A little tough to tell from the photos if it's been cleaned. Usually the surfaces, particularly in the fields, would appear "dull gray" rather than silver bright if it's been dipped too much. I don't see the parallel lines that are associated with a "scrubbed" coin.
However, given that this is below Mint State, somewhere in the mid-AU range, it doesn't make a ton of difference one way or another. This is a common date and it would only gain any significant collector value if it were at least MS 63 or 64.
