As early as 650 B.C., man has fashioned metal into coins as a means of trade. The very first coins were struck in Lydia (present-day Turkey) from electrum, an alloy of gold and silver. The practice spread worldwide and continues to this day. While we may not use gold and silver alloys to produce our common, day-to- day-transaction coins anymore, gold; silver and even platinum coins are struck every year in mints all over the world. And you can purchase many of them through US Gold Firm.
