Here's a D/D/D that came from the same roll as the Machine Damage Doubling I showed earlier. This is a minor RPM, and mainly shows up on the serifs, but when shot in High Resolution a lot more detail shows up and makes it more interesting.

Wow!! Great pictures, but I do not see a triple D.... Cheers, RickO
Man, forget the tripling. I love those pictures. It's like a scanning electron microscope! 👍🏻 👍🏻

This is the photo quality that CPG needs!

Arrows at the three sets of tips. Looks like it took three shots to get the angle of the mint mark correct.

@ChrisH821... Thanks, missed the top portion... The bottom looked more like a double with a chip.... But the top is clear. Cheers, RickO
Great photos.
Certainly appears to be what you say it is. But I think I'd rather have the photos than the coin.
Wow! Those are some great pictures.
Can you please post details about those pics? What scope, lighting etc?
Please?
Wonderful images... would like to know more about you set up.
never mind. I just saw!

Just think of the amount of pareidolia emeraldATV & RobertLahti could see with a photo set up like this.
This image required 50 sub-images taken at 6.25um spacing. In theory this could be done manually using a micrometer Z-stage which has 10um increments by approximating the middle of each increment to shoot 63 sub-images at ~5um steps. If you are only interested in 2D and not the 3D renderings, then you could probably go with 10um steps and 32 images.
The problem is that it's very tedious to manually shoot so many images in such small increments. Because of this, I use an automated rail that can make steps as small as 1um. I just have to set the start and stop points, enter number of shots, and press "go".

Awesome photography! Very impressive!
The sad thing is, that's EXACTLY what I thought when I saw those photos.
What brand of camera? Hubble?
Hah! But alas, just a Sony. I usually recommend Canon cameras because of their electronic shutters, but later Sony cameras also have this functionality, though they are more expensive.
