Introducing a third party that has eggs and will accept shoes he doesn't need because he knows somebody who will trade them for butter he does want is a step at the way. Keep moving down that road and sooner or later something is going to develop as a common medium of exchange. Gold, silver, copper and some other commodities in various places came to be that medium. Paper, until just some decades ago, was nothing more than a marker for these commodities. As an effect, coins made from those metals were created. Historians largely agree that the first coins were struck during the 7th century in Asia Minor, in an area that is now part of Turkey. 'Struck' is a proper term, since they were made by putting a blank metal piece between 2 die and striking the top with a hammer. Those die often had the likenesses of kings, since they were the ones who declared laws forbidding anyone else to produce currency. It was both a way to enforce their rule and guarantee the authenticity of the money. He that has the gold makes the rules. As culture and technology developed, metal coins came into greater use. During the 14th century coins came to be valued not just for their function in commerce, as works of art in by themselves. Petrarch is reported to experience a substantial collection of ancient coins. During the late 18th and 19th centuries coin production technology evolved to the point that hand minting was transcended by machine-made methods. Coin collecting at this stage took a new turn. Hand-made coins, irrespective of whether they're carefully alloyed and weighed, differ visibly. Even the most painstaking artisan can never produce 2 exactly alike. As an effect, what qualified as an 'error', making a coin more rare, had an entirely different meaning at the earlier era. Machines, though, can mass produce coins of consistent alloy and shape. Subtle, and also there is the situation where, not so subtle, faults can still happen, though. Double-striking, incorrect plates used, inaccurate dates and any quantity of human errors can cause machine made coins to differ from common. Because of their rarity, those 'bad' coins can have substantial value in coin collecting. Rarity, when all said and done, irrespective of whether the intrinsic value might otherwise be low, is a key element at the value of a collectible coin. By the mid-20th century - August 15, 1962 to be exact - saw the debut of the first international coin collecting convention at the U.S. Sponsored by the United States Numismatic Association, this event ushered at the truly contemporary era of coin collecting. Today, there are dozens of organizations across the globe and millions of collectors dedicated to the art and science of coin collecting. Shoulder-to-shoulder with their cousins in numismatics ( research of currency), they trade actively in stores and sites throughout the globe. Yet the urge is unquestionably similar 7 centuries after Petrarch: the pleasure of discovering and sharing the fervor of that rare treasure.
