That article explains it all. The reason people are keeping coins is diminishing value. I keep coins in the car because I don't like the sound when I pocket them, walking around everyone looking at you wondering if you stole some catholic alter boy's bells.
Remember those copper 10cts of back in the days? Clever chutas realised they were worth more than their value and melted them. Talk of buying low and selling high
BBI will solve it :)
