Notes:
The 1946 Sixpence was the first struck in quaternary silver, a yellowish-white alloy of 50% silver, 40% copper, 5% nickel and 5% zinc. Before striking, the surface of the coin blanks are blanched with acid to remove the base metals, leaving a fine silver coating on the newly minted coins. However, the underlying alloy is quickly exposed through circulation. Quaternary silver was used in the Australian pre-decimal coinage dated 1946 onwards. At the same time, sterling silver coins, but essentially florins, were systematically withdrawn in order to repay debt. According to the research of author Tom Hanley, "... silver worth $6 million from remelted pre-1947 coins (sic should be 1946), was sent to the United States in 1956 to repay silver lent during World War II, when Australian coins worth more than $12 million were minted in San Francisco and at Denver."
