 Though Aksumite coins are indigenous in design and creation, some outside influences encouraging the use of coins is undeniable. By the time coins were first minted in Aksum, there was widespread trade with Romans on the Red Sea; Kushana or Persian influence also cannot be ruled out. Roman, Himyarite, and Kushana coins have all been found in major Aksumite cities, however, only very small quantities have been attested and the circulation of foreign currency seems to have been limited. Though South Arabian kingdoms had also minted coins, they had already gone out of use by the time of certain Aksumite involvement in South Arabia under GDRT, and only very rarely produced electrum or gold denominations (silver mainly in Saba ' and Himyar, while bronze in Hadhramaut), making influence unlikely. The major impetus, however, was not emulation but economical; the Red Sea and its coasts had always been an international trade area and coins would greatly facilitate trade and wealth in the now "world power." Despite these influences, the coins were of genuinely indigenous design, and foreign influences were relatively weak and few in number.
