Artificial Intelligence looks to a future that is both fascinating and unforeseeable. The coin’s reverse features the outline of a head that symbolises our ignorance about the future functioning of humanoid ‘super intelligence’. The fact is that we do not know what will happen when artificial intelligence has worked out how to improve itself and no longer relies on us. Will it imprison us or will it set us free? Only time will tell, but in the meantime the thought-provoking 2019 addition to our bestselling Silver Niobium series uses its electric-blue niobium core and silver outer ring to beautifully visualise our uncertainty.

The footprint of humanity on the Earth is unfortunately a massive one. So big that experts now agree that humanity’s impact on the planet is so profound that it is time to declare a new geologic epoch – the Anthropocene. Examples of this impact are the radioactive elements dispersed across the planet by nuclear testing, plastic pollution and the soot produced by fossil-fuel power stations. These and other adverse effects are illustrated in exquisite detail on Anthropocene, the 2018 edition of our ever-popular Silver Niobium coins.
