The "Australian Miniature Money" series reproduced discontinued circulation coinage in fractional gold specifically because the original bronze cent had been demonetised in 1992, making literal pocket change a legal impossibility. At 0.5 g, these are among the smallest gold proofs the Royal Australian Mint has produced, requiring dedicated equipment and handling protocols distinct from standard proof production.
