Currency, customs, postal stamps, and exchange rates
Not all exchange in the horn of Africa involved currency, but when it did the two parties turned to the 1780 Maria Theresa thaler (abbreviated as MT thaler). The thaler bore the effigy of its namesake, the 18th century Habsburg empress Maria Theresa. The thaler was used as the de facto currency in many places around the world - including Ethiopia - where no official local currency existed.
For small change, rifle cartridges and salt bars were used. The salt bars were four centimeters square and about 20 centimeters in length, slightly tapered at the ends. They weighed about a pound and a half - around 750 grams. In the 1870s, the value of the thaler varied from eight to twelve salt bars, depending on the quality of the bars. The value of the bars declined with use, through wear and because traders shaved them down.
Besides their value as small change in transactions, salt bars could be sold directly, as pictured here. (Salt bars are stacked in the foreground.)
In the 1890s, shortly after becoming emperor of Ethiopia, Menelik ordered an Ethiopian thaler coin be struck with his image. Printed postage stamps with the emperor in profile were also ordered. Alfred Ilg, Menelik's advisor, had urged Menelik to promote these emblems as part of a symbolic defense of Ethiopian sovereignty. Ilg was right. Postage stamps may seem banal, but in an age when most state relations were bilateral (that is, state-to-state), postal delivery required an unusual degree of multilateral cooperation. A letter might pass through several national postal systems before reaching its destination, incurring costs without generating revenue; reciprocal acceptance of postage was a courtesy among nations - it amounted to de facto recognition of membership in the broader community of peoples. The issue mattered enough that Italy lobbied - successfully, for a time - to block Ethiopia's bid to join the Universal Postal Union.
As for the Menelik thaler, it never caught on. Various explanations surfaced - that Ethiopians mistrusted unfamiliar currency; that the coins showed Menelik in profile rather than full face as dictated by Ethiopian artistic convention. It was even suggested that Ethiopians were simply too fond of Maria Theresa's ample décolletage. Whatever the reason, the Maria Theresa was entrenched. Menelik postage stamps, however, were widely adopted. In fact, after Adwa, Italian prisoners posted letters home to their families with the new Menelik stamps.
Exchange values
The exchange value of the Maria Theresa thaler varied, just as the value of any service could vary according to time, circumstance, and the bargaining skills of the parties involved. Here are some quoted payments for various goods and services. Sources are given in brackets.
