That is also showing machine damage. Note, that device is not thicker, but thinner. Compare it with the first 'T' on STATE and you will see that is true.
Note on every 'T' on the UNITED images I posted the upper bar is affected upward in varying degrees according to the spread of the coin.

I went to the site Brians varieties site that has a bunch of different years of double die nickels and there is a lot of ones that don't look anything like your examples and I even found a couple that showed the doubling line running half way down,i am not saying this isn't from a worn die but why the separation line? Why the notching on the letters? Not something that I have seen on a worn die before.

I know my pictures are not the best but after I upload them to the optimizer then down load them back to my phone then upload them to the site they break down and get fuzzy so nothing I can do about the pictures,someone told me I wasn't holding the phone still so I made something to hold the phone and that didn't help.

On the MD example I posted above: Note the bottom of the 'N'? It looks like there is notching there? But will all the rest of the MD on the other devices, it is all MD. Note on all the same left foot of the 'N' in the other images. All are taller except one, that is not part of the area hub doubled happened. Hub doubling rarely affects just one device. (I've found a couple that were that way, but they are very minor)

Your picture of md shows the doubling as flat and the doubling lines on my picture is round,i am not used to looking at nickels.I found a homestead quarter,it is one of the double dies that the doubling is in the window it is a small line but if it wasn't listed as a double die how many would think MD.

So MD on a nickel can show rounded and not flat like I said never seen this type on a penny and that is what I look at the most

Kevin, the same principals apply to all denominations. There are different types of worthless doublings, all are encompassed in Strike Doubling. Strike Doubling, in the purest sense, is an extra strike after the intended strike. It strikes part of the device made by the first strike; in so doing, it changes the device, reducing it's original size which is replaced by "doubling". The doubling is on one side of the original device and is flat, and approximately 1/2 the height (from the field), of the original device. There you have Strike Doubling. Strike Doubling, in recent years, has been expanded to encompass other forms of worthless doubling that occurs at the time of the strike, but only requires one strike. MD (Machine Damage), is generally the result of wear on the die, producing "doubling" on one side, or two or three sides, or all around, or even some distance from the device. There are nine forms of genuine Die Doubling. They all originate on the die, and require only one strike. The most valuable and sought after, is depicted here in one of Coop's pictures. The famous 1955 penny has a wider spread, but of this same type.  I figure you probably knew most of what I have written, I just hope now you can see how the "doubling" on your coin doesn't necessarily have to appear rounded or flat. |

Actually is just one strike (proof coins are struck 2 or more times) On the business strike cents, a die movement or bounce alters the coin after the strike. Movement by the machine, dies or bounce. Just one strike. The movement can be in two directions from the same single strike making what some call triple Machine Doubling. But it all happens on a single strike on business strike coins. On proof coins the second strike can create field doubling. (a distortion of the devices, that move the metal at the field level of the devices.        The happen mostly on proof coins because of the second or more strikes that are needed for the detail proof coins should have. But on other areas on the flat field damaged coins, there is also machine damage on other devices that doesn't touch the field like the images above. It is like the normal MD we see on other coins.   This is on proof coins where you can have both. MD and Flat field doubling. |

Sounds to me like proof coins are in double jeopardy.

Maybe so CC. But they are my favorite on the pre frosted coin era. So I like 1960-1964 proof cents and nickels to search.
