We have a bag of change from various countries. Europe, South America, Asia, etc. It has no value to us and I plan to get rid of it...hopefully at some airport donation bin. Issue is that I have no intentions of taking it along on a trip in the hope of finding such a bin. So, until we actually see one at our local airport that bag of change will remain at home and continue to grow! From time to time we have found a bin on the way home and dumped our change and small bills but this is not the case all the time. Hence the bag of coins.
