This coin, minted during the reign of Emperor Gaozong of the Southern Song dynasty, is a “Jianyan Tongbao” coin, characterised by inscriptions in the regular script style. The script remains relatively clear despite some wear.

The coin is a typical square-holed coin, with a square hole at the centre of the obverse. The obverse side features the four characters “Jianyan Tongbao” in regular script, though the inscriptions show slight signs of erosion. A noticeable crack is present in the lower left quadrant of the obverse, and the outer edge exhibits minor damage. The reverse side of the coin also has a central square hole, with several flaws visible along the outer edge. Overall, the surface condition of the coin is uneven on both sides.

The “Jianyan Tongbao” coins were minted during the Jianyan era (AD 1127-AD 1130) of Emperor Gaozong’s reign, a period marked by the transition of power and the Southern migration of the Song court. Despite these upheavals, the minting of coins continued uninterrupted, with many mints remaining active in producing currency. Among the various types of “Jianyan Tongbao” coins, those featuring regular and seal scripts are most common.

Furthermore, extant “Jianyan Tongbao” coins can be categorised into “one cash,” “two cash,” and “three cash,” with “two cash” being the most prevalent among surviving specimens. The denomination of the coins can be distinguished by their size and weight. According to existing data, standard “one cash” coins have a diameter of approximately 25 mm and weigh around 3.5 g; “two cash” coins have a diameter of about 28 mm and weigh around 5.7 g; and “three cash” coins have a diameter of about 30 mm and weigh approximately 9.3 g.

This “Jianyan Tongbao” coin has an approximate diameter of 30 mm and a weight of 5.1 g, showing a slight deviation from the standard specifications for a “two cash” coin. While its size corresponds to that of a “three cash” coin, the significant difference in weight suggests that it is more likely to be classified as a “two cash” coin.

這枚錢幣是南宋高宗時期鑄造的「建炎通寶」，其特色是幣面文字採楷書風格，字體尚稱清晰。

這是一枚方孔錢。錢幣的正面中央有一方孔，幣面有楷書「建炎通寶」四字，但字跡都有些微磨蝕痕跡。幣面左下方有一明顯的裂痕，外圈有些微殘缺。錢幣的反面中央也有一方孔，外圈也有不少瑕疵。整體而言錢幣正反面成色皆不均勻。

建炎通寶鑄造於南宋高宗建炎年間(公元1127-1130年)，此時正值政權遞嬗、宋室南遷的階段，不過此時鑄錢工作卻未見停歇，反而有多數錢監持續進行製錢工作。而在眾多的建炎通寶中，以楷書、篆書字體為多。

另外，在傳世的建炎通寶中，可分為小平錢、折二、折三錢，其中傳世錢幣中又以折二錢為最。面額大小區分的方式主要可從尺寸、重量辨別。依據現有資料顯示，標準小平錢直徑約為25毫米左右，重量約3.5克左右；折二錢直徑約28毫米左右，重量約5.7克左右；折三錢直徑約30毫米左右，重量約9.3克左右。

這枚建炎通寶的尺寸約略為直徑30毫米，重量5.1克，與標準折二錢存在些許誤差。雖然其尺寸與折三錢相符，但由於重量巨大差距，故面額較可能為折二錢。
