i think I do see where the nine is reduced but I don't understand about flattened devices. I thought that was just wear. devices are the numbers not the doubling correct? I need to be concerned about flattened numbers?

The doubling part that you see is flat and not rounded like a true double would be. So he is saying the doubled part which is from MD is flat and shelf like. The devices would be the numbers yes or any of the features of the coin. Coop usually has a good picture of MD vs Doube Die you can also go to http://doubleddie.com/144822.html to see |

Coop should be along with some superb pictures to explain better.
That is not a doubled die, though.

thanks for clearing that up for me. I am not a quick learner but I will learn. kurdlezuit meant well I'm sure but it threw me for a loop when he said the devices were flattened.

Here is a side by side of MD-Normal-Doubled die.  Note the overall shape of the MD-Normal. They are both the same over all size, but the MD is damage from die movement during the strike. So the die is normal and the machine created the damage that you are seeing. But not the hub doubled, double die in the third image. Note how the device is doubled? That is not during the strike, but on the die it self. Thus the term doubled die. |

the doubled die and the normal are clear to me. so the die moves, creating md also known as Strike Doubling. am I correct in assuming that as the die moves it causes die flow that in turn causes md? and also the later the die stage the more pronounced the md? I truly appreciate your time and patience mr. cooper. |

Die flow is die wear on the dies. The die ages and show it wrinkles that way with the die flow and weakening devices as it ages.

@coinmasters,If you are asking what can make the MD and not a Worn Die Doubling which has a few types.
The MD the Die moves/loose as the coin is struck. Strong MD this is more extreme and not very strong MD much less extreme.
John Wexler site can set you up with best info on about 5 or so different types of Doubling type happenings to Coinage.
As Cooper has said before the Big the coin the more this MD happens. I search Kennedy's at times and MD is a running happening find. 2 out of 20 maybe more or less MD.
