Analysis of information sources in references of the Wikipedia article "Guinea (coin)" in English language version.
The coins were named because much of the gold used to produce them came from the Gold or 'Guinea' Coast of West Africa and was provided by the Royal African Company, which had been granted a monopoly of the Africa trade from 1672 until 1698. Coins produced from African gold bore the company's distinctive emblem below the monarch's head: an elephant or elephant and a castellated howdah, an ornate canopied seat used for riding on elephants and camels.
