Correction on my post about "traditional Chinese in Taiwan." Newpapers are written top right to bottom left. Exactly opposite to western writing. They traditionally start at what we would consider the back of the book, and write forward page by page. The western format is becoming increasely more common in Chinese books. Of six of my wife's books, two have western formats and four traditional Chinese formats for her Chinese books [front to back], and inside has same format as page format.
Question was reading dates on Chinese coins. Was shown what the character for "year" is and if is read left to right or right to left. China is left to right (in a western style), Taiwan is right to left (in more traditional style as is older Chinese coins).
To my understanding Krause is correct on these dates. They match all the collective dates of Western and Republic of China Dates that I have seen on coinage. All current NT$50 in circulation has both Western & Republican dates. Suggest with your superior knowledge and "the world that you're from" [unlike the world you said I was from] that you write Krause and The Republic of China in Taiwan to point out their error. I'm sure that is your only alternative since changing your mind is not an option it seems.
