Money

The primary medium of exchange (Money) for the purchase of goods and services from vendors within Middle-earth is coinage. There are three denominations of coin: Gold, Silver, and Copper.

• 1   (Gold) = 1,000   (Silver)
• 1   (Silver) = 100   (Copper)

As of Update 13, you can purchase (and redeem) "Bags of coin" from the Vault-keepers of Middle-earth. These can then be mailed, traded, or placed in your various shared storage vessels to allow the easy exchange of money between characters on your account.

•  Bag of Copper Coins - Worth: 100   at a Cost of 100  
•  Bag of Silver Coins - Worth: 1   at a Cost of 1  
•  Bag of Gold Coins - Worth: 10   at a Cost of 10
