Australian and NZ currency.
 

Need advice what to do with leftover currency (A$260 and NZ $100) from my last trip. Since I won't be going back until 2017 is it better to sell it (if you can find a place to take them) or wait until 2017? Also no place will take a prepaid cash for any tour , credit cards only. Any ideas

There's no right or wrong answer - only different outcomes and which is "best" depends on your particular circumstances.

You already lost a few "dollars" when you bought the Foreign Currency and you'll lose a few more dollars when you convert it back to your home currency. And then you'll lose a few more dollars when you repurchase the foreign currency for your 2017 trip.

So, if you will definitely be going back to both countries and it doesn't cause you a financial burden to have the equivalent of about $250 just sitting in your top drawer you should just keep the $AUD's and $NZ's.

If you need the cash now or if there's a chance you may not return then go to one of the prominent banks where you live and exchange the money.

If it were me, I'd just keep the foreign currency.

OOPS! That should read "… the equivalent of about $250US …"

By the way, you didn't ask but here's a hint for future trips: When leaving a foreign country consider using the bulk of your unspent foreign currency to settle a portion of your hotel bill and charging the rest of the balance to your credit card. That way, you won't have to worry about converting the money back to your home currency. I routinely do this when I travel and keep only enough "foreign currency" to pay for the cab to the airport and tip the SkyCap a couple of "dollars" for helping me with my luggage. If I have a dollar or two left over it's no big deal.

Thank you for good advice. I will just hold on to them unless someone would contact me to take them off my hands (traveling there for example). D.
