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.
Yes it has one syllable.
Arrange them in the shape of a square with 4 on the left, 4 on the right, 4 across the top, and 4 across the bottom. The coin in each corner counts as a member of two edges. Each edge has 4 coins in it, and there are a total of 12 coins all around the square.
A cube has twelve edges.

All coins have edges.
A cancerous mole may have ragged or notched edges.
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.
Coins have smooth edges to make them easy to stack and handle. Rough edges, also known as reeded edges, are added to coins as a security feature to prevent counterfeiting by making it difficult to file down or alter the edges of the coin.
Yes they do.

It prevented thieves from shaving off precious metal from around the edges of coins.
Reeding the edges of coins began to prevent "shaving". Early coins were made from gold and silver and the grooves were added to stop people from filing down the edges to recover the precious metals. Reeded coins go as far back as the 1820's.
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.
Please stop by a bank and ask them for some other $1 coins. All "golden" dollars have smooth edges to make them more identifiable to people who are blind or have limited vision. The coins' smooth edges make it easier to tell them apart from quarters and half dollars when touched.
