现在流通纪念币的收藏价值，越来越多的人共知了，正因为其美学价值及收藏价值， 流通纪念币的伪仿产品也越来越多了，所以，辨别纪念币真假成为一个问题！
流通纪念币制作精湛、图案美观、寓意深远，具有极高的美学价值和收藏价值。然而，随着流通纪念币的连年发行及市场价格逐步走高，一些不法之徒视国家法律于不顾，铤而走险，牟取暴利，大量制假贩假。目前流通纪念币板块中大部分都有赝品。值得一提的是“香港回归”、“澳门回归”、“建国50周年”双金属纪念币也能造假，制假者已达到登峰造极的水平。广大收藏爱好者，在选购纪念币时，只要仔细观察，或用真币对照，赝品“庐山真面目”将会暴露无遗。
从整体特征来看，一是赝品做工粗糙，成色不足，颜色不一，黄色币发白、发亮，白色币显黄，这是赝品金属搭配比例不当所因有的特征；二是正、背面图案略显模糊，没有真币那样有层次感和立体感，显得呆板，仔细观察有“形同而神不似”的感觉，在放大镜下，图案有明显的沙粒状结构，光泽和亮度均不及真币。赝品字体略粗，笔划欠规范，棱角、国徽、天安门图案欠分明，五个门洞和十根柱子比较模糊，天安门前的华表没有立体感，有的只能看到一座、有的甚至全无；三是赝品重量参差不齐。下面将对《中国人民银行建行40周年》纪念币赝品别作一介绍，仅供广大钱币收藏爱好者参考。
《中国人民银行建行40周年》纪念币 此币发行于1988年12月1日，发行量206.8万枚，直径30mm，重9.3克，铜镍合金结构，面值1元，全套1枚，正面图案；国徽、国名、年号；背面图案，中国人民银行行徽及总行大厦，设计者；余敏，白文均，上海铸造厂铸造。真币从感观上洁白光亮，铸工精致，手摸光滑，正背面图案文字轮廓清晰。用放大镜观察边齿均匀，错落有致，背面总行办公楼墙体和中心楼线条垂直，疏密一致，屋顶二个方块匀称，圆形中心楼顶部光亮有立体感；麦穗纹路清晰，天安门前的华表、中文、年号及符合清晰而有立体感，五角星凸感强。
假币从感观上灰白带有淡黄铜色，手摸粗糙，有的还会刮手，重9.633克，比真币重0.333克，边饰不均匀，内圆有偏心、厚薄不一；背面“中国人民银行成立四十周年”“银”字第三笔与第一、二笔相联，周年的“周”字中间的“吉”字笔划不清楚，有的相连，总行办公楼和中心楼墙体线条明显不直且粗细不一，有拥挤感，屋顶二个方块大小不一，不均匀，左边小方块不方正，左角有尖峰状。凹下部分发亮；圆形中心楼顶部凹下部分有明显砂眼和微小气泡，真品银白色，赝品阴暗色；正面国徽麦穗纹路不清，手摸有凹陷感，天安门前的华表没有立体感，有左无右，有右无左，有的只有半节，有的甚至全无，中文文字缺乏力度和立体感，五角星凸感不强，显得粗笨，这种现象是造假者翻砂脱摸时用力不匀所致。
当大家都知道如何辩别流通币真假时，那么假流通币也就没有生存机会了。
