The 1949-1951 Australian Coat-of-Arms series would have to be one of the finest designs from the King George VI era, and by far the most difficult to obtain in a complete set, The three very thin papers, being the 5/-, £1 and £2 values, being only 0.085mm thick.

The £1 and £2 very thin papers are very rare and are very seldom seen on the market, more-so if the stamps are well centred.
