 * The Yem-Shui Mk. IV cost 599,999,999,999.99 ISC.
 * The Baker payed for it with a LifeMufin, which was apparently far more valuable than the above price. ((SOURCE: EQ,P4-5))
 * Quadraxi: The currency of planet Earth before the Cataclysm.
 * Guitar Hero's bass cost "Eighteen and twenty-million quadraxi." He payed for it with the "Dragon's Tooth," which also outweighed the aforementioned price.((SOURCE: EQ,P4-19))

 * Porcelain Products cost 0.04.10 Schiff. They have yet to be purchased.
