In 1965, a new obverse was sculpted by Arnold Machin, showing a more mature Queen wearing a tiara. The legend on the obverse was also modified, by shortening the phrase "Dei Gratia" to "D.G." to save space. In 1968, the 10¢ and higher denominations were debased, their silver alloy being replaced by nickel. The dime of 1969 has two varieties, a large 9 (rare) and small 9 (common). In 1973, an RCMP quarter came out; it also has two varieties: a large bust (rare) and small bust (common).
