HC Deb 30 March 1911 vol 23 c1672W
Mr. FREWEN

asked the Secretary of State for Foreign Affairs, if he will state what is the rating of the silver yen to gold in Japan's artificial gold standard system, India's rupee reckoned at sixteen pence gold, representing, approximately, a ratio of gold to silver of one to twenty-two?

Sir E. GREY

According to the new gold standard adopted by Japan in 1897, one kilogramme of pure gold is coined into 1,333⅓ yen; that is to say, one gold yen contains.75 gramme of pure gold. The gold coins are minted 900–1000ths fine, and the weight of the 10 yen gold piece is, therefore, 8.3,333 grammes. The silver yen weighs 416 grains 900–1000th fine. Each silver yen, therefore, contains 374.4 grains, or 24.26 grammes of pure silver. The ratio between silver and gold is, therefore, as 32.34 to 1.
