The coin ages with its capital

The centre of a coin never changes. Around it the renderer reads one number from the contract: lifetime yield over backing, in basis points. Claiming yield does not lower it; selling the coin does not reset it. It only goes up, and the ring follows it through 14 levels: one orbit each for the first four, then the orbits fill in, then sparks between them, then the orbits take the accent colour.
