1588 Tensho Hishi Oban
To develop trade, Hideyoshi needs a gold coin. The very first, in the 16th year of Tensho corresponding to 1588 CE, is the oban defined by a weight of 10 ryo, of the variety Tensho hishi oban.
This coin is a 146 x 85 mm oval plaque weighing 165 grams. It is molded but not struck, and the weight is adjusted by plugs. It has ink inscriptions on both sides. On the obverse, the hallmarks feature the ornamental paulownia tree which is Hideyoshi's heraldic symbol, some inside a hishi lozenge and others inside a circle. The ink inscriptions include the identification of the date and of the Goto family of goldmiths, and the guaranteed weight of 10 ryo.

1870 Meiji 3 Pattern Yen
Know-how cannot be acquired overnight. At the start of Meiji 3, 1870 CE, Japan commissions the British to prepare prototypes. This operation covers eight denominations : 10, 5 and 2 1/2 yen in gold, yen in silver, and four subdivisions in white metal or copper.
The prototypes are sent to Japan and a British engineer arrives in Osaka. The dies are kept in London, which probably explains why the designs will be changed. All subdivisions of the yen are replaced by multiples of the sen, the decimal value 2 yen replaces the fractional 2 1/2 and the 20 yen is added. In June 1871, the government formalizes the creation of the yen. In the meantime, Japan had bought from a trading house the production line abandoned by the British in Hong Kong in 1868.
These British prototypes are very rare.
