In this case the original poster did not buy from NY Stamps but rather another person who did...
With the plate number attached, it is a 'no brainer' that it is a 528B (simply lookup the plate number here https://stampsmarter.org/features/P...ockHome.html
click on the 'Search by Plate Number tab). Aside from being badly centered, I think there are other issues with the stamp (like the stain).
I agree that someone with years of experience (perhaps decades if you are buying challenging stamps like the US W/F coils or Greek Hermes heads) can pick out which listings might be 'keepers'. For me, I try to not support this type of seller and would rather build a solid relationship with sellers who I feel are honest and are not doing harm to the hobby. NY Stamps is not 'a guy' but rather a large company with many people doing the listing of the stamps, I doubt most are collectors. Given the huge amount of material that goes through their company, it is little wonder that they do not spend time on their listings; the emphasis is to move thousands of listings per day. Quantity not quality (on any level).
The stamps shown, both with several issues, were worth a dollar or two, best used as space fillers until better examples come along.
