I don't speak authoritatively by any means, but I believe it is the same for circulated coins as it is for MS coins: To merit a gold bean, the coin must be under-graded by the TPG by at least one grade. For example, if the coin has a TPG grade of VF-25, CAC deems it should have been graded VF-30, so it merits a Gold bean. Of course, if CAC thought that VF-25 coin should have been graded VF-35, it would still get a gold bean and the observer would have no idea that CAC thought it was under-graded by two grades. Probably happens only very rarely. Another unknown with regard to the Gold bean is this: With our hypothetical VF-25-graded coin that gets a Gold bean, what does that tell us about how CAC would consider that coin at the next higher grade. In other words, would that VF-25 coin be considered an A, B, or C grade coin at the next higher grade of VF-30? I don't know and I'm not certain anyone knows except maybe the magi in the inner sanctum of the CAC temple. But I don't think CAC tells us or even implies that a Gold bean would guarantee a Green bean at the next higher grade. I suspect they believe that no general policy should exist for this question because each coin must be evaluated on its own merits.
