A striking example of a modern mint error, this 2020 Australian 50-cent piece exhibits a dramatic struck-through defect caused by oil, grease, or water contamination during the minting process.
The obverse and reverse show characteristic ghosting and incomplete strikes where the foreign material prevented proper metal flow and die contact. Sourced directly from original RAM (Royal Australian Mint) bags, this error coin represents an authentic production anomaly from the mint's 2020 coinage run. The 2x2 holder provides secure, archival-quality storage while allowing clear visibility of the error characteristics from both sides. A notable addition to any error coin collection, particularly for collectors focused on modern Australian mint errors and production varieties.
