CS 24/7 ric flair the bloody terry funk figure (I think it is 1 of 100 but not sure) bobby heenan in a weasel suit toyfair sgt.slaughter CS ring giant warrior in his usa attire from royal rumble 1991 CS roddy piper in the boxing attire from Wrestlemania 2 I know there are more but i can't think of them.
Outside any of the online exclusives, or the 1/? figures, the most valuable ones to me seem to be..
AD 1 Jeff Hardy/Dreamer (For the Hardy) RAW X Hbk (First RA) CS1 Warrior and HBK CS8 Hulk Hogan Black and White Undertaker RA1 Brock Lesnar Ra 43 (I think ?) Kofi Kingston Kenzo/Dupree 2pack Spike Dudley w. Hardcore Title WM 2000 Flashback RAs of The Dudleys, Benoit, and Kurt Angle WM 14 Flashback 2-pack HBK Vs Steve Austin Double Slam 4 Hardyz ROTR1 Taz ROTR3 Raven BCA Superstars 3 re-release Diesel and Goldust Grudge Match sets - Owen/Bret, Diesel/Razer, Luna/Sable RA 9 Booker T/Steve Austin (Short packed - running line change) Classic two packs Series 1 (LOD, Rockers, Hart Fund)
To get these MOC you may find yourself paying a pretty penny!
oh and I forgot the Wrestlemania 20 winners set! The Christian in white and Guerrero are really hard to find MOC (So to speak)
Also due to limited retail release series like the Superstunners set, the last Classic singles and 2-pack Series, the Off the Ropes series and the Ringside Rivals series...not really because they stand out, but because they weren't released at Mass like other jakks sets.
