CAC is a secondary grading company. They confirm a given grade and place a green tag on the holder if they feel it is in the top 10% of a given grade. Sometimes when they feel it is under graded the place a Gold or bronze tag.
On higher value coins most grading companies are conservative compared to a more common year and mint mark of the same given coin type. If you look at the "2" MS-62 coins I currently have 10 1880 P Morgans in MS-63 grade that are equal too or not as nice as the one I posted. But this one is a Vam-6 Big dollar coin in MS so the grading curve is different. Not that that's right it is just the way it is.
