Trade Coin
Trade coins are coins minted by a government, but not necessarily current within the territory of the issuing country. These quasi bullion coins (in rarer cases small change) were thus actually export goods - that is, bullion in the form of coins, used to bulk buy important goods from other countries, where they could be bought at a favourable price, compared to the purchasing power of the same amount of bullion within the trade coins' country of origin.
