The Museum of Stamps and Coins is marking the 70th anniversary of the wedding of Prince Rainier III and Grace Kelly with a new exhibition exploring how one of Monaco’s defining moments was immortalised through philately and numismatics.

Running from 13th July to 15th October 2026, the exhibition, Marriage of the Century in Philately and Numismatics, brings together an exceptional collection of commemorative medals, postage stamps, first-day covers, souvenir cards, philatelic documents and historic artefacts celebrating the royal wedding that captivated the world in 1956.

The marriage of Prince Rainier III to the Hollywood actress attracted unprecedented international attention, with millions following the ceremony around the globe. Widely regarded as a pivotal moment in the Principality’s modern history, the event significantly enhanced Monaco’s international profile and inspired a wealth of commemorative memorabilia that remains highly prized by collectors today.

Through its carefully curated displays, the exhibition illustrates how this landmark occasion was documented, celebrated and preserved for future generations, offering visitors a unique perspective on the role that stamps and coins play in recording history.

The exhibition also builds on the museum’s broader exploration of Monaco’s postal and monetary heritage, following the section dedicated to the Belle Époque of philately currently presented at the Prince’s Palace.

More than simply collectors’ items, the objects on display demonstrate how philately and numismatics serve as important vehicles for preserving cultural heritage and passing history from one generation to the next.

The exhibition is open from 13th July to 15th October 2026 at the Museum of Stamps and Coins in Monaco.
