Xianfeng Yuanbao, please follow the comments

Xianfeng Yuanbao should be one hundred and two pieces, please comment with friends. Today to tell you a real joke: our unit is a municipal state-owned enterprise, specializing in sulfuric acid, phosphate fertilizer. In the early 1980s, our factory tried to engage in copper sulfate, and the copper material was made of 2 tons of copper coins and copper coins. It is purchased from Hengyang and Changning at a scrap copper price of 5 yuan / pound. Grab it with a car grab and pour it into the sulfuric acid boiling furnace, that is hundreds of millions of copper coins, "the cub sells the field without heartache"! At that time, there was no sense of collection at all, and I believe that everyone laughed for a while first, and they wanted to cry after returning to God.

Please teach your friends, how are the above coins true or false? No need to talk about what value, thank you!
