I am one that don't think you got a deal but I don't think you to much either, I think you paid what it is worth. This is a green label but its not a first gen PCGS slab so these don't have new collectors thinking they may be an upgrade in them like the first generation slabs do. The experienced collectors know that most that would upgrade has been done so now so it is very hard to get a old PCGS slabbed coin that will upgrade if sent in now. There are some out there but you have to be very good at grading yourself to find them because you will look at 2000 coins before you find 1 that may upgrade. Its very hard to find an upgrade by pictures also so chances of getting one on
ebay or other online sites is pretty hard. I have actually seen more that was very lucky to receive the grade it had in my opinion than ones that would be a lock for an upgrade
