1.宝福局咸丰铁钱。史载宝福局咸丰大钱,除当五有铁钱外,均为铜钱。宝福局咸丰大钱从一十到一百,以厚重著名全国。但钱币史上均未注意到它含铁,也就是掺铁铸造铜钱。可见当时福建当局是“狡猾”的,这却成了如今鉴定宝福局咸丰大钱真伪的一个新的重要的手段,至今为止,伪品制作者尚未注意到这—点。不过,这类大铜钱含铁量均较少,一般只表现出微弱的磁性。只能吸附很小块的磁铁。其声、色、质均为铜品所属。现在我收集到此枚宝福局咸丰重宝一十大钱,褐色铁锈,声如铁,不及铜声清纯,重17克而能被磁铁吸起,即磁吸力超过钱重。大小文字均同于铜品,但背“一”字右有一点,工整而非流铁所致。此钱收集于闽北山区,面轮左上方有一“×”字小戳印,说明此钱经过社会认可流通。此钱属铁无疑,但属掺铁太多而至还是续铜钱后铸铁钱,尚未知。径36.5、穿6.5、厚2.5mm(图1) 1. Baofu Board Xianfeng iron money. History Bao Bao Fu Bureau Xianfeng big money, except when there are five ironclad money, are all coins. Bao Fu Xianfeng big money from a hundred to one hundred, with a heavy reputation of the country. But in the history of the coin did not notice that it contains iron, that is, iron casting coins. It can be seen that the Fujian authorities were “cunning” at the time, but this has now become a new and important means of identifying the authenticity of Xianfeng’s assets in the Baofu Bureau. Up to now, counterfeiters have not yet noticed this point. However, such large copper content of iron are less, generally only showed weak magnetic. Only a small piece of magnet can be adsorbed. The sound, color, quality are copper belong. Now I have collected this Bao Fu Board Xianfeng treasures ten big money, brown rust, sound such as iron, less than pure copper sound, weighing 17 grams and can be sucked by the magnet, that is, magnetic suction over the weight. The size of the text are the same as copper, but the back “a” right a bit, neat and not caused by iron flow. The money collected in the northern mountainous area, the top left of the noodles have a “x” small stamp, indicating that the money through the social recognition of circulation. This money is undoubtedly iron, but too much iron is added to or after the coin money cast iron, is unknown. Diameter 36.5, wear 6.5, thickness 2.5mm (Figure 1)
