Some advice on strange old English coins

Hi.. 
I googled coin collectors forum, and found this forum, so thought it would be a good place to get some advice.
I know nothing about coins so am hoping you guys could shed some light on something for me.
Recently i was clearing out a room and in a cupboard and i found an old box, This box contained a lot of old letters, millittay passes and 5 coins.
These coins are British half pennies from 1943 and 1944. In it's self i dont think they are anything special. But when i looked at them i noticed they are only stamped on one side. One side is stamped with the date, a picture of a ship and the words "half penny", The other side is completely blank and smooth
So i have two questions. Why are they only stamped on one side, and are they worth anything?

It doesn't look as though it has been ground down, The blank side is completely flat and smooth with no markings at all.
Im sure i have some double sided half pennies somewhere, I will compare the thickness.

If they are completely flat and smooth then they are definitely altered after they lef the mint. To create a true one sided coin is very rare an when they are are made the "unstruck" side will not be completely flat and smooth.
