Abstract

The present paper presents the analytical study of an unusual Peruvian 1899 dinero coin whose authenticity has been questioned since the 1970’s. This coin, which is present in some numismatic collections although there is no record of having been minted officially, has been characterized using non-destructive techniques such as X-ray fluorescence (XRF), scanning electron microscopy coupled with energy dispersive spectroscopy (SEM–EDS), and X-ray diffraction (XRD). Results are consistent with a cast counterfeit coin made at the turn of the 19th and 20th using a copper base alloy that was silver-platted to pass unnoticed among the public. The alloy used, generally known as german silver, was common for counterfeits in North America and Europe in that period. The historical reasons for the appearance of this unexpected coin in Peru during a time of economic difficulties, where the public experienced a shortage of small-change coins, are briefly outlined.

对一枚1899年秘鲁货币的分析研究:揭开一枚未正式铸造的硬币的神秘面纱

本文介绍了一种不寻常的秘鲁1899年迪尼罗硬币的分析研究，其真实性自1970年代以来一直受到质疑。这枚硬币出现在一些钱币收藏中，尽管没有正式铸造的记录，但已经使用非破坏性技术进行了表征，例如x射线荧光(XRF)，扫描电子显微镜结合能量色散光谱(SEM-EDS)和x射线衍射(XRD)。结果与19世纪和20世纪初铸造的一枚假币一致，硬币使用的是镀银的铜基合金，以免在公众中被发现。所使用的合金，通常被称为德国银，在那个时期在北美和欧洲的假币中很常见。这枚出人意料的硬币出现在秘鲁的历史原因是在经济困难时期，公众经历了小面额硬币的短缺，简要概述。
