Might be dipped but probably circulation wear which is very evident on the first photo. As a coin circulates, it will quickly lose its mint frost and become an AU example. AU-58 coins still have some luster but an AU-53 would have virtually none left. Depending on how it was handled, the coin may have very few marks but still exhibit poor luster. Finger oils and contact with a pocket will do that quickly.
