D G REG is heavily abbreviated Latin and it will appear on most British and Commonwealth coins when there is a Queen on the throne.
D G is often shown as DEI GRATIA meaning "by the grace of god".
REG is often shown as REGINA meaning "Queen". REX for a King.
Current coins featuring Queen Elizabeth II will have the legend "Elizabeth II D G REG F D" or something similar meaning, "Elizabeth II, by the grace of god, Queen and defender of the faith".
The full unabbreviated inscription reads "ELIZABETH II DEI GRATIA REGINA FIDEI DEFENSOR".
The legend in the latter part of the reign of Queen Victoria was a little more impressive and read - "VICTORIA DEI GRA BRITT REGINA FID DEF IND IMP". The literal definition is - "Victoria by the Grace of God, Queen of the British territories, Defender of the Faith, Empress of India".
Prince Charles, the Prince of Wales, has only appeared on two British coins to date. 1. The 1981 25 Pence (Crown) coin commemorating his marriage to Lady Diana Spencer. 2.
