I have gotten almost my entire collection CAC'd. I have gotten three gold stickers out of them. What I like is talking to John afterwards and learning from him. Its amazing what you see when he points it out that you did not notice at first. It gives you an appreciation of what true quality is. The other thing the CAC sticker says, is that John will buy the coin at fair market value at any time. I think that says a lot. The fact that you technically will always have a buyer for a coin with a CAC sticker.
