Gold, Foundation of Economies

Gold has been the basis of economies since the start of civilization, either by issuance as currency (for instance gold coins) or indirectly backing a paper representation of the currency through reserves, an addition it also is tendered as natural (nugget), processed ignot, or other convenient forms. As with Jewerly 24K gold is malleable for coin minting use so the gold is alloyed with other metals. Providing many opportunities, production has not grown in relation to the world's economies. In the last century world economies have become increasing complex and rely less on gold reserves being the principal variable affecting currency exchange rates.
