How many ridges does a dime have? If you’ve ever taken a close look at a dime, you may have noticed the tiny grooved lines along the coin’s edge. These ridges are an important security feature of the dime that also impacts how the coin feels and sounds when handled.
But have you ever wondered exactly how many ridges or reeds a dime has? In this comprehensive guide, we’ll take a close-up look at the intricate details of the US dime to answer that question and more.
If you’re short on time, here’s a quick answer to your question: the current dime has 118 reeds or ridges along its edge.
The History and Purpose of Reeding on Coins
Reeding refers to the ridges or grooves that are present on the edges of some coins. These ridges serve both a historical and practical purpose, adding depth and texture to the overall design of the coin while also serving as a deterrent against counterfeiting.
When and Why Reeding Was Introduced
Reeding was first introduced on coins in the early 1790s in the United States. The practice began as a way to prevent fraud and counterfeiting. At the time, counterfeiters would often shave down the edges of coins made from precious metals like gold and silver, and then use the shavings to create new coins.
By adding ridges to the edges, it became much more difficult for counterfeiters to recreate the intricate details of the coins.
Additionally, reeding served as a means of standardization. Before the introduction of reeding, the size and weight of coins varied, making it easier for counterfeiters to pass off their fake coins as genuine.
The addition of reeding allowed for a consistent and easily recognizable feature that could be used to distinguish real coins from counterfeit ones.
How Reeding Helps Prevent Counterfeiting
The presence of reeding on a coin makes it more difficult to tamper with or alter the coin’s edges. The ridges create a distinct pattern that is not easily replicated, making it easier for individuals and businesses to identify counterfeit coins.
Additionally, the ridges make it more challenging to shave down the edges of a coin without visibly altering the reeded pattern.
Reeding is just one of the many anti-counterfeiting measures that modern coins employ. Other security features include raised edges, holograms, micro printing, and specialized inks. Together, these measures help to ensure the integrity of the currency and protect against counterfeiters.
Key Details About the Modern US Dime
Year the Current Design Was Introduced
The current design of the US dime, featuring President Franklin D. Roosevelt on the obverse and a torch, an olive branch, and an oak branch on the reverse, was introduced in 1946. This design was created by John R. Sinnock and has remained largely unchanged since then.
It is worth noting that before 1946, the dime featured a design known as the “Mercury dime,” which depicted Liberty wearing a Phrygian cap.
Dimensions and Metal Composition
The modern US dime has a diameter of 17.91 millimeters and weighs 2.268 grams. It is composed of a cupronickel blend, consisting of 91.67% copper and 8.33% nickel. This composition gives the dime its characteristic silver appearance.
However, it is worth mentioning that dimes minted before 1965 were composed of 90% silver and 10% copper, giving them a higher intrinsic value.
The Minting Process
The minting process for dimes involves several steps to ensure their quality and consistency. The first step is the preparation of the blank planchets, which are typically made from strips of metal that are punched to the correct diameter and thickness.
These planchets are then cleaned and polished to remove any impurities.
Once the planchets are ready, they are fed into a coining press, where the design and inscriptions are stamped onto both sides of the coin. The press exerts immense pressure to transfer the design onto the planchet, resulting in a precise and detailed impression.
After the coins are struck, they are inspected for any defects or imperfections before being packaged and distributed to banks and other financial institutions.

Examining the Ridges on the Dime’s Edge
Total Number of Ridges
Have you ever wondered how many ridges a dime has? Well, the answer might surprise you! A standard dime in the United States has a total of 118 ridges on its edge. These ridges serve a purpose beyond just aesthetics – they help the visually impaired to identify the coin by touch alone.
The ridges on the dime are relatively small and closely spaced, making it easier for those with impaired vision to distinguish it from other coins.
Spacing Between Ridges
The spacing between the ridges on a dime is designed to be uniform, allowing for easy identification and counting. If you take a closer look at the edge of a dime, you’ll notice that the ridges are evenly spaced, creating a pattern that is not only visually appealing but also functional.
The spacing between the ridges is approximately 0.085 inches, providing a consistent and tactile experience for those who rely on touch to differentiate between coins.
Uniformity of Ridges
When examining the ridges on a dime, you’ll find that they are remarkably uniform in both size and depth. This consistency is essential in ensuring that individuals with visual impairments can reliably identify the coin.
The ridges must be distinct enough to be easily felt, but not so deep that they become prone to wear and tear. The United States Mint takes great care in crafting each dime, ensuring that the ridges meet the necessary standards for both functionality and durability.
For more information about the ridges on a dime, you can visit the United States Mint website, where you’ll find detailed information about the design and production of coins. So, next time you come across a dime, take a moment to appreciate the thought and precision that goes into its design – those ridges serve a significant purpose!
The Sound and Feel of a Reeded Edge
Have you ever wondered why a dime, or any other coin for that matter, has ridges on its edge? These ridges, known as a reeded edge, serve several purposes. One interesting aspect of the reeded edge is the sound it produces when the coin is dropped or rubbed against another surface.
Additionally, the texture of the ridges provides a unique tactile sensation when handling the coin. Let’s take a closer look at the acoustic properties and tactile sensation of a reeded edge.
Acoustic Properties
The ridges on a dime’s edge play a significant role in the coin’s acoustic properties. When a reeded coin is dropped onto a hard surface, the ridges create a distinct sound that is different from that of a smooth-edged coin.
The ridges cause the coin to create more friction as it falls, resulting in a louder and more noticeable sound. This feature is particularly useful for visually impaired individuals, as they can rely on the sound to differentiate between different denominations of coins.
Furthermore, the sound of a reeded edge can be used as a diagnostic tool to determine the authenticity of a coin. Counterfeit coins often lack the proper ridges, resulting in a different sound when dropped.
Numismatists and collectors are trained to identify the specific sound produced by genuine coins, ensuring the integrity of their collection.
Tactile Sensation When Handling
In addition to its acoustic properties, the reeded edge of a dime offers a unique tactile sensation when handling the coin. The ridges provide a textured surface that allows for a better grip, making it easier to hold and manipulate the coin.
This feature is particularly useful for vending machines or coin-operated devices, as the ridges help prevent slippage and ensure a smooth transaction.
Moreover, the tactile sensation of a reeded edge adds to the overall experience of handling coins. It gives a sense of authenticity and tradition, reminding us of the rich history behind these small pieces of currency.
The ridges on a dime’s edge are a small but significant detail that contributes to the enjoyment of numismatics and the appreciation of coin design.
