12th Century monetary units

Despite having only one type of coin (see 12th Century Coins), names existed for different monetary units in multiples of these coins. The larger units may only have been used at money changers, when converting coin to foreign coin, not in general use.

• A 'denier' was one silver penny
• A 'sou' was 12 deniers
• A 'marc' was eight ounces of pennies
• A 'livre' was twelve ounces of pennies
