| Additional information |
The Perth Mint's high-purity .9999 ("four nines") gold standard, adopted for this series, required significant refining process adjustments when introduced — standard .999 bullion being easier to strike cleanly, with four-nines gold's softness demanding tighter die maintenance schedules to prevent premature wear on production tooling.
