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. A clipped coin would be easy to spot because the ridges, properly called a "reeded edge" would be worn away

Why are some US coins smooth and others with ridges?
Those ridges date back to when some U.S. coins were made of silver or gold. Without reeding (the ridges), it would be easy for someone to scrape off shavings of the metal to keep, and then the coin wouldn't contain its full value of metal content. Cents and nickels were of such low value and lacking precious metals that reeding was unnecessary.

A number of Delaware coins were minted with a so-called rotated die reverse. A die was incorrectly aligned in a press so some coins were minted with the back and front sides pointing the same direction (like Canadian coins) instead of 180 degrees off as is the standard for U.S. coins. This is considered to be a significant error and can retail for $50 or so.
