The actual term is "reeded" rather than "notched". Reeded edges were once used to prevent thieves from clipping coins, that is, shaving metal from the edges where it wouldn't be noticed.
If you're referring to US Coins, all former silver and gold coins had reeded edges to prevent clipping of those precious metals.
Today dimes, quarters, and half dollars are reeded simply because their designs haven't been significantly changed since the days they were made of silver. The brass $1 coins introduced in 2000 are a new size and design, and have smooth edges to help differentiate them from the other denominations.
Many countries now use variations of standard reeding to help make their coins distinguishable by touch as well as sight, especially if they're similar in size. For example some euro coins have wide reeding, others have very narrow reeding, and still others have what's called "interrupted" reeding with interspersed smooth spaces.

Why are the edges of some coins notched?
The actual term is "reeded" rather than "notched". Reeded edges prevent thieves from clipping coins. That is shaving metal metal off the edges. Dimes, quarters, half-dollars, and dollar coins all were made of silver until 1964. Pennies and nickels do not have precious metal in their mix. The US continued to use reeding on the edges of dimes, quarters, and half dollars even though they were changed to copper-nickel in the 1960s and 1970s. The $1 coins introduced in 2000 are also made of non-precious metals, and have smooth edges to help differentiate them from the other denominations. Many countries now use variations of standard reeding to help make their coins distinguishable by touch as well as sight, especially if they're similar in size. For example some euro coins have wide reeding, others have very narrow reeding, and still others have what's called "interrupted" reeding with interspersed smooth spaces.

Why do some coins have smooth edges and others have ridged edges?
Coins with smooth edges often represent a simpler design or are meant to signify a lower denomination, while ridged edges, or reeding, serve several purposes. The ridges help prevent counterfeiting by making it more difficult to shave off metal without detection. Additionally, they enhance grip and handling, making it easier for users to recognize and differentiate coins, especially in larger quantities.
