Looks MD to me, IMHO. However, is it possible for the word "half" devices moved North, but "dollar" devices moved East, a true possibility during the strike?

Machine Doubling is so common on Kennedy reverses that it must first be ruled out

Thanks all. It looked like md but I had to ask because it didn't look normal. I thought something else may be occurring. I guess not

Machine Doubling happens on doubled dies as well. On proof coins Machine Doubling can affect the first strike and during the second strike of the proof coin, the first Machine Doubling can be flattened and it makes the fields look strange. But it is flat field doubling:

Note the fields on this coin? That flat field doubling is not part of the doubled, just as on this coin the Machine Doubling is not part of the doubled die. The Machine Doubling happened after the strike. (Just like normal and Doubled dies can be altered) But Machine Doubling is not a doubled die. On the doubled areas on the die, strike doubled die coins. A doubled die and a normal die are hub the hub processes. Machine Doubling is a post strike issue, and has nothing to do with dies. Machine Doubling damages the coin coming up post strike. Not part of the doubled die/normal die. Machine issue, not a die issue.

CoopHome: What is the difference between a doubled die and Machine Doubling? Machine Doubling is part of the striking of the machine. a doubled die is created on the die. thus the Machine Doubling is never a doubled die, as the doubling is on the die, not created by the machine.

First of all, I see no evidence of a DDR in any of your photos of the 73D. The 74D DDR-001 is not a good example to use for justifying your 73D as a DDR. The 74D DDR-001 that James Wiles used on Variety Vista is a very good example of a DDR and MDD on the same half dollar, read his description of the 74D DDO-001. Attached is a good photo of the 74 DDR in my collection, note the notching on the ER of AMERICA and stars under.

On the last image, you can see hub doubling on the stars. But on the devices that is Machine Doubling. So you could have both, Machine Doubling on a doubled die. But on the AMERICA that is Machine Doubling.

I agree that we can have MD and DDO or DDR. On Atrox example I see also doubling on the letters on right side and in the left MD. The stars are obviously hub doubling.

Thanks COOP to mention this because the post was pass without this mention which it is very important on recognize the doubling in the halves stars.

Thanks again everyone for your insight. I'm no doubled die expert that's why I wanted to see what others here thought. Being from the previous year and same mint I thought there may be a chance these were identical. I do see the flat field doubling and with it going this way and that way I was thinking maybe there's some rotation going on. I'm not seeing the notching as with most Kennedy halves but it may or may not be there. Using what I've learned doesn't always apply. Fundamentally when you see something listed on VV then that's what to look for. Looks like I've made another rookie mistake but it's another lesson learned. Thanks for the info

Thanks silviosi. I did check out dd first thinking what I was looking at was probably on the minor side but couldn't find the ddrs so I went on vv and saw what I thought at the time was a comparable 74 D. I've never looked at a Kennedy doubled die in hand so I don't know if the notching is visible without a scope
