How many ridges does a dime have?


Answer by  MarkWatrous (729)

The "ridges" that you are referring to are actually called "reeds". All dimes that are in circulation have 118 reeds. The number of reeds was established when the dime was commissioned by the Coinage Act of 1792. The first dime was minted in 1796 and continues to be produced today.

The US dime has 118 ridges around it's circumference. These ridges, also known as a reeded edge, were originally used as a counterfeit prevention tool. They are also useful to the seeing impaired for identifying the coin.

A dime has 118 ridges. A short cut to verify this is by counting half way down the edge of a dime, and multiply that number by 2.
