UNESCO Commemorative Medals Since 1966, UNESCO’s Philatelic and Numismatic Programme has issued two series of commemorative medals: World Heritage The first series illustrates remarkable monuments and sites of humanity’s cultural and natural heritage that are threatened with destruction, and UNESCO's efforts at an international level to save them. Some, like the Nubia and Borobudur campaigns, are among UNESCO’s biggest success stories in the preservation and restoration of monuments. Also included are other heritage sites that UNESCO wishes to highlight. Anniversaries and Historic Events The second series relates to anniversaries of outstanding persons and historic events. UNESCO has been given the task by its General Conference of focusing public attention on these dates, on the basis of proposals put forward by Member States, with the aim of contributing to better international understanding. Some 55 medals have been issued so far. With the exeption of a few, the medals are struck in gold, silver and bronze, most of them by the Paris Mint, and sold in a presentation box with a stand, only at theUNESCO Giftshop.
