The design of the coin is illustrative and may differ from the final result.

In 1855, a stamp was issued in Sweden that was intended to be blue-green.

By accident, it was produced in yellow – and it was this very mistake that made it priceless.

Today, only one copy is known to exist, preserved like a relic of the collectors’ world.

The coin inspired by this rare treasure reflects the paper’s texture, the printing hue, and the delicate wear of the original.

It is a story of how an error can transform into the most precious symbol of passion and chance — one that changes the course of history.
