This is a common problem with hard currencies. It's usually solved by using multiple metals in the currencies; the US used gold, silver and copper. This causes problems when the metals are arbitraged against each other though. This might be alleviated by using a paper carrier with encapsulated gold foil added for small bills. Another solution might be a simple paper currency, backed by the metal - but again, this requires trust in the government that they won't print more than they hold.
