2007 20 Cent Varieties
Since the advent of the Ian Rank-Broadley obverse in 1999, the obverse used on Australia's decimal coins has changed subtly but frequently. Usually the changes have occurred as the years have changed, though in a few cases the changes have occurred during the production of a year's coinage. In 2007 for example, the obverse design was changed part-way through the production of 20c pieces.
|Round 2/thick 7||Blunt 2/thin 7|
On the first design for the year the date has a rounded tip on the 2 and a thick vertical stroke on the 7 while on the second design for the year the date has a flat tip on the 2 and a thin vertical stroke on the 7. Both varieties are common in circulation though the second variety is slightly more plentiful.
The Surf Lifesaver coins in mint sets all appear to be round 2/thick 7 coins though the existence of blunt 2/thin 7 Surf Lifesaver 20c pieces cannot be discounted.
