The 14k means that the plating is 14 karat gold. The "sgp" means that the item is silver with gold plating. What you have is a 14karat gold plated silver item. It is not gold, it is silver. The plating is not worth much, it's mainly for looks.
It dependes on the size of the object and the purity of the gold in the plating. The short answer is not very much.

Gold plating typically refers to a thin layer of gold that is applied to a base metal, and it is not measured in carats like solid gold. Instead, the purity of the gold used in plating is often indicated in karats (e.g., 10k, 14k, or 24k). The thickness of the gold layer can vary, but it is usually much less than what would be found in solid gold jewelry. For example, a common standard for gold plating is 14k gold, which means the gold content is 58.3% pure gold.
Gold plating at the jeweler is probably the best way to go.

"The most common gold plating solution includes some form of cyanide, and either alkaline gold or neutral gold."

It depends on what it is on, if it is gold on stainless steel or another base metal, not much, gold plating only puts a thin layer of gold on them, too little to be of any real value and requires costly removal to sell the gold. However, if it is gold plating over something like silver, it might have value, but rather for the sterling silver under the gold plating than for the gold plating.
