Do you know where I can change coins for cash in Geneva?

I already tried in the UBS office in Rive and in Confederation Centre but the service is not available.

Thanks

Have you tried the main post office, close to Cornavin?

Try the Post Office, although they might charge you a very small fee.

If you do not have a LOT of coins, wouldn't it be better just to use them while doing you grocery shopping. Atleast I reduced my coin count this way. Just take same denomination coins and of a fixed amount and then give it at the counter after your shopping. If you do not mix denominations, it is easier for the cashier to count it as well as it is not very slow that the people behind you in line start groaning you
