I recently received a €10 coin from the Netherlands whose reverse depicts Princess Catharina-Amalia of the Netherlands and her parents. The parents and baby cannot be seen at the same time. The appear when then coin is viewed from different angles, using a technique similar to lenticular printing.
The images don't look as great as the attached photo but they are really there. I think I have a silver plated base metal coin, which isn't mentioned on the Wikipedia page for Netherlands commemoratives.
I think this is the first coin featuring the technique. It was struck in 2003. A page on the Royal Dutch Mint's website goes into great detail on the marketing campaign for this coin but neglects to mention or explain the technique. The artists are Erwin Driessens and Maria Verstappen.
If anyone know the name of the multiple-image technique when applied to coin production please leave it as a comment!
