Oh yeah, no doubt that is the S33. Great coin and thanks for sharing. I have one in a slightly higher grade with some red. This is one of the most desirable from the 1899 year. The marks in the dents are extremely strong and are from die damage.
I noticed that on this particular year, for whatever reason, some of the RPDs do not always exhibit the same repunching. For instance, one of my 1899s matched a plate coin in Rick's book, but lacked repunching on the flag of the one. It took advanced study by members of the club, and a side-by-side comparison to the plate coin, to sort it out. The repunching on that coin appears to have been partially polished out.
I also have several examples of the S-1 and S-2, but I have an example of each that doesn't exhibit repunching on one of the 9s. Initially, they appear to be new - but die markers are present that confirm otherwise. This adds to the mystery of the 1899 IHCs - the die chips on the 8th feather may always be curious.
