Existing mysteriously in outer space, black holes were first predicted by Albert Einstein with his general theory of relativity. In 1916, Karl Schwarzschild then calculated the first modern solution of general relativity that would characterize a black hole.
In 1971, Cygnus X-1 became the first widely accepted black hole and, today, we remain fascinated by these enigmatic astral giants. That fascination includes the supermassive black hole, Sagittarius A, thought to be at the centre of our galaxy!
Now, 100 years after Schwarzchild’s general relativity solution, this new coin, exclusively designed and commissioned by Melbourne Mint Coins, depicts a supermassive black hole in bright, bright colour. Struck in relief, the swirling light and debris spiral down into the coin, culminating with the jet-black circle in the centre of the black hole.
Limited to a maximum mintage of 999 pieces, each Supermassive Black Hole coin comprises 1oz of 99.9% pure silver and measures 38.74mm in diameter. Finished with the ever-popular antiquing process, each of the debris flecks, conversely, have been highly polished to provide a subtle, yet beautiful, extra nuance.
