It sets out the exact physical specifications—weight, size, metal purity, and design—for each coin so they qualify as official Australian currency.\n\n**What it does:**\n- Authorises seven different coins: four silver $2 coins, one silver $1 coin, and two gold coins ($100 and $50 denominations)\n- Specifies precise technical details for each coin:\n - **Weight and purity**: For example, the silver coins must be at least 99.9% pure silver, with exact weights like 62.770 grams (plus or minus 0.5 grams)\n - **Dimensions**: Exact diameter and thickness in millimetres\n - **Design**: Detailed descriptions of what's on the front (obverse) and back (reverse), including special \"privy marks\"—small commemorative inserts or coloured prints featuring historical coins, flags, or symbols\n\n**Who it affects:**\n- **Coin collectors and investors**: These are bullion and commemorative coins, primarily bought by collectors or as investments\n- **The Perth Mint**: The government-owned mint that produces these coins\n- **Anyone accepting these as payment**: Because these are legal tender, businesses and individuals must accept them at face value (though their metal content is worth far more)\n\n**Why it matters:**\nWithout this Determination, these specific coins couldn't legally be produced as Australian currency. The document ensures consistency and authenticity—every 2002 Kookaburra or Nugget coin matches these exact specifications. The \"privy marks\" (special inserts like a gold nugget coin, Spanish pillar dollar, or Liberty Bell) make these particular issues collectible rarities."},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
