I do the ziploc bag thing too! (I thought I was the only one)
I have currency from: Hong Kong, UK, euro, Switzerland, Barbados, Bermuda, Chile, Argentina, Venezuela, Brazil, Macau, Gibraltar, India, Singapore, Canada, and probably others too!
I seldom spend much cash because, as noted, I don't earn miles for spending cash. But sometimes you need to have it in case a particular restuarant's machine is broken or you need to take a taxi.
The one issue I have encountered in keeping bills in ziploc bags is that when I eventually return to those places and try to use the stored bills, sometimes they are no longer in circulation, and I must go to a bank during business hours to exchange them for the latest version. A bit of a pain. But still, fun souveniers!
