1 Dollar Coelogyne Rochussenii

Part of Singapore's long-running Orchid series, which the mint has used since the 1990s to position the island's national flower as a recurring numismatic theme — a commercially reliable format that has generated dozens of issues across silver and gold. Coelogyne rochussenii is a lowland epiphytic orchid native to Southeast Asia, including the Singapore region, though habitat loss has made it increasingly uncommon in the wild.
