北宋貨幣大觀通寶，是由徽宗御題錢文。宋代與歷朝有所不同，每換一種年號就開爐鑄新幣，若年號與寶文相重，則更鑄非年號錢。終宋三百年，通行以小平折二錢為主，其間也有大錢流通、錢幣的輪廓，尺寸都有一定標準。因此宋錢版別極多，歷代罕有，錢文除真、草、隸、篆，行外，還有便是北宋徽宗的“玉劃銀勾”瘦金體。

厚度適中，這枚錢幣包漿自然，底光柔和，所謂包漿是自然形成的氧化層，也有人為手盤包漿，兩者不同，但同時都有保護錢幣的功能，有如給錢幣鍍上一層保護膜，使錢幣不再氧化，便於收藏傳世，如果覺得錢幣髒，可以用清水洗，再用棉布擦乾，不要破壞包漿，破壞了包漿就相當於破壞了保護層，更重要的是包漿是鑑定新老錢幣最簡單有效的方法。細看這枚錢幣品相完美，沒有磕缺，損毀，變形等是不可多得的收藏級錢幣，建議收藏，傳世。
