And anyone trying to sell it... is doing so illegally.

There is nothing illegal about selling classical music. Is selling a work of Shakespeare illegal? Nope. Just because the copyright expires does not mean it can't be sold. That just means that anyone can sell or give it away, or base works on it, without paying any royalties to the owner. You can't really claim the originals as your own work, but you can certainly sell them.
