Description
The reverse of this prestigious coin faithfully depicts the legendary U.S. "Z-Grill" stamp, issued in 1868 as part of an experimental series featuring an embossed grill pattern designed to prevent reuse. The Z-Grill variant, recognizable by its horizontal impressions, is now one of the most prized treasures in global philately - only two examples have survived. The stamp is recreated with exceptional attention to detail, including the signature grill and original blue tone. The obverse features a golden postal horn on a stylized world map, framed by a border inspired by stamp perforations and adorned with vintage modes of transport such as a hot air balloon, steam train, horse rider, and early airplane. The design is completed by the Coat of Arms of Cameroon and the inscriptions: "REPUBLIQUE DU CAMEROUN" - the issuing country, "2025" - the year of issue, "Ag 999" - the silver purity, and "500 FRANCS CFA" - the face value.
