Is there a doubled-die error on this 1970-S LMC?

No. This is all machine doubling.

Next to my coin is the "doubled die". Could you explain what the differences are, please?

The image of the 1970 S DDO, on the left ( the very shiny one), was cropped to use in comparison.

This is a cropped image of "the doubled die DDO-001" from PCGS.com. Could you please explain the differences with the MD in the picture of my coin next to it? Also, does the "7" always look crocket on the DDO? Is that the way we can tell? Thank you very much. I am very new at this, and I really appreciate the help.

DD MD

First off, be careful using pics from sites, they may complain so it's best to put a link to their site/pics.

2 main things that are good clues:

The real one has extra width, it has the normal plus the second and both are raised not flat and shelf like into the normal image. The MD coin has normal width but a flat shelf in it from MD.

The mintmark on those older memorials was punched after the die was made so to have both doubled means that it would need to be a DDO plus an RPM in exactly the same direction so if you see the same shift on both then it's most likely MD, that only applies to ones like this where they punched the mintmark.

Here is another pic of my coin:

Also, I wanted to know what caused the "7" to be crocket on the DD image?

Because it's rotated, it made the date deformed like the 0 has the bulge going NE/up-right so the 7 has the same issue and the rotation probably shows best closest to the rim/away from the center just like if you rotate 2 circles the distance of rotation is longest the further out you go. So notice on liberty the doubling is going down and strongest on the L then the opposite side the date has the doubling going up strongest on the 0 because of that rotation.

See the listing on Coppercoins:

The 1 and 9 looks straighter. Is the second pic of my coin still showing MD? No MD on the mintmark of the DD at all ?

Yes, still MD. I also see some on the S but even if it didn't show there it's still MD, shelf-like and flat and into the normal design.
