2023 Ningaloo Eclipse Medallion Cover This 2023 Ningaloo Eclipse Medallion Cover commemorates one of the most spectacular astronomical events of the 21st century. On 20 April 2023, the eyes of the world turned to the Exmouth Peninsula in Western Australia as a rare hybrid solar eclipse plunged the region into a brief, midday darkness. This cover serves as a permanent record of the "Ningaloo Eclipse," a phenomenon that will not occur over the Australian continent again for centuries. Product Overview This release captures the precise moment of totality, combining detailed scientific data with high-quality numismatic and philatelic design. The Medallion: Features a limited-edition medallion housed within the cover. The design depicts the celestial alignment of the Sun and Moon, celebrating the rarest form of eclipse—the hybrid (annular-total) solar eclipse. The Stamp: Includes a commemorative stamp from the Ningaloo Eclipse issue, postmarked to mark the date of this historic event. The Postmark: Features a First Day of Issue postmark dated 20 April 2023, the exact day the Moon's shadow crossed the Exmouth Peninsula. Limited Production: This release is strictly limited to a mintage of 2,500 units. Please note that individual serial numbers will differ from those shown in listing images. A Rare Celestial Event A hybrid eclipse occurs roughly once a decade, but the Ningaloo event was particularly significant; the last time a hybrid eclipse was visible over Australia was in 881 CE. During the 2023 event, the Moon’s shadow travelled at 2,700 kilometres per hour along a path just 41 kilometres wide. For 62 seconds, observers in Exmouth witnessed the "Bailey’s Beads" effect as sunlight peeked through lunar mountains, followed by the total exposure of the Sun’s corona. Technical Details Event Date: 20 April 2023 Totality Duration: 62 seconds (Exmouth) Mintage Limit: 2,500 Condition Note As this item is now three years old, please be aware that the cover may exhibit light wear consistent with careful handling and storage. This can include minor corner bumps or light surface marks on the pictorial envelope, which are common for authentic medallion covers of this age.
