2 Dollars - Elizabeth II Caribbean Monk Seal

The Caribbean monk seal (Neomonachus tropicalis) was almost certainly already extinct by 1995. The last confirmed sighting occurred in 1952 near Serranilla Bank, and a 1973 survey found nothing. The IUCN didn't formally declare the species extinct until 2008, which means this coin was struck during the awkward interim period when the animal was functionally gone but not yet officially so. The Bahamas issued it as part of a broader conservation-themed series, though the subject it commemorated had likely vanished from the wild four decades prior.
