1863 Ryukyu Tsuho 当百 – Large Cash Coin of the Ryukyu Kingdom
⸻
🌏 Historical Context
In the mid-19th century, the island kingdom of Ryukyu Kingdom stood at the crossroads of East Asian trade.
For centuries, Ryukyu maintained tribute relations with China while simultaneously being controlled by the powerful Japanese Satsuma Domain.
To support commerce within the islands and regional trade networks, a distinctive currency was introduced in 1863 — the 琉球通宝 (Ryukyu Tsuho).
These coins were minted under the authority of the Satsuma Domain but circulated primarily in the Ryukyu Islands.

⚖️ A High-Value “100 Cash” Coin
The example shown here bears the inscription 当百, meaning “value of one hundred cash.”
Unlike typical small round coins used throughout East Asia, the Ryukyu Tsuho was produced in a large oval form, making it immediately recognizable.
Your specimen:
• Diameter: 49.1 mm
• Thickness: 2.6 mm
• Weight: 21.2 g
Its imposing size reflects its role as a high denomination coin used in large transactions.

⚒️ Design and Calligraphy
The obverse features the bold vertical inscription:
琉球通宝
meaning “Circulating Treasure of Ryukyu.”
The reverse bears the denomination:
当百
indicating a value equivalent to 100 standard cash coins.
This combination of Chinese-style characters, Japanese authority, and Ryukyuan circulation makes the coin a fascinating hybrid of East Asian monetary history.

📜 A Coin from the End of the Samurai Era
The Ryukyu Tsuho was issued during the final years of Japan’s Edo Period.
Just a few years later:
• The Meiji Restoration (1868) would transform Japan
• The samurai system would be abolished
• The Ryukyu Kingdom would eventually be annexed and become modern Okinawa
Coins like this therefore represent the last decades of the traditional East Asian tribute and feudal economic system.

💎 Why Collectors Treasure It
Collectors highly value Ryukyu Tsuho 当百 coins because they represent:
• The historic Ryukyu Kingdom trade network
• Japanese feudal domain coinage
• A rare large denomination cast coin
• Unique oval coin design
• A fascinating blend of Chinese, Japanese, and Okinawan history
Large examples with strong details and professional certification are particularly desirable.
