贞祐通宝

金宣宗名完颜珣（1163年－1224年）。1213年，纥石烈执中（胡沙虎）杀卫绍王后，拥立完颜珣为帝，改年号“贞祐”。

宣宗即位后，蒙古方面在发动强大军事进攻的同时，又不断遣使金朝，逼其投降。金宣宗迫于形势，不得不于贞祐二年（1214年）三月，派尚书右丞相承晖（完颜福兴）向蒙古求和，答应了成吉思汗提出的苛刻议和条件，并向蒙古献卫绍王女岐国公主并童男女各五百、绣衣三千件、马三千匹及大批金银珠玉。双方暂时达成和议，蒙古军队退出居庸关。当年五月，宣宗将金朝的都城从中都（今北京市）南迁到汴京（今河南省开封市）。

金宣宗的南迁，仅以重兵屯驻河南以自固，不顾北方州县的安危，因而大失人心，致使驻守在东北的金朝将领和汉族地主与金朝分裂，他们为了保存自己而降附蒙古。贞佑二年（1214），锦州（今属辽宁）张鲸、张致兄弟聚众十余万叛金，杀节度使自称王，在木华黎率蒙古军攻入东北后也降附蒙古。在此之前，契丹人耶律留哥叛金，与蒙古军联结，自称辽王，成为蒙古军攻占东北地区的帮手。贞佑三年（1215）女真人辽东宣抚蒲鲜万奴叛金独立，建立大真国，改元天泰，称天王。金朝在东北的统治已分崩离析。

蒙自保，并反抗金朝的统治，到处团结起义，形成了声势浩大的红袄军大起义。最初，以山东杨安儿、李全等抗金的起义军为中心，很快扩展到河北、河南、山西等地。宣宗调集兵力镇压起义军，但各地起义军前仆后继，连绵不断，沉重地打击着金朝统治集团。

元光二年十二月（1224年1月），在金朝处于内外交困，国势日衰之时，金宣宗忧郁成病而死，终年61岁。

金宣宗是金国第八位皇帝，经历过贞祐、兴定、元光三个年号，在位11年，史称金宣宗。

“贞祐”钱配合贞佑钞发行，有小平、折二和折五三种，总计行用四年，系金宣宗早期铸币，见证过硝烟弥漫的“中都之战”（金国与蒙古的战争），存世均少，弥足珍贵。

After Xuanzong ascended the throne, while launching a powerful military attack, Mongolia continued to send envoys to the Jin Dynasty to force it to surrender. Forced by the situation, in March of the second year of Zhenyou (1214), Jin Xuanzong had to send Chenghui (Wanyan Fuxing), the right Prime Minister of the Minister of justice, to seek peace with Mongolia, agreed to the harsh negotiation conditions put forward by Genghis Khan, and presented to Mongolia 500 princesses and children of nuqi country, king of Shaoxing, 500 men and women, 3000 embroidered clothes, 3000 horses and a large number of gold, silver, pearls and jade. The two sides temporarily reached a peace agreement and the Mongolian army withdrew from Juyong Pass. In May of that year, Xuanzong moved the capital of the Jin Dynasty from Zhongdu (now Beijing) to Bianjing (now Kaifeng City, Henan Province).

Jin Xuanzong's southward move only settled in Henan with heavy troops to consolidate himself, ignoring the safety of northern prefectures and counties. Therefore, it lost people's hearts. As a result, the Jin Dynasty generals and Han landlords stationed in the Northeast split from the Jin Dynasty. They surrendered to Mongolia in order to preserve themselves. In the second year of Zhenyou (1214), the brothers Zhang Jing and Zhang Zhi of Jinzhou (now Liaoning) gathered more than 100000 rebels to kill Jiedushi and claim to be the king. After Muhua Li led the Mongolian army into the northeast, they also fell to Mongolia. Prior to this, the Khitan jeruligo rebelled against Jin, connected with the Mongolian army, claimed to be the king of Liao, and became a helper for the Mongolian army to capture the northeast. In the third year of Zhenyou (1215), the immortal Liaodong declared that Puxian and wannu rebelled against Jin for independence, established the Dazhen country, changed the yuan Tiantai, and was called the heavenly king. The rule of the Jin Dynasty in the Northeast has disintegrated.

Mongolian self-protection, and resistance to the rule of the Jin Dynasty, everywhere United uprising, forming a massive red coat army uprising. Initially, it centered on the anti gold rebels such as yang'an'er and Li Quan in Shandong, and soon expanded to Hebei, Henan, Shanxi and other places. Xuanzong mobilized troops to suppress the rebels, but the insurgents continued to attack the ruling group of the Jin Dynasty.

In December of the second year of Yuanguang (January 1224), when the Jin Dynasty was in difficulties at home and abroad and the national power was declining, Jin Xuanzong died of depression and illness at the age of 61.

Jin Xuanzong is the eighth emperor of the state of Jin. He has experienced three years: Zhenyou, Xingding and Yuanguang. He has been in power for 11 years and is known as Jin Xuanzong in history.

"Zhenyou" coins are issued together with Zhenyou banknotes, including Xiaoping, discount 2 and discount 5. They have been used for a total of four years. They were coined in the early days of Emperor Xuanzong of Jin Dynasty and witnessed the "battle of Zhongdu" (the war between Jin and Mongolia). They are rare and precious.
