100 Shillings Emperor Penguin

Tanzania's wildlife-themed collector series from this period was produced under licensing arrangements common to small-nation numismatic programs, where a European mint — most likely Mayer & Wilhelm or a comparable German house — handled design, striking, and distribution with minimal involvement from the Bank of Tanzania beyond the issuing authority. The Emperor Penguin is, of course, entirely absent from Tanzanian territory or waters, which places this squarely in the category of commercially motivated legal-tender issues targeting the collector market rather than domestic circulation.
