First One penny issue in Australia for Queen Elizabeth II.
On this issue the Perth mint mark was a dot after the word AUSTRALIA.
Specimens (proofs) were produced this year for official purposes only. According to CoinFactsWiki:
"Struck for Queen Elizabeth II's Coronation in 1953, a minuscule total of twelve, penny through florin, sets were officially produced at the Melbourne Mint, with the entire mintage ending up in the possession of the Chase Manhattan Bank in New York for their currency museum. Clearly, later deaccessioned or distributed, less than half of these have made their way to auction over the following six decades. The Halfpenny, missing from the standard Coronation set, was actually struck separately at the Perth mint (identified by the dot after Australia). While the true mintage remains unknown, its rarity likely even surpasses that of the sets."
