1951-D/S OMM 001; LDB4-002 with possible DDO in question.

They are better. It looks like a split serif rpm. There may be some slight separation of the Ds on the curve of the D about 3 o'clock.

Photos can take a long long time to get right. I use two lights with led bulbs, brightest white I could find. I drape a cloth folded four times over the 10x 20x 40x 80x Amscope microscope with a 14 or 16 megapixel microscope camera and even with decades of experience, lighting is the number one frustration point with me. I can touch or pull a bit on the cloth and lighting changes. Some times on a whim, I sling lights at weird angles and peer into the eye piece and start laughing. That impromptu chaotic light setup produces a decent photo.

Over the past year or so, I sold all the OMMs (1951 D/S, 1946 S/D, 1944 D/S) I had, and I did not have a good photo saved for the 1951 D over S. To tell you the truth, the 1951 wasn't one of my favorites, so I just let it go.

Look your three 1951 D coins over, do they have the same type scratches below the first 1 in the date ?
It so, then theses coins could have easily came from the same die. I am still looking over the ddo aspect of this, I will need another day or so. I was sort of under the weather today ( Thursday) . Tomorrow, our weather is not going to be pretty here in Virginia, so I will respond when I can.

Going through the RPMs on varietyvista, and looking to see mintmark placement wise, could there be any matches.

1951 D Coneca RPM 006 might fit. This one might be a tad too high for the mintmark. Although the inner part of the D appears a lot stronger on the varietyvista example. It has that inner portion of the D that could confuse people on whether an S could be hiding under a D.

Additional RPMs that might match in reference to the mintmark placement are:
011
019
025
034
037

It's early. Again, breakfast calls.

As for the doubled die obverse, does the notching resemble this ?

The mint mark placement on the variety vista example, versus your coin is pretty close. Stomach wants food.

Gary Kozera,

Your knowledge, time and helpful resources are highly appreciated!


*After studying the above educational links
and careful examination of coin in question… there’s definitely some PMD OR MMD; However, there is also clear notching (split serifs) with “cookie cutter” lines, & added thickness to many of the letters in the motto and ‘Liberty” (most prominently visible on “I” & “R”). In addition, the mint mark has what looks like a “peekaboo” serif NE and possibly SW.

What are the odds this could be a new variety coin (unlisted) and what is the best way to confirm if coin is, in fact, a DDO and/or OMM?

Please see additional pictures in above post and advise. As always, thank you for your time and consideration.

Best,
-Meagan

The best place to start with this sort of attribution is hit the main forum page on the top of the page here.
Go to CONECA services and add a post in the attribution section. Only the staff at CONECA and you should be able to see it.
I STRONGLY suggest that you add in every possible question and any additional photos you'd like in the first post.

It may take some time before they go through all the new posts and eventually find your post a second time. Believe me, it will take some time the second time around.

You could link this post there, which may be good enough. If they do not respond in a timely manner, then you can ping the CONECA president Jamez (yes his username ends with a Z) and he should get back to you asap.
