First people's Jewelers has been a precious metals exchange since 1974. Bullion is kept as an investment for many reasons. This includes gold, silver, and platinum coins and bars. You could use it to hedge against inflation, or as a way to keep accesible and easily liquified assets at home. In many jurisdictions, including Texas, do not collect sales tax on bullion sales. The price of bullion fluctuates with market demand, and is traded at a small premium above what is known as spot price. Spot price is the current market value of a commodity. In this case the commodity is a precious metal.
