Reeded Edge

Definition

Reeded Edge is a decorative technique used primarily in coin and medal production, characterised by a series of vertical grooves or ridges along the edge of the item. This design not only enhances the aesthetic appeal but also serves a functional purpose by preventing wear and tear, as well as deterring counterfeiting. The reeded edge creates friction, making it more difficult to smooth out the edge without leaving noticeable marks.

How It’s Used in the Industry

In the minting process, the reeded edge is applied after the coin or medal has been struck. First, a blank metal disc, known as a planchet, is created. The planchet is then struck with a die, which imprints the design on the face. After this, the planchet passes through a reeding machine, which engraves the vertical grooves into the edge. This step is crucial for both aesthetic and security reasons, as it makes the item more difficult to alter or counterfeit. Finally, the finished product is polished and prepared for distribution.

History & Origins

The concept of the reeded edge dates back to the late 17th century, with its earliest uses found in coins minted in England. The introduction of reeded edges was primarily a response to the widespread practice of “clipping,” where individuals would shave off precious metal from the edges of coins. By adding grooves, mints aimed to deter such practices and maintain the integrity of their currency. Over time, the technique became widely adopted in various countries, evolving into a standard feature for many modern coins and medals.

Variations & Related Terms

There are several variations of the reeded edge, including the smooth edge, which lacks any grooves, and the lettered edge, which features inscriptions or designs along the edge. Additionally, some coins may have a combination of reeded and smooth edges, known as a “milled edge.” Other related terms include “finishing” and “edge lettering,” which refer to different techniques used to enhance the appearance and security of coins and medals.

Modern Applications

Today, the reeded edge is commonly found on various currencies, including coins such as the U.S. quarter and the British pound. Beyond currency, reeded edges are also used in awards, medals, and decorative items, adding a classic touch. The technique remains relevant in modern minting processes, utilising advanced technology to ensure precision and consistency. Additionally, collectors often seek out coins with reeded edges for their aesthetic and historical value.

Practical Tips & Products

When purchasing coins or medals with reeded edges, look for items from reputable dealers to ensure authenticity. If you’re a collector, consider investing in protective cases to prevent wear on the edges. Additionally, familiarise yourself with grading systems to assess the quality of reeded-edge coins, as condition can significantly affect their value.
