The "R" seems to have a small dot or smudge in it. And the two pence just looks like over-inking to me.
I'll echo that, the "R' does seem to me to have a scratch, but it's like often say here.
"Imagine getting a diamond appraised from the back of the shop"
Sideface varieties need "In your face" close up scans, to accurately appraise.
This is how "Best practice" sideface identification should be presented
A scan of the stamp, as clear as possible,
then a scan of the variety area close up.
Note : "RA" joined, bottom left stamp.
