1969-S DD? Need A Few Opinions On This Please.

You have an example of what some call Machine Doubling. I call it machine damaged. After the strike is complete, on the way up from the strike, the die movement damages the devices. How the base of the device is wide and up partway you can see where the die movement reduced the devices. The date and mint mark affected in the same direction. This is not a doubled die or a RPM as the die was normal, but the devices were damaged after the strike. On a doubled die the doubling is on the die making the devices wider than normal. Same for a RPM, the punching of the mint mark is enlarged in a different way. On a RPM it is the mint mark punch that makes the mint mark and when it is miss punched to may see a spread between the punching. Here is a set of images to help you see what you have:

Note the image in the center? That is what a normal strike would leave. After the strike if the die moves it damages the device, reducing the size of that device. Just like the image on the left of the one I posted. And the image on the right is showing a known doubled die. You can see how that device is enlarged. That is because the doubling was created on the die by the hub that made that die. Thus the term doubled die, means they doubling is on the die. Your coin was from a normal die, but damaged by the machine after the strike. Hope this helps. Welcome.

Cujohn.You can get way better than that. I have found one where three quarters of the device is reduced, because the die bounced three times!! I'd call that machine tripling. Also, to the OP, If you had a Doubled die, normally you wont see a spread on the mintmark too because the mintmark was punched in after the hubbing process until 1990

The 1968-1972 cents have a lot of MD coins in them.

Here is the coin I started this whole forum with, very strong
