Chau, Penny!

As long as they're destroying the currency ...guess who's first? Except that I think even dirt will become too valuable. One of the suspected reasons for the "small change" shortages that occur in Buenos Aires is the supposed "melt" value of the coins here. That's one theory behind the bi-metal Argentine Peso coin: combining the two metals makes the resultant melt less valuable than its component parts.

Why not plastic? Being petroleum-based, it would actually leave a certain "ring" to it.

I like the steel idea, though. It brings to mind a time when we actually fought the fascists...
