The easiest coins to collect are sets of coins currently in circulation. But even then it can be tough: for example, the old aluminum two chiao (one chiao being one tenth of an NT dollar) and copper five chiao are not easy to find.
目前比較容易蒐集的是「現行硬幣硬輔幣整套」，自民國三十八年起總共三十九枚，雖說是較容易，但事實上也有困難，比如二角鋁幣及五角銅幣就不易找到。
