A coin with these has 'reeded' edges.
Reeds were first put on the edges of coins back in the days when coins contained precious metals such as gold or silver. It was a common practice for crooks to shave off a tiny amount of metal all the way around the rim of a lot of coins, collect the shavings, and sell them to a metal dealer. However, shaving a coin with a reeded edge would immediately be obvious and the police or mint officials would know that someone was committing fraud.

The absence of ridges on some quarters is due to the coin's manufacturing process. Quarters without ridges are known as "smooth edge" quarters and are commonly found in uncirculated coin sets or special collector's editions. These quarters are legal tender and can be used just like regular quarters with ridges.

Nowadays, alongside size and shape, to help those with sight difficulties distinguish different coins. When coins were actually made of a precious metal they were there to prevent "clipping" or the practice of shaving a tiny bit of metal from the edge of the coin.
