Straight off the top of my head, I think the term is "Ghosting".

Ghosting
When the outline of the design on one side of the coin appears faintly, in reverse, on the other side. It occurs most commonly on coins which are relatively thin compared to their diameter, and have relatively high relief. British pennies of Edward VII and George V are particularly susceptible to ghosting. Not to be confused with a die clash or brockage, which can create superficially similar effects.

I believe the image below is a dieclash. The arrows indicate where. Cheers.

Ghosting occurs because of the metal flow required to fill the image on one side of the die. It's more likely to occur on thinner planchets with higher relief designs. Die clash is caused by the obverse and reverse dies striking each other without a coin blank in between. The half penny below shows some good die clash, look between the O in ONE and the H in Half, the E in ONE and the F in HALF. You can quite clearly see the back of the kings head and the profile of his nose.

So, does ghosting add any other value to a coin rather than its regular catalog value?.. something good, or bad, this ghosting is?

Doesn't add to the value, in some cases I guess it could decrease the value of a coin in top grade.

Thanks Peter, amazing what good light and a nice camera can do.

The 1922 halfpenny also looks to have a diecrack from the rim, through the last A in AUSTRALIA and through the inner circle. Cheers.
