[QUOTE="hontonai, post: 1492861, member: 4703"]The center coin is correctly oriented, the others should be rotated 180 degrees. I specialize in coins from 1867-1945, but the hole in the coin on the left appears to be larger than the holes in the other two. Both types are from the TenpoTsuho period (1835-70) marking the end of the Tokugawa Shogunate and the beginning of the Meiji Restoration According to Munro's [I]Coins of Japan[/I], published in 1904, the coin was still circulating, with a value of 8/10 of 1 sen. Munro also reports that the star impression on the edges of your coins indicates that they were issued late in the series' life. Although the nominal metallic content was 78% copper, 12% lead and 10% tin, they are known to exist in brass, bronze of various compositions, and even iron. Munro said there were about 20 varieties and the current Japanese Numismatic Dealers Association catalog shows 24, all varying in virtually imperceptible forms. Krause shows only two versions, with the different size holes, and a comment that there are multiple varieties of the small hole type.[/QUOTE]
