Several years ago I came across some threads on Net54 where Ted Z talked about a group of 6 Sovereign 460's that were much tougher than other Sovereign 460s to find.  I was very intrigued, and naturally I searched through my cards to see if I had any.  I was quite surprised to find out that I actually had one, the PSA 4 Evers.  This motivated me to see if I could collect the remaining 5 that I was missing.  I have started and stopped quite a few times because I was not sure if I'd be able to find and/or buy the Cobb or Chance due to their extremely low pop numbers.  Well, I was fortunate enough to be able to get those 2 over the past year.  Last night in Heritage I purchased the last card that I needed, the Mathewson Dark Cap.  I am grateful for all of the knowledge that Ted Z shared with this community.  One small example is that I would not have even known about these 6 cards if it wasn't for his posts on this topic.  I have copied 2 of those threads below for anyone who wishes to learn more about them.  Below are pictures of my 6 cards.  
Please post pics of any Super 6's that you own!
