The Merchant Coins may add 2k2 to any roll regarding business, commerce, trading or other negotiations involving profit. The coins only work during the hour of the day to which their symbols correspond. I.e. the coin with the symbol of the Boar will only work during the hour of the boar. Outside of the hour on the coin they merely add an additional rolled dice. The additional dice from the coins (the 2k2 or the extra rolled ones) may be ignored to gain a re-roll instead.
