King George IV died in 1830.
King George V was king in 1931.
British 1931 coins do not have any especially great (give up your job) value, but if in reasonably good condition, could get a few pounds.
Coins were not minted for South Africa in 1922....
Not enough information. George V was king from 1910 to 1936 and appeared on many coins of the 30 plus countries of the British Empire at that time. Do you refer to - British coins? A year set of coins? A full set of all George V coins? Circulated coins? Mint "uncirculated" or "Proof" coins? A particular denomination or type of coin?
A 1940 King George WHAT?
Try again. George VI died in 1952, which was the last year to feature his portrait on Canadian coins.
Yes. King George III became king in 1760 and ruled until his death in 1820. British coins were minted in most years of his reign and featured his likeness on the obverse of the coins.
There were no 1740 British Crown coins minted. The Crown coin was not regularly minted during the reign of King George II.
The silver in the coin is $17.29. In 1952 there were some special variants to the coin. There is the "SWL" variant, whose value ranges from $20 to $55. The "NWL" ranges from $17.29 to $27. The "WL" variant ranges from $17.29 to $24. In the future please add the condition of the coin so I can value it more precisely for you.P.S. King George VI was on coins from 1952, not King George V.
The initials HP on the coins of most George VI coins from most Commonwealth countries would be the initials of the designer of the King George VI bust, T. Humphrey Paget.
Please check your coin. The Royal Mint did not produce any Halfpenny coins from 1808 to 1824 inclusive. George III was king in 1809. George VI was not born until 1895 and did not become king until 1936.
King George V appeared on all British coins and the coins of most British Empire/Commonwealth countries from 1911 to 1936 inclusive.
There was King George V and King George VI. To get an estimate of value on an Australian predecimal banknote, you will need to provide the two signatories on the note and the serial number.
Coins were made in South Africa, England, Australia, India, West Africa, East Africa, Canada, and many other places inbetween. Let's just say that there were 20 different coins that featured King George V. These coins were made of Copper, silver, gold, and other metals, as well. Let's say the metal value varied from five cents to $1000. Then, there is the numismatic value. You expect anyone to know?!?
