Made of aluminum (a wartime strategic material that I wouldn't expect to be expended in coin production), 22mm in diameter. Ten sen equals a tenth of a yen. Mintage was astoundingly large, almost 945 million. Colligo ergo sum Report this Post to the Staff

The same name appears on the Gold yen from the 1870s. After the war, the name changed to "Nippon koku" (Japanese State). The year is indeed 1942 (17th year of the Showa Emperor). Quote: Made of aluminum (a wartime strategic material that I wouldn't expect to be expended in coin production) In WWII, aluminium was a less critical war metal than copper; 10 sen coins prior to 1940 were made of aluminium-bronze (a mostly copper alloy). Still, as even aluminium became scarce in Japan towards the end of the war, the size of the 10-sen coin was reduced. They considered, but ultimately rejected, making 10 cent coins out of baked clay. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff

Well, as you can tell, I just don't know very much about Japanese coinage. When I showed this example today to someone who reads Kanji, she immediately translated it as "Big Japan" and that's how it's also interpreted on this website: http://en.numista.com/numisdoc/japan-51.html so I took that to be correct (notice as well that this website is singularly unhelpful on why or when coins were so marked). In any event, I can see how "Great Japan" while perhaps less literal almost certainly captures more correctly the sense of what was intended to be conveyed. At least I dated it accurately.

nalaberong Pillar of the Community Canada 2805 Posts	Posted 02/23/2015 10:25 pm Nice, nice. Here's some of my Japanese small change. 5 sen, 1943 5 sen, 1946. I think these are from after the Japanese surrender - hence the large Western numerals and change away from "Dai Nippon". Not a wartime issue, but I really like the design: 10 sen, 1929 10 sen, 1943. Look familiar? 10 sen, 1946. Also from immediately after the surrender. For a provisional coin that was probably designed very quickly, the design is quite nice. Report this Post to the Staff
