The milling is a throwback to times when coins were worth what they said they were. Many had smooth sides, because that was easier to mould using gold, silver, and most other metals. However, criminals and forgers would shave some of the coin off the rim. The difference was unnoticeable, and the shavings could be used to make more coinage, or simply be sold as a pure metal. Thus you had more money for the same amount of coins.
Milling makes it so unprofitable to first shave off the milling and then recarve or remould it that people simply don't bother. The advent of standard sized coins also helped make this a low concern.

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.
Quarters ad dimes, and lager denominations of coins, used to be made of silver, and a few of gold. The value of each coin was basically determined by the value of the silver or gold used to make it. Some people used to shave bits off each coin they received, thus accumulating valuable silver and gold for resale while reducing the real value of the coin being shaved. The milling on the edges was added so that you could tell if someone was trying to palm off on you a coin that had been shaved that way and was, therefore, not worth the amount marked on it.
