I found this 1974 D lincoln cent with what appears to be doubling on the reverse and obverse ... Specifically the the 7 in the date looks like it has a very pronounced notch at the bottom and then on the reverse lincoln steps and the arms as well as the armrest look boldly Doubled . Oh ... And please excuse theses grainy photos for now my good phone broke so I had to use my cheap one in the meantime .
I've never knew that notches and that sort of raised doubling could be machine doubling that's an amazing observation you have ... LOL
WOW! Again with the blinding detail. I see doubling but I guess that's what everyone seems to call MD.
Wow ... And I never knew that showing detailed photos is a bad thing if your examining coins to determine if they're doubled dies .
The Lincoln is so small on the reverse inside the Memorial, that even if there were doubling, if it takes a microscope to see it, I don't believe it would be of any significance.
Looks like MD to me especially since the mm has the flat shelf along the top. The notch at the bottom of the 7 looks like true DDO but I also know that light can play tricks on the eyes. Without being able to tilt it in hand it is hard to say. I do believe there are examples of DDO coins with MD on them.
I wasn't trying to knock you showing your photos, rather complimenting your photographic skills. See this is the problem with reading other people's text. No need for the headbanging though. I meant it as a compliment. Sorry you misinterpreted it.
There is a difference between magnification and resolution. High magnification doesn't mean a photo is detailed, Higher resolution does. Electronic magnification is the baine of resolution as the software involved adds "imaginary" pixels between real ones as to not offend the user and any small variation can be portrayed as raised or split or flat when it really isn't. There are 8 classes ( ways) of true doubled dies and a 9th ( Not even God knows how) for single squeeze stuff they call a doubled die which really can't be a doubled die). If a person is going to spend a lot of time and interest on this I highly recommend: https://www.amazon.com/Authoritative-Reference-Lincoln-Cents/dp/B0032CLWQE/ It is well worth the money. Jim
A single doubling can rarely be there only. It can be the focus of a pivot point, but generally there is more doubling around it, so one can not just call a coin a doubled die from one point you have to take in consideration the surrounding areas that need to confirm the same type of doubling : deterioration, true, machine, etc. Well, I strongly disagree there as it is unknown as to how much was false pixels from the magnification.

Have you ever zoomed in on a digital picture and it got all pixelated and hard to discern anything ? Software, can make all that look better. So when ppl use those microscopes they can make things appear that are not there. There are many threads here where people see numbers, faces, etc from nowhere when they use microscopes and other things where the software will "correct" images. You want to use a mechanical zoom, and not an electronic zoom. AND when you convert an image to JPEG (which may or may not be automatic) or anything else you do not want to use sharpening, and other features. Those will just "add" things to the image to make it look better .. which makes analysis all but worthless.
To try and give an illustration, I went back about 8-10 years and found a similar photo of mine that was taken with a Canon point and Shoot that was a 5mpixel camera , but this photo was shot through the eyepiece of a dissecting type of microscope @ 10X glass lens, you can see the pixels , but the image is sharp because the actual magnification was done outside the camera. So extension tubes, bellows, accessory close up lens, etc. can produce satisfactory photos without excess pixelation rather than trying to make a 3-5mp USB microscope ( even though it says 100X) show the same details. Jim This was to show a diagnostic chip near a cent wheat stalk.
I have had bunch of this 1974 D LD and SD in the UC and AU condition, most of them has the 7 with a notch same like this. First I though I got it but after went thru all these same coins they all came out like that identically under USB Scope. Even in the reverse you will see ABE dd. I might be wrong but that was my experience.
Yes you are correct there are actually Doubled Die coins that do have MD on them ... Not saying that this is one of them since it's hard to tell . But Im sure that I will know soon enough
So I noticed that no one said anything about the Doubled arms and Doubled steps ... Nor has anyone said anything about the pole under LINCOLN'S right hand which is visibly Doubled as well
Once I get a better phone I can take better pictures but unfortunately Im stuck with this one for now unless I take another picture from the pictures off my other phone ... Oh and I do understand how pictures can sometimes be distorted but fortunately that isn't the case with any of my photos because once the pixels start becoming visibly too distorted I simply won't use the pics since I'm not trying to mislead anyone .... Infact I'm actually using a camera attachment that's specifically designed for this purpose. But either way I'll still take some more photos using my other phone so that way everyone can actually see that it's not the megapixel throwing shadows if that helps
