The "MCO" stamped on the gold chain necklace likely indicates the manufacturer or designer's mark, which can help identify the brand or origin of the piece. The "1 20" refers to the gold content, indicating that the chain is made of 14 karat gold, with 1/20th of the item’s weight being solid gold. This means the necklace is a blend of gold and other metals, ensuring durability while maintaining a certain level of gold purity.

In the context of jewelry, "MCO" typically stands for "Manufacturing Company." The inscription "120 14K MCO" indicates that the gold chain necklace is made of 14-karat gold and has a weight of 120 units, likely referring to a measurement in milligrams or a specific length. This marking helps identify the piece's quality and origin.
If the necklace is silver it means it was made using Sterling silver.
The letters "NC" stamped on a 925 silver chain necklace typically stand for "Nickel Content." This indicates that the silver may contain a certain percentage of nickel, which is often added to strengthen the metal. However, it’s important to note that if someone has a nickel allergy, they should be cautious with items marked this way. The "925" refers to the purity of the silver, meaning it is 92.5% pure silver.
I had the same thing stamped on my 10k gold necklace. I called a jeweller and they weren't very helpful but they told me it was most likely the brand name.
