You refer to only part of the inscription on British and Commonwealth coins. OMN REX is abbreviated Latin for "King of all", OMN REGINA is "Queen of all". OMN REX (or OMN REGINA) has appeared on all British Coins from 1902 until the mid-1950's. Depending on the state of the British Commonwealth and the reigning King or Queen, the entire inscription might look something like this - EDWARDVS VII DEI GRA BRITT OMN REX FID DEF IND IMP which means "Edward VII by the Grace of God, King of all the British Territories, Defender of the Faith, Emperor of India". On smaller coins such as the Threepence, the Latin is more heavily abbreviated to fit it onto the coin. EDWARDVS VII D G BRITT OMN REX F D IND IMP
It means .50 in U.S. coin
The value depends on the coin's denomination and condition. Your question is incomplete.
It is an Australian coin. George VI of England was also King of the Commonwealth countries.
15 years is a very big mistake especially for a gold coin. I suggest that the coin is not what it appears to be. A reputable coin dealer will be able to identify your coin and give a valuation if it turns out to be genuine.
Check that one again. King George V died in 1936, so he wasn't on any circulating coinage dated 1957.
everyone or all
It is fairly easy. Apart from the dimensions, they are nothing alike. The British coin has GEORGIVS VI D : G : BR : OMN : REX on the front. The New Zealand coin has GEORGE VI KING EMPEROR on the front. British coins do not have the country name on them. The New Zealand coin has NEW ZEALAND on the reverse.
I have one. You tell me.
The life of someone who earned it
All you've done is told us that you have a coin from somewhere in the British empire dated 1950. We need to know the denomination, the country of origin and the condition for us to tell you the value.
I just acquired a coin from my spare change. It is in excellent condition ++ The Face side reads; George VI D : G : BR : OMN : REX The Reverse side reads; FID DEF One Schilling 1949 What is the value of this coin?
IND IMP was part of a much larger title used by British Monarchs. It is abbreviated Latin and means Emperor (or Empress) of India. IND IMP (India Imperator) was used on British and British Empire/Commonwealth coins from about 1893 when India became part of the British Empire, until 1948 when India became independent. Depending on who was king or queen at the time and which particular coin it appeared on, the legend may have appeared as - "VICTORIA DEI GRA BRITT REGINA FID DEF IND IMP" "EDWARDVS VII DEI GRA BRITT OMN REX FID DEF IND IMP" "GEORGVS V DEI GRA BRITT OMN REX FID DEF IND IMP" "GEORGVS VI DEI GRA BRITT OMN REX FID DEF IND IMP"
