Most of what you've posted is very generic material in the apparent best-case conditions; I sincerely hope that the labeled/claimed grades/prices played no part in your decision to buy or the price paid.
I'd never buy anything from ncgs they advertise on Craigslist and slab anything ms65. I've learned to only trust pcgs and ngc.
In my opinion, based on the first picture you took, only the 1884 Morgan would grade in the realm of mint state. The others look cleaned with AU details.
SGS is one of the worst tpgs out there , constantly overgrading AU coins as MS-66 or better . I'd get the ANA grading guide to help you to learn to grade on your own as it's one of the most important aspects .
