The H.M. Treasury issued a One Pound note in the United Kingdom of Great Britain and Ireland from 1914 to 1927 featuring George V.
Any valuation would depend on the condition, serial number and the name of the Secretary to the Treasury.
Anywhere from $11 to $210. In the future, please add a description or condition of the coin so I can value it more precisely for you.
You need info such as this:
What condition?
What country?
Then we might be getting somewhere.
Such a coin does not exist. George III was born in 1738 and was king from 1760 to 1820.
You have a British coin ("Georgius IV D.G. Britannia Rex F.D." is abbreviated latin for "George the Fourth, King of Britain and Defender of the Faith") dated 1821. To get a value, the denomination and condition of the coin would need to be known.
This very much depends on condition, and what denomination the coin is. This can be checked on http://www.coins-of-the-uk.co.uk A coin of 1720 would say Georgius Rex or Georgivs Rex. George IV did not reign until the 19th century.
With minor variations, the inscription is much the same as appeared on all British Empire/Commonwealth coins of the period. It is heavily abbreviated Latin. GEORGIUS V.D G REX ET IND.IMP. GEORGIUS VI.D G REX ET IND.IMP. Expanded = GEORGIUS V DEI GRATIA REX ET INDIA IMPERATOR Translation = George V by the Grace of God, King and Emperor of India.
You have described every British coin issued in 1797. Please provide the type of metal it appears to be made from, the diameter of the coin, the inscriptions and the design on the reverse.
The phrase was used on British coins and is short for Georgius V Dei gratia Britanniarum omnium rex, fidei defensor, India imperator. It is Latin and in English it means: George V, by the grace of God, King of all Britains [sic], defender of the faith, Emperor of India.
In circulated condition, it's worth about $15
"GEORGIVS VI REX IMPERATOR" is Latin for "George the Sixth, King and Emperor". The coin is likely South African, but I would need to know the denomination and the condition to give an estimated value.
Your coin is either a British 1797 "Cartwheel" Twopence 41mm in diameter, or a British 1797 "Cartwheel" Penny 36mm in diameter. If somebody has drilled a hole in it, it might be worth a few Pence. Modified coins have no collector value.
Since the word "rex" is Latin for "king," it's only logical to note that the German word for "rex" is "könig" - the German word for "king."
GEORGIUS III DEI GRATIA REX (on the obverse) tells me who the King was in Latin, it does not tell me anything about the coin, although, you can sometimes make a guess. The full inscription usually reads "GEORGIUS III DEI GRATIA REX FIDEI DEFENSOR" meaning, "King George III, by the Grace of God, Defender of the Faith". Variations of this inscription, some more abbreviated than others, will appear on all George III coins. A similar inscription, suitably modified for the King or Queen's name and gender, appears on all British and Commonwealth coins. Queen Victoria's unabbreviated title would appear as "VICTORIA DEI GRATIA BRITTANIA REGINA FIDEI DEFENSOR INDIA IMPERATOR" meaning, "Victoria, by the Grace of God, Queen of the British Territories, Defender of the Faith, Empress of India".
The 1921 one cent coin from British colonial territories featuring George V has a nominal value of one cent. In circulated condition, it is typically worth its face value. However, if it is in uncirculated or pristine condition, it could have additional value to collectors.
