World stamps encompass philatelic issues from all continents and countries, reflecting the postal, historical and cultural diversity of nations throughout the nineteenth, twentieth and twenty‑first centuries. This category includes used and unused stamps, thematic series, regular issues, commemorative stamps, service stamps, varieties, proofs, printing errors and items of special interest from different international postal administrations. It covers classic issues from European, American, African and Asian countries, as well as modern and contemporary series illustrating heritage, fauna, flora, historical events, notable figures and global themes. Foreign stamps offer collectors a broad and multifaceted field of study, allowing exploration of printing techniques, face values, postal rates, postal systems and historical contexts associated with official issues from each country. This category will be progressively expanded with the extensive international philatelic stock available.
