同治通宝是清代古币之一，清穆宗同治年间（1862年-1874年)铸造。同治通宝版式类似“康熙通宝”、 “乾隆通宝”，有苏、川、云、源、昌，桂等记局，但铸量较清朝前期钱已有大减。其中陕、济、伊、武、福、南、黔、广、晋、阿克苏等局的同治通宝仅见部颁样钱。

“同治通宝”于同治元年（1862年）正式开始铸行，但因铸钱亏损等因，铸造很不正常，常见的仅有“宝泉”(户部)、“宝源”(工部)、“宝苏”、“宝浙”、“宝昌”、“宝川”、“宝桂”和“宝东”等局，其余很少发现或仅见部颁样钱。“同治通宝”面文汉文宋体、楷书互见，各局所铸，大小、轻重参差不齐，一般径为22毫米左右，重约3克，铜质较差，铸工不精。

宣统通宝铜钱，制作工艺分两大类翻砂和机制,但早在光绪年就已经出现了机制钱币,制造了很多无孔小铜元,还有就是几枚就是由宝津局代制黄铜或红铜夹铅芯的样币,直径达4.7厘米制作颇为精美绝伦.但宣统通宝铜钱,以小铜钱占主位基本尺寸为径：机制的1.7厘米，薄片状。翻砂的1.2-2.5厘米,大钱反而少。这主要是因为在光绪后期市面基本上都使用铜元，在铸铜钱已无利可图。实际上铜钱已为象征性钱，或许铜元找零还需用些，但它必须是能体现出一枚铜元当十枚铜钱的可能。现从市面的一种“宝广”中圆孔“光绪通宝”﹑“宣统通宝”机制铜钱和“宝广”宣统通宝铸钱看明显减重。然也正反应出当时大清国力之不济。已到了崩溃的边缘。不知拿位好事者手雕这枚小银钱，钱面刀功可见。其径：1.8厘米强比通常宣统小铜钱大0.1厘米，宣统通宝

面中文字气息同一枚“宝广”铸的小钱较像，难能可贵的是满文“宝广”雕得非常精工，极不容易。然不认为它是铸厂雕钱，是因为：（1）钱面文字不精深，字有浮在表层之感。（2）内郭开口：它只是普通直开口，此口只有常用品才会马虎如此开法，此币市面根本未见过该钱使用，且穿郭也不匀。铸厂雕钱一般穿微决或郭呈弧形等等。此钱还有一种无法描述也说不出只凭收藏者多接触多见识才有的真伪那种感觉认定它。此小银钱虽为好事者戏雕之品，然不可否定，它也不失为品赏﹑把玩之佳品。

清朝最后一位皇帝的年号币，是中华五千年封建王朝的终结，是外圆内方古钱币的终结，是全面继承钱币文化记写社稷风云物刻铸`字体刻画达意`内涵丰富秘籍。是中华古钱币用艺术表白的最好的结速语。

Tongzhi Tongbao is one of the ancient coins of the Qing Dynasty. It was made during the reign of emperor Mu Zong of the Qing Dynasty (1862-1874). The layout of Tongzhi Tongbao is similar to Kangxi Tongbao and Qianlong Tongbao. There are Su, Chuan, Yun, yuan, Chang, GUI and other bureaus, but the casting amount has been greatly reduced compared with that of the early Qing Dynasty. Among them, Tongzhi Tongbao of Shaanxi, Ji'an, Yi, Wu, Fu, Nan, Qian, Guang, Jin, Aksu and other bureaus can only see the sample money issued by the Ministry.

Tongzhi Tongbao was officially cast in 1862, but because of the loss of money, the casting was very abnormal. The common ones were "Baoquan" (Ministry of household), "Baoyuan" (Ministry of work), "Baosu", "baozhe", "Baochang", "Baochuan", "Baogui" and "Baodong", and the others were rarely found or only seen“ Tongzhi Tongbao "face inscriptions can be seen in Chinese, song style and regular script. The size and weight of the surface inscriptions vary from bureau to bureau. Generally, the diameter is about 22 mm and the weight is about 3 g. the copper quality is poor and the foundry is poor.

Xuantong Tongbao copper coin can be made by two kinds of Technology: frosting and mechanism. But as early as Guangxu, mechanism coins have appeared, making many small copper coins without holes. There are also several samples made of brass or red copper with lead core by Baojin Bureau. The diameter is 4.7 cm, which is quite exquisite, It is thin. 1.2-2.5 cm of sand turning, but less money. This is mainly because in the late Guangxu period, copper coins were basically used in the market, and there was no profit in casting copper coins. In fact, copper coin has become symbolic money. Maybe it's necessary to change copper coin, but it must reflect the possibility that one copper coin can be used as ten copper coins. Now from the market of a kind of "Baoguang" in the round hole "Guangxu Tongbao", "Xuantong Tongbao" mechanism copper coin and "Baoguang" Xuantong Tongbao casting coin see obvious weight loss. However, it also reflected the poor national strength of the Qing Dynasty at that time. It's on the verge of collapse. I don't know if you can carve this small silver coin by a good person. You can see the power of the knife. Its diameter: 1.8 cm, 0.1 cm larger than the usual Xuantong small copper coin, Xuantong Tongbao

The characters in the face are similar to a coin made of Baoguang. It is rare that the carving of Baoguang in Manchu is very exquisite and not easy. However, I don't think it's a coin carved by a foundry because: (1) the characters on the surface of the coin are not profound, and the characters are floating on the surface（ 2) Inner opening: it's just an ordinary straight opening. Only common products can open this opening carelessly. This coin has never been used in the market, and it doesn't wear evenly. The coins carved in the foundry usually wear a tiny shape or a curved shape. There is also a kind of money that can not be described, nor can it be said that the authenticity of the money is determined only by the collector's more contact and more insight. Although this small silver coin is a good thing for those who do good deeds, it can not be denied that it is also a good thing to appreciate and play with.

The coinage of the last emperor of the Qing Dynasty is the end of China's five thousand year feudal dynasty, the end of the ancient coins of the outer circle and the inner square, the comprehensive inheritance of the coin culture, the writing of the country and the wind and cloud, the engraving of the characters, the depiction of the meaning and the rich connotation of the secret book. It is the best expression of ancient Chinese coins with art.
