Please tell me something about these four copper coins: five in Xianfeng and one in Song Huizong?

Your question, these four coppers: Xianfeng year coppers and five, Song Bao Tong and badges; Five baht is an old genuine product with a wide door, which is typical of the Han Dynasty. If you want to wear the small version of "1", the market price is generally around 20 yuan; Bao Tong in the Song Dynasty, a small version widely worn in the Song Dynasty, generally bid around 50 yuan in the market; Xianfeng heavy treasure, when five, is the format of Baoyuan Bureau, and the general bidding in the market is around 500 yuan; Xianfeng ingot, when 100, is the format of Baoquan Bureau. This is a modern high imitation, and the market generally bids around 30 yuan. Badges, in kind, are from the Republic of China, and the market price is generally around 200 yuan; If it has a certain collection value, it must be preserved!
