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.
Your coin is either a copper Penny, a Halfpenny or a Farthing with George IV on the front and a seated Britannia on the reverse. The Farthing is 22 mm in diameter. The Halfpenny is 28 mm in diameter. The Penny is 34 mm in diameter.
All Farthings from this period are made from copper. The 1825 Farthing obverse has a left facing George IV with the Latin inscription "GEORGIUS IIII" and "DEI GRATIA". The reverse has a right facing seated Britannia holding a trident with her left hand and a shield with her right hand beneath her. The date is below Britannia and the Latin inscription "BRITANNIAR REX FID DEF" is around the circumference. See the link below for an image.
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.

"Georgivs Sextvs Rex" is Latin for "King George the Sixth". If the coin says only "Georgivs Sextvs Rex" on the obverse, it is likely not from Britain but rather one of its colonial holdings - the name of the colony would be on the coin somewhere. Any bank in this colony might then be interested in buying it, especially South Africa.
If the inscription in total reads GEORGIVS II REX on the obverse, with BRITANNIA on the reverse, your description lines up with a copper coin, but there were no copper coins minted in 1757 and all Pennies prior to 1797 were a small silver coin. You may have a privately minted coin or a medallion.
No, it is not a very rare coin (as it is believed that 1,698. 000 of them were out in 1952). You can sell this with about $9 if the coin is in good state and with about $16 if the coin has never circulated.
The words Georgivs II Rex on a coin (or similar) would translate as George the 2nd King, or King George the 2nd if you prefer.
