Found money

DW thinks I have a "gift" for spotting lost coins - whenever we're walking along the footpath and there's a coin lying on the ground, invariably I'm the one that spots the coin. Today I was throwing out some trash at the food court and spotted 25c change someone had left with their rubbish on the takeaway food tray. Another contribution to DS1's money box ;) It got me wondering just how much loose change is discarded by mistake and ends up in the land fill every day.
