John, Let me know if you want me to just lurk. Deep down I know what you are doing will be good for all of us. Replying as you do to all the questions is confirmation of the great customer relations CAC has already being carried over to CACG.
The reason I'm writing to you:
In the "C" discussion you posted that you don't know if a problem free XF-45 exists and asked for an example. I think you should clarify that reply. Problem free coins exist all the way down the grading range. I've seen your stickers on them.
