Eastrun Coins

Eastruners use a thin square iron coin in three denominations: wonjen, tinjen, and henjen. Each coin is stamped with the name of the minting house on one side and the character for the amount in the other. Because each house may produce its own currency, the coins represent a promissory note against that house's treasury. Coins are often kept on specially designed cords which are threaded through the coins.

There are about 100 iron coins to the pound.
