1977 dime no ridges. Pmd?

[Ammoman]

I suspect this dime had the ridges removed post mint.
I’m not sure why someone would do that but I
Figured I would check with people who know more than I do on things like this.



Let me know if this dime needs to go back into circulation.

Thank you for your opinion!

PMD, dryer rolling damage. I seen over the years several, return to the wild.
