Looking at one of the new one pound coins I noticed something odd - what appeared to be a hologram at the bottom of one side under the Queen's head.
Apparently this is one of a number of anti counterfeiting measures.
It seems to be done by bending or cutting the tiny strips of metal at the bottom to produce the holograms.
In order to show the holograms more easily I found it was better to blur the final pics using Gaussian Blur.
They produce the 1 or the £ depending on the way the coin is viewed - quite a clever way to produce a hologram made of metal especially considering how small the little "grille" actually is.
All pictures were taken on my Canon 40D using extension tubes with the Canon 50mm f1.8 lens.
