Does anyone know what causes the indented ridges around the edges of both sides of this Peace dollar?

None of the letters that overlap into the ridge are crushed or bent at their ends (see images), like the ridge was in the planchet before it was struck.

Also, beyond the ridge the edge of the coin is beveled, angled sharply on both sides, not the usual shape.

I apologize if this is something simple or common.

It didn't seem like PMD to me. I would think PMD would cause the parts of the letters in the groove to be smashed.

Hmm does Ridge Ring occur on these large silver coins too?

My first thought was a worn die issue.

I'd take a peek here http://ec2-13-58-222-16.us-east-2.c.../1926-S_VAMs
Looks to be one of the Beveled die VAM's based on the front of her forehead...
Maybe 1R...?
cool coin!

I'd post her up on VAMWorld to get some expert opinions.
Look at those fat rays running through the LL's on the reverse and that MM.

cool coin!
smat

edit to include post her up on VAMWorld

Thank you for the suggestions and links.
I read through all the reference materials you provided. You nailed it, as usual. Here's my summary take away of all the materials you so generously shared as they relate to this Peace dollar.

Soft die errors (Brandmeister) result in both beveled areas (smat45), like the one at the forehead and the depressions around the edges. Soft dies have defective metal that's too weak and sinks.

Smat45 thanks for the insights, path forward, and enthusiasm! I am getting registered on Vamworld, and will post there too to get more input, as suggested.

Ridge Ring (Spence) caused by die deterioration/worn dies (Errers and Varietys, John) seems like an overlapping issue. It's not clear to me from what I read if Ridge Ring happens on normal dies, or only happens with defective "soft dies".

Given that most commonly die wear results in things like distortions, breaks, chips, and cracks, not sunken fields, mechanistically, I would guess that Ridge Ring is a type of soft die error. Counter to this conjecture, Error-Ref.com says, "The pattern of (soft die errors') deformation bears a passing resemblance to the "ridge rings" that frequently develop on copper-plated zinc cents."

Would love to understand what I'm missing if you experts care to share more.

My understanding of Ridge Ring is that it's basically a Die Deterioration problem. That deterioration will happen as the die ages. A soft die, being insufficiently hardened, will experience Die Deterioration at an accelerated rate.

I think the main difference in terminology between Ridge Ring and soft die is the location. The Ridge Ring is (somewhat obviously) a ring shaped ridge just inside the rim. The soft die errors seem to happen on the die face, where the surface metal retreats around and over the device cavities. When viewed on the struck coin, it looks like the coin metal is retreating around and under the devices.
