Recently I noticed that my 100 CHF cannot be exchanged since the Swiss National Bank assigned a rule. There was no way for me except sending by post. Does anybody have any experience. It is written in website that for Switzerland it is recommended not to send by post. However, the SNB itself accepts it this way.
What is the difference between Switzerland and other countries regarding sending cash? Please let me know if you had any experience?
Update: They received it no problem! This forum is conservative!
