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.

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. One disc was apparently worth one hundred shells. Ivory played a dual role insofar as it was on the one hand a commodity valued for its own sake, and on the other a standard medium of exchange. The former role gradually took precedence over the latter, as demand for ivory from the coast increased, so that as the nineteenth century progressed, ivory as money all but disappeared. [...] 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.

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.

            "description": " The literature suggests that culturally related and geographically adjacent polities in the Great Lakes region did not use precious metals 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§"

That is, silver no longer flowed abroad so much in payments to bankers and soldiers but could be used at home; so vellón could be partly phased out, and from 1680 its face value was reduced by three-quarters. This stabilisation of the currency no doubt fostered the revival of the Spanish economy in the eighteenth century, contributing to a spread of the internal market. Silver coins themselves, of course, were notoriously vulnerable to hoarding and theft, and the growth of the economy also depended on some extension of credit facilities.”<ref>(Casey 2002: 70) Casey, James. 2002.

The negotiations took place on horseback outside the city walls. For the Huns, it was natural to do business without dismounting; the Romans, however, would have much preferred to have got off their horses and relaxed their aching limbs, but to save face they too remained on horseback. Attila's demands were not for territory but for money payments. Eventually it was agreed that the Romans would pay him the vast sum of 700 pounds of gold per year.”§REF§(Kennedy 2002: 38) Kennedy, Hugh. 2002. Mongols, Huns and Vikings: Nomads at War.

His body, draped in rare oriental silks, glittered with magnificent jewelry, costly gifts from Roman emperors hoping to buy off an enemy whom they had repeatedly failed to defeat. On his shoulder gleamed a great golden brooch set with a single slice of onyx the size of a man’s palm… That night, far beyond the frontiers of the Roman empire, Attila was buried. His body was encased in three coffins: the innermost covered in gold, a second in silver, and a third in iron. The gold and silver symbolized the plunder that Attila had seized, while the harsh gray iron recalled his victories in war. The tomb was filled with the weapons of enemies defeated in battle, precious jewels, and other treasures. The servants responsible for preparing the burial were killed so that they could not reveal its location.”§REF§(Kelly 2009: 6) Kelly, Christopher. 2009.

Production of gold and other minerals (excluding quarries) was much less relevant.” §REF§(Moreno-Brid and Ros 2009: 20) Moreno-Brid, Juan Carlos and Ros, Jaime. 2009.

By the 1860s these investments, by local entrepreneurs, led to the discovery of new, rich deposits of precious metals and thus helped to boost mining activity once again. The recovery of silver mining, in particular, helped to put an end to the liquidity crisis and the credit crunch that had so adversely affected Mexican businesses for many years since independence.”§REF§(Moreno-Brid and Ros 2009: 38) Moreno-Brid, Juan Carlos and Ros, Jaime. 2009.

During this time the export basket became more diversified, as shown by the decline in the share of minerals and metals in total exports and the corresponding rise of agricultural goods (see table 3.3). Moreover, though not shown in the table, the export of the minerals and metals now included, besides silver, metals such as copper, lead, and zinc, whose demand from the industrial centers of the world economy was expanding rapidly.”§REF§(Moreno-Brid and Ros 2009: 58) Moreno-Brid, Juan Carlos and Ros, Jaime. 2009.

While gold lodes and alluvial deposits of gold did not return especially large profits, the Bohemian lands became one of the greatest powers in the mining of silver... Since the profit from the mining of precious metals and minting of coins was one of the ruler’s rights, the coffers of the Luxemburgs were enriched, enabling them to finance their policies, both at home and abroad, as well as undertake new construction work and cultural enterprises. Although the value of the Czech groschen fell with the lower silver content throughout the 14th century (gradually half of what it originally was), this specie remained in demand in all neighbouring countries as late as the Hussite period. On the reverse of the Czech groschen a number of German towns impressed their mark as evidence of its high quality. However, the affluence of the Czech state was increased by the mining of other metals, and pewter, copper and lead – partly the by-products of silver mining – were exported to the German lands.”§REF§(Pánek and Oldřich 2009: 144-146) Pánek, Jaroslav and Oldřich, Tůma. 2009.
