and sold for profit. this practice drained resources from the economy and devalued the coins in circulation. coin clipping became a widespread issue that led to a loss of confidence in currency, as people began to doubt the true value of the money in their possession. to combat this growing issue, governments began using machines to add ridges to coin edges, making it obvious when a coin had been tampered with. this simple but effective design change marked a turning point in currency security, and today, those ridges remain a subtle but effective security measure against fraud. what is the central idea of the passage? governments have used a variety of methods over the years to discourage fraud. ridged edges on coins were developed to help prevent tampering with currency. traditional gold and silver coins are more valuable than modern coins used today. gold and silver coins were often defaced so their scraps could be sold for profit.

Answer

Brief Explanations:

The passage starts by describing coin - clipping as a fraud issue and then focuses on how governments added ridges to coin edges to prevent tampering. It doesn't discuss a variety of fraud - discouraging methods in general, nor does it compare traditional and modern coins' value or just focus on defacing coins for profit. The main point is about the development of ridged edges on coins to prevent currency tampering.

Answer:

Ridged edges on coins were developed to help prevent tampering with currency.
