Pubco's relations with the Banque centrale du Luxembourg have a dynastic element to them. Since 2004, Pubco has been publishing inclusions of the commemorative 2-euro coin bearing the effigy of Archduke Henri's family. These have included the ducal monogram, Berg Castle, Hereditary Grand Duke Guillaume, and his venerable ancestor, Grand Duke Adolphe of Nassau-Weilbourg.

Minted at the French Mint, the Mint of Finland, and the Royal Dutch Mint, the coins are offered in series of a maximum of 15,000 coins. Most sell out the same year they enter circulation. The high-quality laminated case, into which the coins are inserted by hand, bears on its face a painting of His Royal Highness and a French text describing the milestones of his reign. Its presentation each year at the World Money Fair is a major event in the numismatic world.

To date, several national currencies have entrusted their embedding work to Pubco, including the United States Mint, the Royal Canadian Mint, and the Magyar Pénzverő Zrt (Hungary's national currency).
