The OGP rolls you have posted look ok, and most likely authentic.
If I was going to buy any of those, I like the sealed mint boxes.
I also agree that paying a premium for Sac's as a investment might
not turn out to be much profit. Most of the time I have seen collectors
do similar, will end up dumping them for face value.
This is a hobby, it is best to collector for fun.
That said, I do stack a lot of modern coins. I feel if your stacking quality
coins as close to face as possible, then you might not lose money.
