The characters read from right to left and top to bottom, even on new Taiwanese coins." closed quote @Muzyck sorry.. I didn't see that you already shared the link
It was probably minted in Korea, though. I know the Koreans won a contract to mint these around this time. Not sure when that contract began, but it was for the manufacture of these 1 Yuan coins.
