Black

Large, black tantalum coins created and circulated by The Mint, whose original supply pre-dates the split.

The coins are a tantalum alloy that oxidises to a shiny black colour shortly after production. The oxide layer both gives the coins it’s characteristic appearance, and also (mostly) protects users from the mild toxicity of the tantalum metal. Despite the layer of protection, the black oxide has a strong metallic smell that stains the skin, and most people do not enjoy handling the coins.

The supply of black is limited, since new sources of tantalum are rare, and coins are slowly cannibalised to obtain tantalum for mixing. The current total number of coins is not known, but many are hoarded by wealthier citizens and old families. As a result, the value of black slowly increases, and is currently too high for it to be a functional currency for everyday needs in Longbridge. This shortcoming has given rise to the current system of promise notes.
