Since silver tones dark under a variety of environmental and chemical conditions, it isn't unusual to have variation in color among coins minted in the same year. To @hon's point above, you should absolutely not be cleaning any coins. Almost without exception it will reduce the value of these sorts of coins.
With that said, if the coin you are comparing against this one is here: https://goccf.com/t/486996, one big difference is in the metal composition, with that one being primarily copper rather than the silver of this one. If you look in the numista links that have been provided on many of your posts, you will find this sort of information.
