The near-fatal incident occurred in the mint's Canberra basement when a contractor was using a forklift to move the coin press.
The press became unbalanced and fell, narrowly missing a worker standing nearby.
Following an investigation by regulators into the May 3 incident, the Commonwealth Director of Public Prosecutions has filed three workplace health and safety charges.
The mint has been accused of two offences, which carry a maximum penalty of $1.5 million each, of failing to provide a safe working environment.
It also faces another offence with a maximum penalty of $500,000 for failing to provide the contractor with adequate safety instructions for transporting the coin press.
The matter is listed for mention in the ACT Magistrates Court on June 24.
