The "H" is the mintmark indicating that the coin was minted at the Heaton Mint in Birmingham.
All 1912 and 1915 Australian Pennies were minted at the Heaton Mint.
Also, the "H" will appear under the lower scroll and above the date rather than after the date.
Some 1912, 1918 and 1919 British Pennies were also minted at the Heaton Mint. These have the "H" to the left of the date.
Knowing the date and country of origin would help. If it is a British Penny, the "H" indicates that it was minted at Heaton in Birmingham.
An Australian 1912 bronze Penny (George V)(minted at Heaton - mintmark = H), uncirculated and in absolute mint condition could fetch up to $875 AUD. If it has been circulated but still in good condition, it might fetch anything from $1.50 to $160 AUD. There were 3.6 million minted. An Australian 1912 bronze Penny (George V)(Proof)(minted at Heaton - mintmark = H), uncirculated and in absolute mint condition could fetch up to $60,000 AUD. A reputable coin dealer will be able to give a more accurate valuation.
Apart from "AUSTRALIA" and "HALF PENNY", the only letters on the reverse (back) of a 1942 Australian Halfpenny are "KG". They are the initials of the designer of the reverse, George Kruger Gray. The letters "HP" on the obverse (front) (below the back of the King's neck), of all Australian coins from 1938 to 1952 inclusive, are the initials of the designer of the obverse (front), T Humphrey Paget.
If there is a mintmark at all, it will be a very small "H" to the left of the date in the exergue. The "H" indicates it was minted at Heaton in Birmingham. All 1912 Pennies without a mintmark were minted at the Royal Mint.

Where the date is, the mint letters are on left in corner (where the curve of the edge meets the line above date section) - though most coins do not have the marks. There is also H letter sometimes. Both are in Birmingham, England. H = Heaton, KN = King's Norton.
