精品推荐—清代泰谷银锭

银锭是熔铸成锭的白银。目前出土银锭中年代最早的，是汉景帝中元二年(公元前148年)所铸。汉武帝元狩四年(公元前119年)作白金(即白银)三品。王莽铸有银货二品。其后历代皆有铸造，惟流通不广。隋唐以前称银锭为“银饼”、“银铤”，称扁平形银币为“钣”、“笏”、“版”，棒形的称“铤”、“挺”，宋以后改称“银锭”。元代于银锭之外总称“元宝”，形式变为马蹄形，故亦称“马蹄银”。明清两代均沿用“元宝”一词。

氧化蜂窝孔：此银锭底部有明显的氧化蜂窝孔，呈现大小不一的凹痕，这是由于银锭是由不同金属合金制成，其中的锡元素在极低的温度下会变成粉末，这就造成了与银锭中的银元素渐渐产生了分离，也就有了这枚氧化蜂窝孔的现象，不过锡要在零下13.2摄氏度，才会产生反应，有了这些痕迹无疑是开门的老银锭，不用怀疑真假，目前还无法仿制这大小不一的蜂窝孔。

白银的颜色白润而沉稳，银锭气孔中有金黄色的多彩宝光，银锭本身色彩为雪白色，老银锭由于在使用或埋入土中,受人们触摸、氧化等损伤，银锭已自然生成了一层银锈和包浆，这种银锈和包浆的颜色大多为灰色或灰褐色，色泽温润。民间对白银鉴别银色有很多口诀，这里介绍含黄铜和红铜的两个口诀。含有黄铜的银色为“七黑八灰九转青，九五成时色还清”，含红铜的银色口诀为“七黑八红九带白，九五成时还原色”。银锭的成色(即含银量)都基本在90%-93%，含铜4%-5%，含锡1%-2%银锭的颜色除有包浆外，都应是雪白色的发出宝光，可见此银锭年代久远，包浆厚重。
