Interpretive writing - Isaac's great idea! Have a look at some of the change in yourpocket and you’ll see that most coins have ribbed edges as if they're scarred.Such textured surfaces can be observed in almost every coin of the worldno matter where it came from. But such coins first appeared severalcenturies ago. So why are so many coins ribbed? Here's the rest of the story. The story goes that once upon a timecoins were evaluated by the amount of precious metal contained in each likethese ancient Greek silver coins.These are made of electrum which is a naturally occurring alloyof gold and silver. Not only are they of irregular shape, the edges are smoothwith no marks or scratches on them. So,for example, a $10 coin contained the precise amount of gold or silver that wasequal to $10 in gold or silver by weight. Cheaters used to cut the edges off coins to meltthem down and make new coins for their own profit. Preventive measures had tobe taken. This was quite a serious issue since not every man could carry a pairof scales to check whether the coin was cut or had its proper weight.To tackle the cheaters tricks, it wasdecided to gouge small lines on the coin edges. Due to this they becamedistinguishable enough to tell if the coin was tampered with. This extraordinary method was suggested by thevery famous at that time and nowadays, physicist and Warden and Master of theBritish Royal Mint, IsaacNewton. The ideaseemed to be simple and brilliant at the same time. Eventually, all coins weremarked and swindles dropped to zero. And no wonder – when one came across coinwith smooth edges, they knew at once it had been cut or tampered with and wouldnot accept it. Now you know the rest of the story.
