What happens when a copper coin touches it?

With the hype of various collection themes in the market, some "common sense" has been constantly invented. For example, no one can touch the pendant after it is worn by the owner. It is purely a rumor! Imagine: if someone touches it, it will not work and become paper paste. How can we expect it to defeat the devil and protect your safety?

Not many people wear copper coins. I haven't heard of wearing any other coins except the two Buddhist coins of Kangxi, arhat money and Zhu Yuanzhang and Bao Tong. In addition, girls put san huang money, five emperors' money, six emperors' money and ten emperors' money in their bags. San huang's money is Qianlong Bao Tong, Daoguang Bao Tong and Jiaqing Bao Tong, which means that the money comes home, and evil spirits are behind it, so there is no saying that it is untouchable.
