Looks like Mechanical doubling..
Not a Doubled Die variety IMHO

 

Thank you sir

 

Mechanical doubling on this Soviet era coin too?

 

Are you referring to the MD on the coin? If so, it's quite common, especially on proofs.

 

Nut... Proofs are double pressed, correct? If so, then this would increase the instance for MD?

Proof coins are "struck" at least 2 times . Please read:https://www.thesprucecrafts.com/strike-type-definition-768693

 

Proofs are struck twice but as the Die wears this happens, MD.

 

Nice photos - clear, crisp, close up -

See how the MD is 'shelf' doubling
compared to the main lettering/digit......
