在日本的铸币史上,和铜开(氵尔)乃开年号钱之先河。飞鸟时代的无文银钱和奈良时代的开基胜宝金币,堪称货泉之精品。宽永通宝尽管在其形制和铸造工艺等方面无特殊之处,但随着这种货币在我国的陆续出土,尤其是宽永通宝在北京展出后,更有专家学者撰文立论,进行深入地研究。笔者在此以浅陋之见,求教于大家。 In the history of coinage in Japan, and copper open (Seoul) is a precedent for the beginning of money. No money in the Asuka era and Kai-shek gold coins of the Nara period, can be regarded as the best of the goods. KuanTongTongBo despite its shape and casting process and so there is nothing special, but with the currency unearthed in our country one after another, especially after KuanTongTongbao was exhibited in Beijing, more experts and scholars wrote an essay in-depth the study. In this humble opinion, I seek advice in everyone.
