Several points: firstly i would assume every country has a process for disposing of bad and worn out notes and coins. If not i'm sure someone could work out how to profit from recycling dead pennies in true capitalist fashion. This leads on to my second point which is when the government has time they should get around to issuing a bill removing pennies (and maybe other smaller denominations) from legal tender.
But there is a wider point which i want to discuss. How long will physical cash last? I'm very fuzzy on this but i think in some of the Asian countries it is practically an endangered species. Tax people don't like large denomination notes. And virtually no legal big transactions take place in cash. America must profit massively from the fact that in many other countries dollars are the go to black market currency but that is a very singular advantage.
