Best Answer

It's called "milling", and it's a historical relic.

At one time, coins were made of precious metals (gold or silver). Unscrupulous people would shave the edges of coins and collect the shavings to melt down. Milling the edges makes it obvious that this has been done, and that the coin therefore wasn't worth full value.

Neither quarters nor dimes still contain any gold or silver, but they're still milled, mostly because they've been that way for a long time, and ceasing to mill them would make them look "weird" to people at this point.

How many ways can you make 2.50 from quarters and dimes?

2.50 can be made up from 10 quarters or 25 dimes, for the first two ways. The smallest number of quarters that can be substituted for dimes without changing the sum is two, substituted for five dimes. Therefore, you can have: 20 dimes + 2 quarters, 15 dimes + 4 quarters, 10 dimes + 6 quarters, or 5 dimes + 8 quarters, four additional possibilities for a total of six..


Why are nickels and pennies smooth around the edges and quarters and dimes aren't?

The ridges on the edges of coins are called "reeds". Many years ago when quarters, dimes, and half dollars had silver in them, people would shave the edges, sell the silver, and still use the shaved coin for the face value of the coin. The mint added reeds so it could easily be determined if the coin was shaved or not.
