Six Finger Guild
The first coins were minted, by elves, as tokens of friendship. These early coins were large, heavy, and ornately carved on one side. They were often made of bone, shell, ornamental stone, precious metals, or gemstones. (Most humans would probably identify these coins as amulets.)
Humans were soon trading and forging them, making regulation necessary. Coins are generally struck at official government mints, but sometimes Master Jewelers will be awarded a contract/license to make coins for a fixed period. The penalty for making coins without permission of the authorities is death.
Coins are generally made from precious metals, and nearly always decorated on both sides. Some coins have scalloped edges to help identify trimmed coins. Common coastal gold Guilder has an approximate weight of one-eightieth of a pound. (80 Coins to a pound.)
The coastal coin is the accepted standard and most cities produce coins to the same specifications. Dwarven coins are sought after for their strength and purity. Conversely, the island coins are difficult to pass on the mainland due to the chronic problems of clipping and debasing.
Most transactions involving a large number of coins (over a hundred) are conducted by weight. The merchant will use a balance scale with a known set of measured weights.
