In 1851, a stamp was released that was supposed to be blue — but was printed in the colour used for a different denomination. This printing error became one of the greatest philatelic sensations in Europe. Today, stamp from Baden, with its mistaken colour, ranks among the rarest and most valuable stamps in the world. 

The silver coin featuring its image combines historical significance and collector’s value, appealing to those who appreciate precisely captured details and unique stories.

Struck by the Mint Of Poland from 99.9% pure silver with Proof finish. The coin comes housed within a display case which includes the Certificate of Authenticity.
