Copper coins should not be abolished completely as they serve a useful purpose in everyday transactions, especially for small purchases or in situations where electronic payment methods are not available. However, it may be worth considering reducing the production of copper coins and encouraging the use of higher denomination coins or digital payments to reduce the cost of producing and handling these coins. Ultimately, a balance should be struck between the practicality of using copper coins and the cost associated with their production and circulation. **

Copper coins are magnetic because they are typically coated with a thin layer of nickel or zinc, which are magnetic metals. This coating allows the coins to be easily detected and sorted by vending machines and coin counters. On the other hand, copper sheets are not magnetic because they are pure copper and do not contain any magnetic materials. The lack of magnetic properties in pure copper makes it non-magnetic, unlike the coated copper coins. **

Copper coins turn turquoise due to a process called oxidation. When copper comes into contact with oxygen and moisture in the air, it forms a layer of copper oxide on its surface. This copper oxide layer is what gives the coins their turquoise color. Over time, this layer can continue to develop and change in color, giving the coins a unique patina. **
