I don't think so... at least not at this time.
So many of the higher numbers only have 1 or 2 in 9.8 so I'm really concerned about grade drop on those and having to then find others...
But I do plan on getting the first 50 in CGC 9.8SS, the last 6, and several keys between 50 and 150 (60, 93, 100, 106 most of which I have I believe) and some random issues here and there!
Most of them are Larry of course but I also have signatures from Golden, Trimpe, McLeod, Zeck, Perez, Conner, Grant, and McFarlane. It's been fun finding everyone's signature!
