Does it have any luster Dave? Usually when I see these in mint state they are rather dull like the 21-S, not quite as bad, but not blazing like other issues (although there are rare exceptions). At worst case, this is an AU coin.....it's really hard to tell with pictures.
Most of my grade opinion came from that left wheat stalk, it's extremely sharp. You can't usually go by the right one because non-parallel dies are commonplace with Lincolns.....it was also slightly out of focus in your pic. LOL
