Methinks you need to learn a new word related to "cleaned;" that being: BUFFED. It would appear to me that the coin has been polished in some manner, which has the same effect and the same morality of the word "cleaned."
If some of us who think this coin is suspect are correct, either "cleaned" or "buffed" should have been included in the seller's description, or that individual/company is either (a) stupid, or (II) slimy.
If you live in civilization, you should be able to take this coin to a reputable dealer or experienced collector who can tell you in an eye-blink (at no expense) which side this coin (and its description) will land on.
If you aren't a member of a local coin club (assuming you live in a non-rural area), get involved with experienced collectors for your own well-being. There are a lot of people out there who are heart-willing to help and give good counsel, for no other reason than the pitty-pat of love of the hobby, hate of charlatans, and some cameradery (and maybe some volunteer labor, such as working the annual coin show or being president of the club). You'll save yourself a lot of $$ and embarrassment over the long run, and learn faster than you ever will on your own. All true collectors wish one another only good will and any education they can provide from their own experience.
