When we get international currency, usually by mistake, I just put it aside so I don't accidentally give it to someone in their change. I also like to collect them, along with old US currency if I come across it. I can switch it out for money in my own wallet. I've got quite a nice collection going after cashiering for many years.
What ticks me off though is last Friday I came across a new Alaska quarter, a new Hawaii quarter
and a wheat penny from 1929. I put them aside until I could grab my wallet and switch them out for two other quarters and a newer penny, but I completely forgot! The quarters I'll come across again, but pennies from before 1940 are very rare now days, and I'm kicking myself for not grabbing that penny.
