Looks legit. The only thing that really sticks out me is the really flat detail on the ear. Almost looks like this area was filed away. Could be just the planchet.
Assuming this is not a details coin (some visible hairlines) and there is luster as you say (very clear in your images that luster is abundant), this is probably a low MS coin. Definitely not too shabby for $20.
