Tomás de Comyn, The Former Philippines Thru Foreign Eyes
“ The Chinese are accustomed to bring gold and silver as currency, mixed also with foreign coinage, to Manila for the purpose of buying the produce of the country; and all this the native merchants had recoined. At first only silver ounces were usually obtainable in Manila, gold ounces very rarely. This occasioned such a steady importation that the conditions were completely reversed. In the Insular Treasury the gold and silver dollar are always reckoned at the same value. ”
