Saint Helena’s five-pence coin depicts Jonathan, the giant tortoise living in the grounds of the governor’s residence. The island’s historical guide estimates that he arrived in 1882 at about 50 years old, implying a birth around 1832, but explicitly says the precise day, month and year are unknown. Celebrations of his estimated 190th birthday in 2022 did not establish an actual birth date. This is a look at an existing island symbol and the evidence behind his age, not an announcement of a new commemorative coin.
