Taiwan's NT$10 coin survived one of the stranger identity crises in modern numismatics: the Republic of China government, exiled to Taiwan since 1949, continued issuing coins under the ROC calendar year system — meaning this piece carries a year count reckoned from the founding of the Republic in 1912, not the Gregorian calendar. A coin dated "70" is 1981; "99" is 2010. Collectors unfamiliar with the Minguo calendar system routinely misdescribe these dates.
