The inner part of the coin shows a representation of the ‘Atomium’.

The engraver's initials ‘LL’ are depicted to the lower right hand side of the Atomium.

Two mintmarks appear along the edge of the inner part, one on the right and one on the left of the lower ball of the Atomium.

Twelve stars surround the design on the outer ring. The monogram ‘B’ appears at the top of the coin between two stars and the year of mintage ‘2006’ appears at the bottom of the circle between two stars.
