Currency in the Border-Realms

The marrow of this post is lifted largely from a similar currency idea from this fine blog. 

First of all, some updates:

There'll be no news post this week, due to the isolated milieu of the players. Additionally, no session recap either, as not enough occurred to warrant a full recap. By next weekend both will have returned (the former provided the players also return to any form of established civilization).
Okay. Onto the meaty stuff.

In light of the ever-developing strata of this campaign, I've wanted to compile a post on various small details and occurrences that are common throughout the disk. This is that post. Throw all notions of effective and flowing format; this is more a compilation of random ephemera than it is a presentable, thematic presentation.
A lot of these things also warrant their own posts, which will no doubt occur at some point. That is to say, if considerable pressure is thrust upon me.

Currency and Money 

Throughout the border-realms and beyond, various local and backwater currencies (made of anything from silver and lead to hammered dreams and beaten souls), circulate in their respective spheres. However, only one denomination is trusted by merchants and sellswords across the world: the Electrum Grivna.

The grivna is hammered and minted in the Voivodeship of Czerogrod, cast of a distinct alloy primarily consisting of gold and silver. Although often pressed with localised iconography or script the grivna's size (comfortably fitting in the aperture of a touching thumb and forefinger) and value (ten grivna would buy a cow) are practically universal. The distinct electrum alloy, containing trace elements only known to Voivodeship mints, gives the coin a melodic character: struck against each other, they will produce a lasting and pleasant ring. It this easy trial of authenticity that has produced their infallibility as the merchant's standard (and excited the ear of many a hoard-hungry adventurer).

Other Currency: Perhaps the only other form of currency that could truly be considered global is the unassuming Padishah's Dinar. The ancient coin of the once-united Zukbar-Sihirbazik realm, this coin appears as a tarnished and unremarkable piece of silver (until further examination). It marked only with the image of an engorged and stinging sand-fly. These coins are only hammered and distributed by the Knives of the Padishah, an enigmatic guild of assassins practicing the ancient art of the Zukbari-Sihirbazik royal vizier-assassins. These coins are worth exactly one assassination attempt. That is to say, those who are not members of the guild and are found carrying them are marked for death by the Knives. Thus, they are distributed by the guild as a marker for assassins seeking their target, though how they know the possessor of each tiny coin is unknown. To pilfer one of these coins is to risk every day holding it, but to sneak it into another's saddle-bags or strongbox is to effectively mark them for death.
