Question regarding identical marks on multiple coins

ShinyThingsInPM

I have a number of the same 2006-W burnished "W" $25 Plats that have identical marks on them

6 coins have identical frost breaks in exactly the same position - two on obverse and one on reverse

Is this an indication of the same set of dies used?

If it is - would it affect the grade since it's not post-strike damage?

Thanks for the feedback

Since these are frost breaks on proofs I think that yes it will affect the grade. Even though striking flaws you will not get 70 grades on them.
And is it worth the trouble to grade PR69DCAM's is now your question.

I'll add that it does sound like the same die.
