Shawn ChambersI will agree with Frank and say that Series 6 & 8 are the most difficult series. I have heard many arguments for one over the other, but they are both hard to come by. Series 7 as pointed out, is very difficult, too, especially the Kelly (mascot) card, which I would love to see on the open market. It would be a real frenzy.
Even the more common series' can yield some tough finds as Zach pointed out. Besides the ones he mentioned, I know several people that would be on the hunt for a Series 5 Benny (myself included) and this is in one of the more "common" series. But, man, oh man, what a fun card! It is a fun set whether you collect by Series or city. Here is one of my Lexington boys...

Best of luck to you on your hunt.
