            "description": " Coins were used by Europeans, but due to shortage even Europeans often resorted to payment in articles. \"European presence in the coastal regions of Sierra Leone led to an inland spread of stores that used cash as well as goods in exchanges, alongside an increase in Krio brokers who were responsible for bringing European manufactures to villages. Knives, kettles, chests and jars, as well as rum, tobacco, brandy, gunpowder and brass rods were brought to the interior in this way and generally exchanged for local produce. Other forms of monetary transaction were used in the payment of stipends to local chiefs, in the salaries of the military as well as payments for local services, such as repairs, for dashes (gratuities), at government stores and at the markets. [...] Because of their location the coastal towns of Sierra Leone acted as interfaces where international currencies could be found to circulate. After the abolition of the slave trade, Cuban and Brazilian traders struggled to obtain European manufactures for carrying out local exchange. To make their local payments along the west coast of Africa, they brought with them coins, silver dollars and then gold doubloons. Thus, from the turn of the century, to the ‘mosaic of currencies’, which included the Sierra Leone Company coinage and the iron bars system, could be added silver Spanish dollars, Mexican dollars, French five-franc pieces and Maria Theresa thalers as well as gold Spanish American doubloons (or ‘pieces of eight’), American five-dollar and French twenty-franc pieces. By the 1820s, however relatively small in amounts, the Spanish dollar had become the principal foreign currency across the coastal region.\" §REF§(Mew 2016: 199-201) Seshat URL: https://www.zotero.org/groups/1051264/seshat_databank/collections/GWWIKDDM/items/U3D2FQIH/collection.§REF§"

            "description": " “Finally, between the middle of the fifth and the middle of the sixth centuries, Lanka’s role in networks of connectivity seems to have shifted. The finds of Roman copper-alloy coins, probably arriving from India, and their imitation on the island, may suggest either growing monetization or growing interest in Western aspects of commercial or material culture (or both), and in the sixth century, at around the time that finds of Byzantine coins in South India cease, the Christian Topography gives a graphic but unique account of an island poised between two networks: the eastern and western Indian Ocean regions. The few finds of Byzantine and Sasanian coins documented from the island give some sup- port to this picture, although also serve as a reminder of how ephemeral these networks probably still were in comparison to local exchange within the island and with the nearby coast of India. It is difficult to assess what may have caused this change, and the tendency where it has been identified to attribute it to political changes in the Mediterranean world or to changes in Byzantine and Sasanian demand seems to derive more from the persistent narrative structures highlighted throughout this chapter than from the surviving historical evidence. §REF§ (Frasch 2017, 63) Frasch, Tilman. 2017. ‘A Palii cosmopolis?

            "description": " The following quote suggests that foreign coins were used in the market of Sinnar and the harbour of Suakin before the seventeenth century. “While Funj still knew no (official) coins or currencies in the early seventeenth century beyond the market of Sinnar and the harbour of Suakin, with the exception of gold in form of gold dust or braclets, (Spanish) silver coins (from American mines) increasingly entered the empire in the seventeenth century. This led to an accelerated export of gold and the establishment of silver coins in regional and even local markets in the eighteenth century, when silver replaced textiles and salt as currencies of exchange. This led to an even stronger import of small silver coins and the development of an imperial mint. In the late eighteenth century, the Spanish silver peso had become the major currency.” §REF§ (Loimeier 2013, 148) Loimeier, Roman. 2013. Muslim Societies in Africa: A Historical Anthropology.

            "description": " Maria Theresa dollar: “In Bornu, where cowries were introduced in the middle of the nineteenth century along with the Maria Theresa dollar, a different system of counting was in use. The unit of count was the rotl, an Arabic word meaning a pound weight; this unit is believed to have belonged to the copper coinage which was minted in Bornu in the late eighteenth and early nineteenth centuries. The cowrie rotl consisted of 32 cowries, or four gabaga of eight cowries each (the gabaga was the local traditional currency unit, a strip of cloth, which had replaced the copper coinage in the nineteenth century). According to various writers, the 32-cowrie rotl had a nominal value of 33, the odd cowrie being set aside to help in the counting, as a sort of tally, or as a discount for the trouble of counting. Three rotl would thus make an approximate hundred. This looks very like an attempt to bring a system inherited from currency units which could be physically divided into halves and quarters into relation with the cowrie systems in use on the lower Niger, where strings of 66 and 100 were known. The relation between the rotl and the Maria Theresa dollar was never fixed; in Barth's time it was subject to manipulation by powerful speculators, and ranged between 45 and 100 rotl to the dollar. Nachtigal put it at 120-130 to the dollar, and Monteil in the I890s at 135-160. The actual counting of cowries in Bornu was done in groups of four, not in fives as elsewhere in northern West Africa; it is probable that this method of counting goes back to the small copper coins of Bornu.” §REF§Johnson, M.

Meanwhile, despite these upheavals, the Mutapa state continued to thrive and became the hub in the interior for trade with the Indian Ocean in silk, ceramics, silver, and glassware, among other imports, in exchange for gold, ivory, skins and local cloth known as Machira, woven from local cotton.

Historically, cattle served as social capital in many non-centralized Voltaic societies, enabling marriages and funerary celebrations, and representing wealth. Consequently, the rejection of cattle, in addition to limiting the accumulation of wealth, may also indicate the beginning of matrimonial compensation in agricultural labor, typical of modern autonomous village societies.\"§REF§(Dueppen 2012: 30)§REF§"

The palace control of cowries and the elite domination of commercial development in the administrative and economic enclaves provided the final element in the emergence of the dual economy. The capital and commercial centres had developed highly sophisticated and well-organised monetary exchange systems. However, the vassal villages in the empire remained relatively static, with little circulation of either commercial consumer goods or currency forms (cowries or manillas).” §REF§Sargent, R. A.

            "description": " The literature suggests that culturally related and geographically adjacent polities in the Great Lakes region did not use coins as currency: barter was a common form of exchange, as was the use of tokens (e.g. ivory discs, cowrie shells) and articles (e.g. iron objects). In the case of Rwanda: \"Neighbors exchanged goods by barter. Hunters, farmers, and herders exchanged game, leather goods, honey, sorghum, beans, milk, and butter, among other things. Iron objects and hoes above all were preferably exchanged for goats and if possible cattle, but sometimes also for the goods we have just enumerated. Indeed, the hoe was probably already the standard of value as it was in the nineteenth century.\"§REF§(Vansina 2004: 30) Seshat URL: https://www.zotero.org/groups/1051264/seshat_databank/collections/GWWIKDDM/items/5J4MRHUB/collection.§REF§ In the case of Buganda: \"As we have noted, pre-colonial Buganda never developed a purely monetary economy, and even during the later nineteenth century barter was an important method of exchange, existing alongside a cowry currency. Nevertheless, the information we have on nineteenth-century prices suggests that virtually everything had at least a nominal cowry value. Moreover, other currencies existed alongside cowries, and some undoubtedly pre-dated the latter. Roscoe mentions a \"small ivory disc\" which he terms 'sanga', ssanga being the Luganda term for either a tusk or ivory in general. This, Roscoe claimed, was one of the earliest forms of money in Buganda; although clearly indigenous and probably much older than the cowry shell, it also had a cowry value. [...] A third pre-cowry currency has already been mentioned, namely the blue bead, and as we have also already noted, examples of beads have been excavated at Ntusi. From such archaeological evidence, it is possible to suggest that beads may be the oldest currency in the region.\"§REF§(Reid 2010: 122, 126-127) Seshat URL: https://www.zotero.org/groups/1051264/seshat_databank/collections/GWWIKDDM/items/2H64W34U/collection.§REF§"
