This might not help you if you’re outside the country, but I believe the railway ticket office and the post office will also accept them. An anecdote: few months ago, my partner actually exchanged a 100 CHF note in the big SNB building on Bürkliplatz, and it’s essentially a Jason Bourne scene (although that wasn’t really Zurich in the movie). You walk in, a guy speaking with a stereotypical Bünzli accent takes your name, then brings you individually into an office where you can hand your gross old bank note to a man wearing a suit. Next to arguing about chess in German over a beer on the train, this is the most Swiss experience available. EDIT: Maybe more to the point, like everything else in Switzerland, apparently you can resolve this by sending a registered letter. In this case, if you mail them the banknotes at the Cashier’s office in Bern, along with your account information, they will wire you the money.
