Australian Silver Proof Dollars

1998 Howard Florey

.9999 Fine Silver

The 1998 $1 Fine Silver Proof Coin captured the tenacity of Howard Florey and his research team in their efforts to make antibiotics available. Australian pathologist and co discoverer of penicillin. Born in Adelaide, Australia, and educated in medicine at the University of Adelaide, he later studied and taught in England. In 1935 he was appointed director of the Dunn School of Pathology, University of Oxford. Florey studied naturally occurring antibacterials, of which the Penicillium mold discovered by Sir Alexander Fleming seemed the most promising. In 1939 Florey and the German-British biochemist Ernst Boris Chain isolated the active agent, penicillin, from a fraction of the mold and formulated procedures for extraction and production. With British industries affected by World War II, Florey took his process to the United States, where private and government laboratories produced sufficient quantities to combat bacterial infection in wounded soldiers. For his work he was knighted in 1944, shared the Nobel Prize in physiology or medicine in 1945 with Chain and Fleming, was elected president of the Royal Society in 1960, and was created a life peer in 1965.

Intricately frosted against a mirror-finish background, the detailed portrait of Florey will create a stunning addition to any collection. On the obverse of the coin appears the new effigy of Her Majesty Queen Elizabeth II, by Ian Rank-Broadley.
