Pre-Decimal Proof Coins
Pre-decimal proof coins represent the pinnacle of Australian minting craftsmanship from the era before Australia adopted decimal currency in 1966. These exceptional specimens were struck using specialized techniques that produced coins with extraordinary detail, mirror-like fields, and immaculate finishes. Unlike regular circulation coins, proof coins undergo a meticulous production process, including hand-polished dies and multiple strikes, resulting in coins of superior quality and visual appeal.
Pre-decimal proof coins can be divided into two distinct periods:
-
Pre-1955 Era: These proofs were struck on an ad-hoc basis, with inconsistent production numbers ranging from none to several dozen in any given year. Coins from this period are exceedingly rare and highly valuable to collectors.
-
1955-1963 Era: During this period, the branch mints in Melbourne and Perth struck proof coins specifically for the collector market. Mintages ranged from approximately 300 to slightly more than 5,000, making these coins more accessible while still maintaining their collectible status.
