Just some interesting points to this thread.

The majority of machines will actually accept silver coins without any problems and unless you get a "lucky" year their value is as on the face. Silver is also not being withdrawn from circulation. However...

Take a look at your 5 franc coins. Normally there is a few stars and Dominus Providebit sticking out an the edge. The SNB decided in the 80's to change this to be inwards ie the letters and stars are engraved in the side. These coins are no longer valid legal tender - not that most people will notice and until the end of this year can be exchanged at face value at banks. If you have one they are becoming scarcer and the value is increasing. So hold onto these.

Ending in 1939 the Swiss produced nickel coins for the 5rp, 10rp and 20rp which are almost always thrown out of machines as they are magnetic. These are also not legal tender. but are rather collectable.

The 2Franc coin has not changed in design since 1879. If you are very lucky you might find an 1896 or 1901 in which case keep if very carefully and drop me a mail.

For the 5Fr hope you get a 1952 as that will return something like 30 Francs more if in good condition. In 1991 and 1993 the 5Fr was not produced apart from in coin sets and the rarity value then puts these in the 100 Franc region...

As to the zumbo list you need to read what it refers to. This is the prices dealers charged for the coins in the condition stated which actually means you will get around 25% of this if you try and sell it. As the rarity increases so do the percentages so you can actually get 100% and more if you happen to get the right coin which is about as likely as winning the lottery.

Any questions about Swiss coins post 1850 I will gladly answer including given you realistic valuations and making/getting you an offer if you want to sell a collection!
