            "description": " “Charles was also king of Scotland and of Ireland. The Scottish coinage dated from David I’s reign in the early 12th cent. But the number of coins struck was small, there were mints only at Edinburgh, Berwick, and Roxburgh, and what circulation there was came from England. The Scottish coinage had much in common with the English, partly through direct imitation, partly because each copied continental, and especially French, designs. But Scottish coins had their own peculiarities. Their international standing was undermined in the 15th and 16th cents. by persistent debasement. In 1423 the English government forbade the circulation of Scottish coins and at the union of the crowns in 1603 the Scottish pound was fixed at only one-twelfth that of the English. The falling value of the Scottish currency derived in part from the practice of mixing silver with alloy to produce the base metal billon. One result was that Scotland had less trouble about small change than England. James I introduced a billon penny and halfpenny: James III followed with a billon plack (from French plaque) valued at first at threepence and later at sixpence, a half-plack, and a copper farthing (1466); in James V’s reign the bawbee (1½d.) and half-bawbee were issued, and in Mary’s the hardhead was issued to help ‘the common people’ buy bread, drink, flesh, and fish. The billon coinage was discontinued after 1603, but twopence pieces in copper called hardheads, bodles, or turners continued to be issued until the Act of Union.”§REF§(Cannon and Crowcroft 2015: 1017) Cannon, John and Crowcroft, Robert. 2015.

            "comment": "The following quote clearly shows that foreign (non-Portuguese coinage) was in use in Portuguese colonies up until the middle of the 18th century; after that, though Portugal lost many of its East African colonies to Oman, it retained a sufficient presence in the Indian Ocean to suggest that non-Portuguese coinage such as the MT thaler would have circulated through the Estado da India as well, hence the \"inferred present\" code. \"The coins in use in the Swahili world since the sixteenth century reflect connections to ocean trade routes as well as the shifting influence of European powers in coastal political and commercial life. The commercial contacts of the Swahili merchants with both European and Islamic trade networks favoured the circulation of various types of international trade coins, among which the most important were the Spanish (pieces of eight) and Mexican silver piasters, and, from the eighteenth century, the Maria Theresa (MT) thalers or dollars (Figure 40.3). These coins were regular-issue coins that had legal tender status in their country of origin, but acquired a circulation far beyond their national borders and were accepted depending on recognition, familiarity and trust (Flynn et al. 1999: 155). \"The Spanish dollar was first struck in 1497 and then extensively minted in Mexico starting from 1535. It circulated widely in the world and became the most popular trade coin in Asia, especially in China (Flynn et al. 1999: 155). We have evidence of the use of these coins in eastern Africa since the seventeenth century. When visiting Mombasa in 1666/7, Captain William Alley reported the use of silver pieces of eight in the town (Freeman-Grenville 1959: 258). Piasters circulated between the Mascarenes, Madagascar, Mozambique and the East African coast in large quantities (Machado 2014: 235). By the mid-seventeenth century there was a reduction in the fineness of the Spanish dollars that led to its demonetisation in the British colonies. In the second half of the eighteenth century the fineness was further reduced, and this favoured the acceptance of the MT thaler (Stride 1956).\"  <a class=\"fw-bold\" href=\"https://www.zotero.org/groups/1051264/seshat_databank/items/C62TFXBJ\">[Pallaver_Wynne-Jones_LaViolette 2017]</a>",

The Pratiharas had struck a large number of coins which, with the beginning of their decline, gradually began to come into the possession of their powerful feudatories. Naturally, a large number of Pratihara coins were in circulation in the Candella kingdom during the reigns of Dhanga and Vidyadhara. Moreover, as Smith pointed out, 'they probably utilised chiefly the various sorts of Indo-Sassanian drammas in base silver, such as are mentioned in the Siyadoni inscription.' So Dhanga and Vidhyadara did not need to issue their own coins.[...] It was during the reign of Vidyadharma's successor Vijayapala (c. 1030-1050) and the latter's successor Devavarman (c. 1050-c. 1060) that the Candellas were decisively beaten by the Kalacuris and virtually lost their independence, until it was won back by Kirtivarman (c. 1060-c. 1100). Kirtiman probably [...] issued coins in his own name to proclaim himself as the independent Candella, and the proud victor of the mighty Laksmikarna.\"  <a class=\"fw-bold\" href=\"https://www.zotero.org/groups/1051264/seshat_databank/items/ATJMGIDM\">[Bose 1956, pp. 184-185]</a>",

[...] Many of these coins have been found in Kilwa and Mafia, and a small number in Zanzibar and Pemba, some in Oman and one at Great Zimbabwe (Brown 1991). The circulation of Kilwa copper coins was limited and they seem not to have filtered into Indian Ocean markets in significant quantities (Wynne-Jones and Fleisher 2012; Perkins et al. 2014). This suggests a local use and is a clear indication of the connection between these coins and the authority of specific rulers, rather than to a universal standard of value (Wynne-Jones and Fleisher 2016).\"  <a class=\"fw-bold\" href=\"https://www.zotero.org/groups/1051264/seshat_databank/items/C62TFXBJ\">[Pallaver_Wynne-Jones_LaViolette 2017]</a>",
