The copper bracelet left by the old man is worthless. The value of copper products is relatively low, unless they are antiques or rare treasures. Normal copper products can only be sold for tens or hundreds of yuan in the market, and because of the characteristics of copper, it is easy to be oxidized and corroded in daily use, and it needs to be processed to maintain its beauty.

If this copper bracelet is an antique or a rare treasure, its value may be higher. But if it is ordinary copper products, its value is limited. If you want more detailed information, or want to sell this copper bracelet, I suggest you consult a professional jewelry or antique appraisal agency or auction house.
