How Strong is this Die Rotation and is it Rare?

Indian cent proof with what appears to be die rotation. At what degree is it, and is this considered scarce or rare on these coins?

One is 135 degrees and the other is 170 degrees....Both are listed at an R-4 rarity factor.

At least, for the ones I have seen.....I can't really speak about rotated coins other than Ikes.

P.S. PCGS also charges $40 and NGC charges less than $15...maybe that is the difference?
