I don't think it's rust. It doesn't have any iron in it. It's probably just what's called toning. There's nothing wrong with toning so it's better not to try to clean it. As for sealing, if you like the coin you can try putting it in a two by two holder or a coin capsule, but I'm not sure if the coin's value warrants the expense.
