Those that survived are made valuable by their scarcity. The coins of the Taiping rebellion are an example. Most shops today sell Ching dynasty coins or commemorative coins of the ROC Another point worth mentioning is that, in the process of making coins, some defects slip through. These are not scorned as "deformed"; indeed they are of high value.
另外值得一提的是，錢幣鑄造的每一個過程，均經嚴密檢驗監督，但由於數量過多，仍難免出現「變體」或「錯體」的情形，這些錢幣非但不因「畸型」、「殘障」而被廢貶，一旦流出反而身價百倍，是錢幣收集者心目中的珍品。
