What did you use to get a 9600X9600 resolution?

This was done with Stack and Stitch technique:
Canon T2i
Nikon 2x lens
Panorama of 6 images, 2 wide x 3 tall
Each of 6 images requires 10 stacked images for depth of field (Total 60 images)
The 2 x 3 panorama is logical because it comes out square (for sensors that are 3:2 aspect ratio), so fits the coin nicely.

Amazing photos! I am trying to learn coin photography and you have really set the bar for this newbie!

Thanks Teresa61! This technique is not for the faint hearted. But there are other much simpler ways to shoot coins that result in very nice image quality. BTW, my first Stack and Stitch image was a 3x4 panorama, 12500 x 12500 (156MP). See it here: https://easyzoom.com/image/123994I found that the extra resolution was a lot more work for just a bit more benefit, so for all the rest of my panoramas I've stuck with 2x3.

Amazing looking pics.
How long did it take to stich and stack the images?

Thanks Dar.
Each of these takes about 20-30 min of work to shoot, stack, stitch, and upload.

Those pictures are crazy good and the technology is mind-boggling. I was reading the link you sent about Stack and Stitching. As a software developer, I am truly impressed at the concept of taking multiple images with different depth of focus and afterwards stitching together the in-focus portions of each shot to get a composite photo showing the best detail.
Who thinks of this stuff? Just spectacular!

Amazing detail, would the 20-30 minutes be slashed if there was some way to automate the process? Would extra dollars for the setup solve the time problem or not?

Problem is the work is done in several different programs:
Shots are taken with an automated XYZ system
Shots are converted from RAW to TIFF in editing program
Shots are then stacked with a stacking program
The output images from the stacking program are stitched together with a stitching program
So while each step is automated, there is no single program that controls the whole process. Also, there are some creative decisions needing to be made during the RAW to TIFF conversion, and during the stitching process, and these cannot be easily automated. I suppose the whole thing could be automated, with some sort of shell program that would call each of the sub-programs, plus some AI that could shoot for various creative targets in the output (if they can be objectively determined), but I would expect that software to be very expensive to develop.
