1943-S Lincoln Cent, RPM-007?

[foxpigsquid]

Feeling fairly confident this is an example of RPM-007 based on comparisons against:

* http://varietyvista.com/02a%20LC%20R...943SRPM007.htm
* https://www.coppercoins.com/lincoln/...&die_state=mds

However, a few documented markers are faint or missing - the die crack across the shoulder to the lapel is only barely visible in just the right lighting (which I was unable to capture but does match the descriptors above) and on the reverse there is no die crack on the upper right wheat stalk nor northwest from the N in ONE. Being somewhat new to this, I'm guessing it's either not 007, or is 007 but a slightly earlier die stage, or given the aggressive die polish lines visible, a later stage in which they tried to repair?

During this afternoon's online treasure hunt, I was surprised at how many different RPM varieties exist for 43S (and again being newish here, that may be the norm for a coin with a mintage nearing 200M?). It's also interesting that the 43 D/D is recognized by the big three but only ANACS attributes the 43 S/S. Though the D/D is much more obvious and therefore likely much more collectible

yours can't be 7 because of MM position.

i'd need a clearer image but i'm kinda leaning towards new tbh. (i'm not 100% sure that inner part of the upper loop is an rpm as i do see some "damage?" in that same area)

i'll do some more investigating.

the top tpg generally go by FS numbers for listings for stuff like this. there really are a decent amount of varieties out there not given FS numbers that probably should be based on current listings.

Dang, thought I found a match. The zoomed image is at the limits of my current setup (and that took some patience to get the lighting and focus as 'good' as it is). I tried to highlight what I see as splits in the MM if that helps. The die cracks that are there do match well with 7 but I can see now that the position does not. After 80 years, I figured a new variety wasn't realistic.

your images are pretty good albeit usually a little overexposed but sometimes we just need professional-level images to give a professional-level opinion and we do try to be as accurate as possible but w/o the coin in-hand...

my previous dslr nikon with a micro zoom (whatever it is called) 150mm could get into those hard to reach places very well but i did have to get as much of the area in question into the field of view as possible, meaning i couldn't see any of the rest of the coin, SO, that the area in question in the image could be enlarged quite a bit w/o getting pixelation too easily.

my former camera was good to be sure as well as the lens (had professional help picking them out) but they were not top-level and it could still produce exceptional quality (imo) full images and close-ups but that also included doing post-processing work. basically zooming and cropping. not much tinkering with contrast/lighting/shadows/histogram etc. usually.

i would just recommend submitting your coin for possible listing but i'm just not sure if the mm is an rpm. there is something going on but...

i will also say this forum is good as well as the software BUT it is notoriously bad at not allowing uploading of larger size images (kb/mb 960x1408) for good reason tho.

your images MAY be actually good enough to enlarge but we can't get our hands on them vis a vis this forum. you'll have to provide a zoomed in image of the MM (ONLY) and not edit the image in any way, so the size will prob be a few MB but you'll need to host it elsewhere and provide a link to it here, or just submit your coin (preferably with others to reduce per-coin cost/expese).

IF you get good at post-processing (ain't too hard imo) you can do something like this. under 1MB but much bigger (in dimensions ) than my usual image upload. for my part i'd need an image with not arrows/lines etc like this or maybe someone else here can do something with your current images that i can't?

Morning foxpigsquid,
The first issue we have is both photo's are slighly turned. If you have a photo processing program use the straiten tool to line up the very top of the date.
I tried to copy Dr. Wiles's photo, then rotate the photo to horizontal. Then I had to do the exact same thing to your photo. Which required about 20 min of time on my end. Everyone needs to make sure there photo's are horizontal to the plane.
OCCnumis is correct this cannot be RPM007 - see overlay.

My response would be the same response Dr. Wiles had given me many times I sent a coin in. Do you have a second copy to verify this could be a variety?
If you do then your chances are better. I may/may not be able to see part of the curve above the top loop of the primary but that means another type of overlay will be needed.

Thanks all for the guidance. Straightening the image and applying the overlay method in particular is something I should have tried with the documented RPM examples before posting my 'educated' guess - doh. This is the only 43-S I own but it's a point well taken.

I've been making due with extension tubes on the 400mm lens I use for wildlife & sports to reduce its minimum focal distance, which works well for whole-coin images to catalog my collection, but if I want to delve into this detailed world of the hobby I need to look into a dedicated macro lens - that S MM photo occnumis2021 is phenomenal. Trying to research & attribute at this level using pixelated digital zooms just doesn't work.

[occnumis2021]

feel free to upload a close up of your best work and post a link to the unedited image. i can tell you a lot at that point. (not raw format please)

[foxpigsquid]

Rigged a 10x loupe into the focal path and could focus well enough to capture these of the MM alone. It's no dedicated macro lens by any means but it is a much closer (mostly in focus) look with slightly varied lighting between the two.

Overlaying existing RPM examples from the links above, none match spot on (005 is close) so maybe this is just a normal 43S with an odd MM -- the horn off the top of the spine of the S is what caught my eye. Thanks again all for the continued time & insight.
