第五版百元人民币继承了我国印制技术的传统经验，借鉴了国外钞票设计的先进技术，不仅有实用价值，而且具有很高的艺术价值，具有不可取代的价值地位且升值空间巨大。水印是钞票纸的一个重要组成部分，是钞票的主要防伪措施之一。
此一张独一无二的2005年版的错版币，此张错版币有一处错误为：在光线下我们可以清晰看到，这张钱币的主席头像水印与正常的一百元的水印不一样，此张钱币的水印有二个毛主席印象，重复印刷了，以及有二个100元的水印，这与正常的100元人民币不同观感的地方直接反映了这张钱币是非同寻常的，具有很高收藏价值。
在日常生活中，错币也被叫做残次币。由于错版人民币并非假币，也是可以在日常生活中流通使用的，所以错版人民币在一定程度上是存在的。错版人民币一直是民间收藏市场的“稀缺品”，它的稀有性让其成为收藏领域的一朵奇葩。作为特殊商品，不论持有者是收藏爱好者或者是普通拥有者，它始终成为持有者的财富。这就赋予了错体币的价值属性。
The fifth edition of 100 yuan RMB inherits the traditional experience of printing technology in China and draws on advanced technology in foreign banknote design. It not only has practical value, but also has high artistic value, an irreplaceable value position, and huge appreciation space. Watermark is an important component of banknote paper and one of the main anti-counterfeiting measures for banknotes.
This unique 2005 edition of the wrong version of the coin has an error: under light, we can clearly see that the watermark on the portrait of the chairman of this coin is different from the normal watermark of 100 yuan. The watermark on this coin has two impressions of Chairman Mao, which are reprinted, and there are two watermarks of 100 yuan. The difference in appearance from the normal watermark of 100 yuan directly reflects that this coin is extraordinary and has high collection value.
In daily life, incorrect currency is also known as defective currency. Due to the fact that the wrong version of RMB is not a counterfeit currency and can also be circulated and used in daily life, there is a certain degree of existence of the wrong version of RMB. Wrong version RMB has always been a scarce commodity in the folk collection market, and its rarity has made it a rare flower in the collection field. As a special commodity, whether the holder is a collector's enthusiast or an ordinary owner, it always becomes the owner's wealth. This endows the wrong currency with value attributes.
