10 Dollars - Hailé Selassié I Reverse trial

Trial pieces for the aborted 1972 Ethiopian decimal coinage were produced in Addis Ababa ahead of a planned currency reform that never reached circulation — Haile Selassie was deposed by the Derg military junta in September 1974, ending both the imperial reign and any prospect of the new series entering use. Reverse trials in silver-plated bronze are production-stage tests, struck to evaluate die quality and relief without committing to precious metal blanks.

Fewer than a handful of confirmed examples are known to have left Ethiopia before the revolution scrambled imperial records and mint documentation.
