Comment
Made by the Shimazu clan at Ishonohama, the political center for Satsuma and the Ryūkyū (Okinawa). The coins were intended for trade with the Ryūkyū but were apparently used very little.It's said their production was meant as a smokescreen for the production of illegal Tempo 100 mon coins.
Sample coin is a DHJ#6.28
Interesting fact
The Ryūkyūtsūhō coin was the first coinage introduced by the Kingdom of Ryukyu (now part of Japan) in 1862, and it was made of copper. It weighed 22 grams and had a standard circulation of 100 Mon. This coin was an important step towards modernizing the Ryukyuan economy and was used widely in the kingdom until its abolition in 1879.
