Engraver: Ian Rank-Broadley

Ian Rank-Broadley FRBS is a British sculptor who has produced many acclaimed works, among which are several designs for British coinage.


Howard Florey in surgical garb - Developer of Penicillin (1898-1968)


Engraver: Vladimir Gottwald

Vladimir Gottwald was a member of the Royal Australian Mint's Design and Engraving Section. His portrait, designed following the British Royal Mint's invitation for a new effigy in 1996, was among the three designs submitted to Her Majesty for approval. Although Rank-Broadley's design was eventually chosen, Gottwald's design was approved for a once only use to commemorate the Royal Visit in 2000.

In 1998 the RAM released this NCLT Fine Silver (.999) coin celebrating the 100th anniversary of the birth of Lord Baron Howard Florey. The coin was released in a capsule in a square plush box. This silver version had, at the time, the new Ian Rank Broadly effigy of the Queen on the obverse side.  

The coin was also available, but with the previous Raphael David Makleouf obverse, in Aluminium-bronze as follows:-

As a MYO (Mint Your Own) coin with a "C" Mintmark in the visitor gallery of the Royal Australian Mint and came with a small coincard to house it.
From the Mobile Press at various Royal/ANDA Shows as follows:-
Sydney - "S" Mintmark in a Grey Coin Folder
Brisbane - "B" Mintmark in a Pink Coin Folder
Melbourne - "M" Mintmark in a Pale Yellow Folder
Adelaide - "A" Mintmark in a Purple Folder

Born in Adelaide, South Australia in 1898 Howard Florey is famously known as perhaps Australia's greatest ever scientist and having shared in the discovery of the anti biotic penicillin with Ernst Chain and Alexander Fleming. In fact he shared the Nobel Prize for Medicine with these gentlemen in 1945 for the discovery and extraction of penicillin.
