* The Tiberian Empire is the larger economy, but it has struggled in recent centuries to prevent the debasement of its currency. The coins of Khartras for at least one hundred years have been the most reliable stores of value, and King Martin’s mints and regulators work hard to maintain the integrity of the coinage.
** Some kings tried a large silver mark, a coin valued at 4 shenars. Merchants generally dislike the coined mark because it was underweight and caused confusion with their unit of account (13s4p), but some kings’ treasurers liked its fractional utility and its effect of increasing the number of coins in circulation.
*** The guinea was not a coin. It was a value of account used by gentlemen to display their generosity and unconcern for money. One might pay a guinea for a crown’s worth of merchandise.
