Tysm for the feedback so far!
It's hard to see, & I will try to provide more photos; but the S looks to be of normal shape with a 2nd S imprinted to the right of it, rather than 'cut in' to the original S shape, they both have smooth/rounded edges that match.
I'm still a newbie at this but I'm definitely hopeful for DD! Going to send it in for grading to be sure :)
