An Ill-Gotten Token
Xariah's spintria sell for hundreds or thousands of gold; but they ultimately belong to whoever's in possession of them, and they're always redeemed with no questions asked.
Sometimes they might be stolen, and a lowly thief finds and enjoys an unexpected surprise in the coin pouch he lifted off the wealthy-looking mark in the marketplace. Sometimes a wealthy gambler might overestimate his chances at the game table and put one up into the pot as a bet, only to see it disappear into another's hands as fate turns. And rarely, very rarely, one just gets misplaced or forgotten; finding its way into a street gutter or along a roadside where some curious scavenger investigates the metallic glint of reflected sunlight.
Whatever the circumstance: he who has the token, gets the girl.
