2001 Australian 10c Varieties

Posted on 07 September 2018

Following the introduction of Ian Rank-Broadley's new obverse of Queen Elizabeth II in 1999, the obverses on Australian coins underwent a number of small iterative changes, likely in an attempt to improve die life.

In 2001 the 10c piece was produced with two different obverse dies - on the first the designer's initials (IRB) under the Queen's neck are spaced and do not touch, while on the second more common design the leg of the R elides into the B, though the difference can be a little difficult to detect at times as the ellision is prone to filling.

Although the I R B (spaced) design is less common it is not rare and may be more common in mint sets.
