Ancient coins come in a wide variety of shapes and sizes. Rarely does one find a coin that approaches the perfect circular forms we are used to when thinking of modern coins.

We’ll look at three different setting types: bezel, prong and spinner.

The bezel setting: A Classic

A bezel setting is a type of setting used in jewelry to hold a gemstone in place. In a bezel setting, a metal rim or collar is formed around the edge of the gemstone, holding it securely in place.

In this coin, a denarius emperor Septimius Severus, both the front and back of the coin have a hammered bezel that keeps the coin in place. Some jewelry makers will use backplates to only have to bezel set one side of the coin. This creates the problem that now only one side of the coin is visible.

Bezel setting both sides of a coin allows for viewing of the entire coin, except for seeing the edge of the coin. To be able to see that, a prong setting is better suited.

The Prong Setting

A prong setting, on the other hand, is a type of setting that uses metal prongs or claws to hold the gemstone in place. The prongs are usually made of metal and are bent over the edges of the gemstone to hold it securely in place. Prong settings can have anywhere from two to six prongs, depending on the size and shape of the gemstone.

There are a few key differences between bezel and prong settings. One of the main differences is that bezel settings offer more protection for the coin, as the metal rim or collar surrounds the entire coin and provides added protection against damage. Prong settings, on the other hand, leave the edge of a coin exposed, which can make them more prone to damage.

Another difference between bezel and prong settings is the way they affect the appearance of the coin. Bezel settings tend to create a more streamlined and cohesive look, as the metal rim or collar surrounding the coin creates a smooth, continuous surface. Prong settings, on the other hand, can make the coin appear larger and more prominent.

Overall, the choice between a bezel and prong setting depends on the needs and preferences of the wearer. Bezel settings offer added protection for the coin and a more cohesive look, while prong settings can make it appear larger and more prominent.

The Spinner setting

Contrary to prong or bezel settings, a spinner setting allows for rotation of the coin. Not only does this type of setting provide an aesthetically pleasing result, it allows for viewing of both sides of the coin without having to take of the necklace.

A spinner setting can utilize both a bezel and a prong setting. Moreover, the outer ring of the setting - the part that holds the bezel or prong setting - could be half round, or fully round.

Another variable is the axis on which the coin rotates. This could be horizontally, vertically, or at any degree.

One complication of a spinner setting is that to get the full benefit of a spinner setting - to be able to view both sides of the coin with the right orientation, the coins aligments needs to be 180 degrees. If this is not the case, one side will look “right” while the other will look upside down when flipped.

For that reason, modern coins are after not good fits for spinner settings, if you care about the way the coin is facing.

The Ring setting

”Don’t buy damaged coins. They will be impossible to sell.” This is considered to be “some of the best advice” the written of an article in Coinweek received. For many reasons I do not agree.

I would never put a hole in a coin to create jewelry. However, there are many reasons why coins have holes. They could be pierced to be worn on clothing or another item. Collectors of coins tend to think that these ancient holes devalue the coin so much that they are not worth collecting unless they coin is exceedingly rare. I think the presence of a hole adds character. It tells us something about what happened to the coin after it was struck and circulated. Usually, we are left with no information at all.

Besides, a ring setting allows probably the most minimalist way to wear a coin. It furthermore revitalizes the coin to again be “used” in some way other than as currency.
