1848 $10 Coronet Head Eagle 90% Gold Set in 14k Yellow Gold Bezel

A $10 Coronet Head Eagle is a historic gold coin that was minted by the United States from 1838 to 1907. These coins are also commonly referred to as "Liberty Head Eagles" because of the design on the obverse (front) side of the coin, which features a left-facing image of Lady Liberty wearing a coronet inscribed with the word "LIBERTY."

Condition: Well Above Average For Time Period 

The coin was composed of 90% gold and 10% copper, with a total weight of 16.72 grams (0.48375 ounces of pure gold). These coins have a diameter of 27 mm and were designed by Christian Gobrecht.

The value of a specific $10 Coronet Head Eagle coin can vary based on factors such as its year of minting, condition, and rarity. Some years and mintmarks may be more valuable than others, and coins in excellent condition will generally be worth more than those in poor condition.

The 14k yellow gold bezel you mentioned is likely a decorative setting that surrounds the coin, allowing it to be worn as a pendant or used as jewelry. The value of the bezel itself would depend on its weight and design.

To determine the overall value of the set (coin + bezel), you would need to consider both the value of the coin and the value of the bezel as separate components. It's essential to have the coin evaluated by a professional numismatist (coin expert) to assess its specific value based on its characteristics.

Please keep in mind that the value of gold coins and their related jewelry can fluctuate with changes in the price of gold and the collector's market, so it's essential to get an updated appraisal if you plan to sell or insure your coin and bezel set.
