The reason why silver plating is worthless is mainly because the gold plating process itself is worthless and the value of silver itself is not high. However, if it is ancient silver-plated jewelry, it may be relatively more valuable because it involves cultural relics and historical and cultural values.

In addition, the price of silver gilt is also related to its production process, age, rarity, appearance and other factors. For example, if it is silver-plated gold jewelry made in ancient times, the production process may be more elaborate, so the price may be higher. In addition, if the silver-plated gold jewelry is well preserved and in good condition, the price may be higher.

In a word, whether the silver gilt is valuable or not mainly depends on many factors, including technology, age, rarity, appearance and so on. Therefore, it needs to be considered comprehensively when determining its value.
