I spent 1500 in Yunnan and bought a 50g silver cup. The inner container is S990 of ancient Yunnan Silver. Did I exaggerate? Ask the great god to help explain.

According to the information you provided, you spent 1500 yuan to buy a 50g silver cup with an inner liner of S990, which is called Classical Drink. Generally speaking, classical silver is the traditional brand of silverware in Yunnan Province. Its product quality and manufacturing technology are relatively good, and it has certain value in the silverware market.

S990 refers to the silver content of the silver cup, that is, the main material of the cup is silver with purity of 99%. A 50-gram silver cup is relatively heavy, so it also has some value. However, the price of silver is relatively low, so the value of this silver cup is not as high as that of other precious metals such as gold or platinum.

To sum up, the 50-gram silver cup you bought with the ancient Yunnan silver S990 liner has certain value, but the specific value may need to be determined according to market conditions, manufacturing technology and other factors. If you are in doubt or uneasy about this purchase decision, I suggest you consult a professional jewelry or collectible appraisal institution to understand the true value and quality of the silver cup.
