubling on a larger scale. Follow coops illustration below that shows it better than I can explain it. See the trickle down effect that makes one level produce so many and another level so few.

Also remember a separate or different doubled die can show along with master hub or master die doubling. Thanks, Doug.

Yep there could be Coop, but don't give me any ideas. As brief as this one is, it took me forever. Is there a way to make all these E-Files smaller?
Yes it takes a lot of memory Halo, and something about repetition, but I can't remember what. Coop's die diagram was my inspiration for this one.

There is some great info here. I still have not totally grasped the full understanding of how our coins come to be so I go back to so many of these types of posts time and time again.

@uruman if you read this CM has used the 1963 DDO example you just got :)

On class V doubling the pivot point can be anywhere on the coin not necessarily by the rim. And class I doubling is actually a special case of class V doubling where the pivot point is at the center of the die.
