I'll check what I have if I'm able to this weekend (my graded coins aren't stored at my house). I think I have a CAC coin.
Might be an "old school" opinion, but my late mentor (
Karl Kohls) always preferred PCGS above the others, and would pay a small premium for PCGS graded coins compared to other services when buying things. That said, he also once told me that if he had a really good coin, he'd sometimes send it into PCGS a few times until he got the grade he thought it deserved. He called it "fishing for someone who didn't skip their lunch break."
