There are literary pieces that refer to the first production of gold in rough, shapeless forms that were noted in the pre-Roman era of human civilization. It is believed these bars were produced in processes similar to todays cast gold. Ancient gold bars, although not referred to as bars at the time, were refined by melting the gold and pouring it into preformed molds. These molds, unlike those of today, were most likely made out of clay. Today, gold bars are available as minted ingots and cast gold bars, providing something for every investor.
