Abstract. Gold is considered a store of value and has been a sought-after metal since the dawn of human civilization. It was known to Egyptians as early as 3100 BC. The value of gold was reported to be two-and-one-half times the value of silver in the code of Menes, the founder of the first Egyptian dynasty. A gold mine in Nubia in Nile valley
