System currency
Produced mostly by local merchant guilds, a planetary governor or noble houses.
Usable only within the systems controlled by a prominent instance issuing the local currency. They rarely contain precious metal enough to be considered other than symbolic value backed up by the wealth of an instance distributing them.
“Imperials” are generally worth of 10 standard imperial ratios.
“Eagles” are generally worth of 100 standard imperial ratios.
Ingots of valuable metals and minerals
Those have a good trade value as there is constant need for certain materials desired by the forge worlds of the Imperium. Using radioactive materials as a hard currency is frowned upon by arbitrators, inquisition and Adeptus Mechanicus. Official reason is the mutating effect of those materials but there is a genuine fear of uncontrolled trade of nuclear materials that can be used for dirty bombs by recidivists and heretics within the Imperium.
Gemstones/crystals/diamonds
Easy to carry and conceal and their worth can be equal up to an Imperial planet or a star fleet. Some are xenos origin and may pose additional moral threats. Galactic production of precious stones in the Imperium is largely consumed by shrine worlds of the ecclesiarchy and lance weaponry produced by forge worlds.
Throne Gelt Dark Heresy corebook page 124, edited for Ultima Tectum campaign.
An universal and a rare hard currency across the Imperium. The worth of an any local currency is compared to the worth of the Throne Gelt. The coin itself is produced at Terra and distributed to Imperial authorities. It is iron coin that contains a speck of dust from the soil of Terra and it’s worth is symbolic. It is too rare to function as a method of payment, but acts as method of standardization within Imperial commerce. Worth of one Gelt is standardized to 1000 standard imperial ratio coupons. Imperial aristocracy calls it “An Imperial penny”.
Imperial Bond Dan Abnett: Xenos, edited for Ultima Tectum campaign
Commonly used by different Imperial Ordos. It usually is a parchment provided by person of Imperial authority and can be claimed at any Imperial world. Ultimately it is paid from budget of a systems Imperial Governor and is deducted from Imperial Tithes paid to particular Ordo at a system. Many Imperial bonds are not claimed but used as a currency between Imperial citizens and instances. It is possible that along Imperial history more unclaimed Imperial bonds have been warranted than the economy of Imperium is able to refund.
