So compiling Krause and Wikipedia this should be it:
- Mahaleki (1887-1894)
- Abyssinian Birr (1894-1931); 1 Birr = 20 Gersh = 40 Bessa; Werk ~ 4 Birr
- First Birr (1931-1936); decimalized: 1 Birr / Dollar = 100 Santeems / Cents / Matonas / Metonnyas
- Foreign currency (1936-1944)
- Second Birr (1944-date); 1 Birr / Dollar = 100 Santeems / Cents / Matonas / Metonnyas
Rulers:
- Emperor Menelik II (1889-1913)
- Lij Yasu (1913-1916) - No known coinage
- Empress Zauditu (1916-1930)
- Emperor Haile Selassie I (1st rule, 1930-1936)
Victor Emmanuel III of Italy (1936-1941)
- Emperor Haile Selassie I (2nd rule, 1941-1974)
- People's Republic (1974-1991)
- Federal Republic of Ethiopia (1991-present)
*Krause and Wikipedia list:
1 Birr = 20 Gersh (until 1903)
1 Birr = 16 Gersh (after 1903)
However, the actual silver content of the Gersh and Birr didn't change at the 1903 issue. So either:
- there is a mistake in the silver weights listed by Krause
or
- the 1903 change didn't happen.
**All dates I've listed in AD.
EE (Ethiopian Era) = AD - 8 years
